P&E’s product line of Cyclone stand-alone
programmers
provides a fast, robust, and automated solution for production-scale
programming of microprocessors. However, production facilities may
desire an
even higher level of automation than the single-button touch capability
that is
offered by the Cyclone. P&E offers several means of automating
control, including a command-line executable, UDP/Serial
communications, or the .DLL included in P&E's new Cyclone Automated
Control Software Package. In this article, we discuss automated control
using the automated control package and the unprecedented level of
power and flexibility that
it offers.
Click through to learn more about the Cyclone Automated Control Package.

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. In this post we discuss why these reset scripts are necessary and also analyze the contents of these scripts in detail. Click through for more.

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. Click through to view the example and follow along.

Did you know you can safeguard data while erasing your flash module
during Flash/EEPROM programming? P&E has added a “preserve range” function
that can be used in a programming algorithm to preserve memory
ranges. The function looks at the range to be preserved, saves it, and
restores it after the flash has been erased. Click through to see how to take advantage of this new feature.

P&E has added a new Chip Select Diagnostic mode to its interactive
flash programmers to allow the user to diagnose memory map configuration
problems.
P&E’s flash programmers support an extensive array of
external flash devices connected to the processor. P&E’s algorithms are designed to work by default when
the flash device is connected to the boot chip select and no modification is
needed to the reset configuration of the output enable and write enable lines. However, there are numerous ways in which the flash can be
connected that may require changes to the default reset configuration
of the processor’s chip select, write enable, and output enable operation.
When another configuration is used, the algorithm may
require some modification to work. Click through to see an example of a typical modification to a P&E algorithm, as well as how to run the new Chip Select Diagnostic tool.
