PEmicro’s GDB server can be installed directly into an Eclipse based IDE from an update site on PEmicro’s website. This adds the ability to debug via PEmicro’s Multilink, Cyclone, and OpenSDA hardware interfaces via the standard GDB debugger. Features include flash programming, breakpoints, watchpoints, trim, memory preservation, real-time variables, semi-hosting, and more. PEmicro periodically updates the plugins on its website with new device support, new features, and bug fixes.
Different targets require a different power schemes that depend on the design of the target board, target voltages, and even the device architecture. PEmicro has designed their CYCLONE and CYCLONE FX to optionally power a target before, during, and after programming. Power can be sourced at many voltage levels from the Cyclone itself or sourced by an external power supply and switched by the Cyclone.
The CYCLONE and CYCLONE FX programmers from PEmicro have large 4.3” touchscreens which allow the user to see the Cyclone’s current status, select programming images, configure settings, and more. However, sometimes the Cyclone may be either at a remote location or physically inaccessible. For example, Cyclone programmers are often mounted within enclosed test fixtures and sometimes even have the screens physically removed to save space. In any of these cases, the touchscreen can also be accessed remotely, via Ethernet and USB.

P&E engineer Edison Tam demonstrates how to program
Freescale's QE128 with P&E's Cyclone PRO stand-alone automated
programmer, and gives an overview of the development and production
capabilities of the Cyclone PRO. To learn more, please visit the Cyclone PRO product page:
Did you know that P&E offers full chip simulation for all 8-bit Freescale devices? This powerful tool allows you to jump start device evaluation and firmware development because you can start writing code without having access to the actual device. All aspects of 8-bit devices from the CPU to the external I/O can be analyzed in a full-chip simulator.
Because of the importance that external I/O plays in development of any embedded system, P&E's full chip simulator gives the user access to all onboard modules via a combination of input/output GUIs and commands. The user can simulate sending and receiving data to and from modules such as SCI, SPI, IIC, ADC and PGA. At the same time the user can also simulate analog inputs on bi-directional I/O ports, which can be used to trigger keyboard interrupt events if the KBI module is properly configured. Availability of the modules mentioned above depends the actual device.
Currently, all P&E full chip simulators are available through fully licensed and evaluation versions of Freescale Codewarrior IDE. However, P&E plans to release a stand-alone product which will include simulation for 8-bit Freescale devices.
Below is a code snippet that can be used to perform an SCI transmission. Once the transmission takes place, it can be observed in the SCI output buffer window:
P&E's ICD In-circuit Debugger and PROG Flash Programmer software, included with the Starter Editions, natively supports several object file formats, including s-record and ELF. Soon, P&E software will natively support Intel Hexadecimal files.
After installing one of the Starter Editions, run OBJCOPY from the Windows command-line. The program is located in the gnuin subdirectory within the installation directory. View the help screen for OBJCOPY from the command-line by typing "powerpc-eabispe-objcopy" or "m68k-elf-objcopy". You will see a list of all program options. To determine which formats are available with OBJCOPY, take note of the final lines of the help screen. You will use these format names, BFD names, when running OBJCOPY.
To convert a file, use the "-O" option followed by the name of the desired output format. The input format may be specified with the "-I" option, though this is often unnecessary. For example, to convert the object data in a COFF file "file1.coff" to an s-record file "file1.srec":
If you are looking for greater control of file conversion, look at the options on the OBJCOPY help screen. For example, with powerpc-eabispe-objcopy you may specify s-record length, force S3 records, and manipulate the linker sections in object files.
Did you ever wonder how to power cycle your device to force it into
Background Debug Mode? Are you trying to eliminate an external
power supply from your manufacturing setup? You can accomplish either task by using
a Cyclone PRO. Using the Cyclone PRO's internal power generation mechanism, you can control power for any HC08/HCS08/RS08/HC(S)12 device.
In fact, controlling the power through a Cyclone PRO is crucial for
HCS08/RS08 device applications which may not have a dedicated RESET
pin. This is because power cycling the device is necessary in order to fully automate the
FLASH programming procedure.
To configure a Cyclone PRO to provide power to pin 6 of the BDM
header, set power jumpers 2, 3 and 4 on the side of the Cyclone unit. To
provide power to pin 15 of the 16-pin MON08 header,
set power jumpers 1, 2 and 3. Once the power jumpers are set,
select "Provide Power to Target" from the Connection Assistant and/or
Cyclone Image Creation Utility and the Cyclone PRO will take care of
the rest. You can choose between 5V, 3V and 2V levels.
Cyclone PRO is also able to toggle power for most high-power/high-voltage devices. The internal electromechanical relays can handle power supplies with a maximum switched current of 1A and a maximum switched
voltage of up to 30VDC. In order to automate power cycling with an
external power supply, insert it into the Cyclone's "Target Power In" jack. Use the power cord that's included in the Cyclone PRO kit to
connect the output of the Cyclone's "Target Power Out" jack to the power input of your
board. Then be sure to set power jumper 5 on the side of the Cyclone unit, leaving jumpers 1, 2, 3 and 4
ICDPPCNEXUS, P&E’s in-circuit debugger for the MPC55xx/MPC56xx processors, uses reset scripts to properly initialize the device when it comes out of reset. When these devices power on normally, the Boot Assist Module (BAM) automatically performs a default startup initialization.
However, if the processor is forced into debug mode, the BAM does not execute. Because of this, many of the processor’s resources, such as internal FLASH and internal SRAM, are not available until a proper reset initialization is manually executed. The ICDPPCNEXUS debugger uses reset script files to specify the exact initialization that should be performed immediately after the processor is reset and debug mode is entered.
ICDPPCNEXUS includes a set of these reset script files which initialize the processors with a standard configuration. These files have a .mac extension and can be viewed/edited with a standard ASCII editor such as Windows Notepad. Let’s take a look at some of these script files in more detail:
These commands set up an entry in the MMU to map the internal SRAM to begin at address 0x4000_0000. This is accomplished by writing to the MMU Assist Registers (MAS0 – MAS3) and then executing the “tlbwe” instruction. This type of setup is typically repeated for internal FLASH and peripheral modules.
Fatal errors can occur if an interrupt is triggered and the interrupt vector address points to an invalid memory region. The above commands configure vector addresses to point to the beginning of SRAM, which is a valid address.
This command initializes SRAM from 0x4000_0000 to 0x4000_FFFF by writing random data to this entire memory region.
The last example above is device specific. The SWT watchdog is disabled by writing a 0xFF00_000A to address 0xFFF3_8000. The core watchdog is also disabled by writing a 0 to SPR 340.
In a previous post, we showed how to use PKGPPCNEXUS and PKGCFZ_PRO to display the contents of an ELF/DWARF file using Readelf. In this post, we look at the Readelf output and explain its description of your object code.
We will use this example Readelf output to illustrate the kinds of information that Readelf provides.
The first item of interest is labeled "Entry point address". This is the address of the first instruction executed after reset. Your compiler or linker determines this value. The P&E debugger optionally uses the entry point address to execute your target application.
The "Section Headers" portion lists all of your linker sections that made it to your ELF/DWARF file. The ".debug_info" section is where ICD looks for the debugging information entries. Note that not all of these sections contribute to the application memory map.
The portions titled "Program Headers" and "Section to Segment mapping" describe the application memory map. ICD and PROG use the program headers to determine where to place object code on your target. Check that a linker section is included in the final memory map by examining the section to segment mapping. Note that the first entry in the program headers corresponds to the first entry in the section to segment mapping.
From the program headers, you can gather the following information about the memory map: Type - Only LOAD types contribute to the final memory image VirtAddr - load time location of code MemSiz - number of bytes that the code segment occupies in the final memory image
P&E's PROG and ICD software support an uncommon feature of the GNU compiler. GCC uses both the program header VirtAddr and PhysAddr fields, the former for run time address and the latter for load time address. For more information on this useful feature, please refer to this document.
Certain test procedures and production environments
require the use of a cable longer than the typical 9-inch flat ribbon cable
typically included with P&E hardware interfaces. Extending the cable length
requires special considerations for signal integrity, crosstalk, and
electromagnetic interference. Simply using a longer cable without understanding
these topics will usually produce a setup that does not work reliably, if at
all. Extending the ribbon cable should be the option only if you determine that you cannot make longer the length of the USB, Ethernet, or Serial cable that connects the P&E hardware interface to your PC. The cables for the communication ports already have some shielding.
is necessary to use a longer ribbon cable, P&E recommends using a shielded jacketed cable . This cable configuration is excellent at
reducing crosstalk as well as minimizing electromagnetic interference from
other devices. Further improvement can be obtained if the wires are also arranged
in twisted pairs.
Shielded USB cables are inexpensive and easy to rework. The
four wires provided can be used to create a cable for the standard 6-pin BDM
header used by many Freescale microprocessors (such as the HCS08, RS08, CFV1, and HCS12). But this option won't work for other devices that require more debug pins.
In general, these guidelines should be followed for all cables between the target microprocessor and the P&E hardware interface:

dependent on the processor's bus
frequency. Reducing the bus frequency (ie. disabling the PLL) should
The debug signals for some ColdFire devices such as the MCF5272 and MCF5206 have to be synchronized before reaching the microprocessor. This additional requirement must be kept in mind.
For time-sensitive HCS08/RS08 applications the developer often needs to trim the internal reference clock in order to generate a desired bus frequency. P&E's HCS08 and RS08 Flash Programmers provide a command called “Program Trim” that allows developers to program a pre-calculated value to the non-volatile flash locations that are reserved for storing ICSTRM and ICSSC registers. These can then be loaded at run-time.
Here’s a demonstration of how the “Program Trim” command can be used to generate a bus frequency of 8 MHz on a 9S08QE128 microcontroller. For the 9S08QE128, the “Program Trim” command will generate a value that will trim the Internal Reference Clock to 31.25 KHz with an accuracy of up to +/- 0.2%. The command will then program the generated value to 0xFFAE and 0xFFAF. We will be working with an assembly file that configures the Internal Clock Source module and toggle Port A every 20 CPU cycles.

After saving the above source file section as "9S08QE128_Example.asm" and assembling it, we can use PROGHCS08 to program the generated 9S08QE128_Example.s19 file into flash. The programming sequence outlined below will program our generated .S19 and the pre-calculated trim value.
CM ; Choose module 9S08QE128.S8P SS ; Specify our object file 9S08QE128_Example.S19 EM ; Erase module BM ; Blank check module PM ; Program module VM ; Verify module PT ; Program Trim Value
On a power-on reset, our 9S08QE128 target will disable the watchdog, load trim values from flash and store them into their corresponding ICS registers, set the bus frequency divider to 1, and toggle PTA pins every 20 cycles. With a bus frequency of 8MHz, if we were to put a scope on any of the PTA pins, we would expect to observe a signal with a 400 KHz frequency +/-0.2% accuracy.
If you use the ELF/DWARF file format with P&E's Programming or Debugging software, download one of our free C development kits to view the information within the ELF/DWARF file. Use Readelf to examine your application memory map, check your linker script, determine application size, view detailed debugging information, and more.
We include the GNU Readelf utility with our C development kits, PKGPPCNEXUS for PowerPC 55xx and PKGCFZ_PRO for ColdFire. These packages give you a complete set of development tools including the P&E ICD debugger, PROG Flash programming software, register viewing software, WinIDE editor, target specific project templates, and a GNU compiler toolchain.
You can control Readelf and the entire compiler toolchain from WinIDE. During compilation, you can automatically process the compiler output file with Readelf and dump the information to a text file. Also, take advantage of Readelf with any target architecture - if you're not targeting ColdFire or PowerPC 55xx, you can install one of our free C development kits and use WinIDE as a stand-alone ELF/DWARF viewer.
Did you know that P&E provides simulation for nearly the whole array of Freescale 8-bit microcontrollers (RS08/HCS08/HC08)? Simulation is inexpensive and fast, and allows for a highly detailed look at the functionality of the simulated device. P&E Simulations include trace capabilities and are cycle-accurate (cycle accuracy allows for a low level, cycle-by-cycle analysis of the timing and general functionality of your code). Furthermore, simulation allows the seamless loading of code to the
entire memory array of the processor, without the cumbersome flash
burning that accompanies hardware development -- and byte by byte modification of the memory is allowed at any time.
In addition to initial development, simulation can serve as a highly effective means of product evaluation. Evaluation of various devices via simulators can be relatively painless and inexpensive when compared to evaluating those same devices using actual hardware. In addition, our simulations are often published before the silicon is widely available, so simulation is also an excellent tool to help you stay on the cutting edge.
Currently, P&E Simulations are available within the Codewarrior toolsuite. However, P&E will soon be releasing the Simulation Toolkit, which will include all simulations in one convenient package. Stay tuned to the P&E Newsflash for more updates on the release of this product.
P&E offers a set of In-Circuit Debuggers that are packed with powerful scripting features. Whether you are stepping through a couple of lines of assembly code or debugging a C-level source, P&E's toolset can help you get the job done. P&E's In-Circuit Debuggers are designed with repeatable test and debugging procedures in mind. Therefore, the user can completely automate software tests by creating a macro script and saving the outcome in a log file. As a result, the user can avoid hours of repeatedly setting up software and firmware tests.
Here's a small demonstration of how the built in macro commands can be used to create and perform a repeatable firmware test on a 9S08AW60 processor. We'll be working with a simple assembly loop that's designed to toggle Port A every 20 CPU cycles. Please note that while the example below will be based on ICDHCS08 debugger, the same set of macro commands is present in all P&E debuggers. For a complete set of built-in macro features, please refer to the ICD COMMANDS section in the corresponding ICDxx.hlp file.
The macro outlined below will load our loop_example.s19 and .map files. At the same time it will set the program counter, set the breakpoints, and initialize variables. As the code executes, it will also capture the contents of the desired registers as well as the contents of all on-screen windows. All information will in turn be stored in a log file for later comparison and analysis:
; creates log file
; load an .s19 with a map file
; set program counter to point to the beginning of the
; add a variable to a variable window
; add a variable to a variable window
; run through initialization part of the code to the loop
; dump the contents of registers $00 to $01 into the log
; set a breakpoint at the beginning of the loop
; run the code until it hits a breakpoint
; captures the current data in all open windows and stores
; them in a log file.
; close log file
To execute the above macro, enter “macro” in the command line (located on the bottom of the ICD status window). Browse to the location where your macro is saved and open the file. Please note that any built-in commands can also be executed individually. This gives the user the opportunity to perform a step-by-step test of the macro prior to starting the automated debugging procedure.
P&E has updated its ColdFire software products so that they no longer require use of the processor status (PST) pins on the debug connector. These pins are traditionally used to determine if the part is running in user mode or halted in debug mode. The default is still to use the PST pins for status, but this can be optionally disabled in the connection assistant. When disabled, the software will use the BDM communications pins to determine the processor status. This results in a slight slowdown in communication and download rates, but the advantage is that the target board no longer has to wire the PST signals to the debug connectors. This also alleviates some problems in the case where the customer application needs to make use of the alternate functions of the processor status pins instead of using them for debug.
