Guide for Users Transitioning From Legacy Hardware

As technology evolves over time, PEmicro occasionally retires hardware and software products and classifies them as Legacy items, which are no longer sold or actively supported. When this happens there will almost always be a newer product available as a replacement part, accompanied by a substantial grace period that gives customers time to plan and adapt as necessary. PEmicro tries to make the transition to newer products as painless as possible, so our new products are often drop-in replacements with few additional updates required.

Securing Renesas RA/Synergy Devices via ID Code Protection

Update: as of Feb 20th, 2024: the process for programming OSIS region on Renesas RA processors is greatly simplified and no longer relies on user functions. ID Code Authentication is now also handled directly in the PEmicro software instead of an external Python script

It is crucial to be able to prevent access by third parties to on-chip flash memory. Renesas RA and Synergy devices offer several means of security, one of which is called ID Code protection. After the MCU starts up in boot mode, ID authentication is performed when a host such as a PC is connected, in order to prevent unauthorized access. PEmicro's tools now allow users to take advantage of ID Code protection within the OCD/Serial Programmer ID Setting Register (OSIS) of supported Renesas ARM processors.

Cyclone Programming Overview for STMicroelectronics Devices

The process of setting up Cyclone programmers to perform production programming at a local or remote facility is simple and straightforward. PEmicro's Cyclones support programming of STMicroelectronics' popular STM32 and Bluetooth Low-Energy (BlueNRG) devices, as well as the SPC5 automotive and STM8 8-bit families.

In addition, Cyclone programmers leverage PEmicro's ProCryption Security to use industry-standard RSA/AES cryptography to safeguard programming images containing valuable IP. The IP owner also gains added control over factors like when and how many devices can be programmed, and how many errors are allowed.

This article will provide an overview of Cyclone programming - what the various components are and how they interact - and then explore the security aspect of the production programming process, in order to show that IP security does not need to be unduly complicated or expensive to be effective.

Errata for USB Multilink Universal Rev. E

The following is an errata sheet which concerns a potential issue with some versions of USB Multilink Universal Rev. E, including how to determine if the user has the affected product, the specifics of the issue at hand, and what the current solutions are. 

Summary: Reset signal (pin 4) on Port C does not toggle. This can potentially cause debug entry problems for the following NXP processor families: HCS08, HC(S)12(X), S12Z, ColdFire+ V1, and ColdFire V1. However, many of these processors do not require the reset signal for debugging and will not be affected by this errata. The HC(S)12(X) and S12Z processors are expected to be the most impacted.

Affected products: This errata affects part number USB-ML-UNIVERSAL Rev E with date code 1121.

Overview: OS-Aware Debug Support for Azure RTOS ThreadX in GDB Server, MCUXpresso, etc.

Version 5.1.4 of PEmicro's GDB Server for ARM devices, is required to support for Azure RTOS ThreadX. The user does not have to do anything to set it up; the GDB server will automatically detect the presence, type, and configuration of an OS by the querying the application's symbol table for identifying characteristics. Using these discovered symbols, the debugger can traverse the kernel's internal data structures to enumerate the available threads and their corresponding execution context. This information is then used to dynamically populate the Eclipse views as the user navigates between the threads.

Verifying a programmed device via Checksum

The most common mechanism for verifying a programmed device is via the Verify Module command which verifies programmed memory against object files on a byte-by-byte basis. PEmicro also has several verification mechanisms which use Checksums/CRCs.

The Verify Checksum (VC) command automatically calculates checksum values for all flash memory ranges in a user's object files. The programmer then runs an algorithm to calculate checksums for these device regions and compares it to the ones calculated from the object file. The advantage of this method is that it is faster than byte by byte verification when the debug connection is slow.

The Verify Module CRC to Value (VV) command calculates a checksum for the entire device and compares it to a value provided by the user. This is often used as an addition step after byte by byte verification to check the state of the entire flash (even unprogrammed regions).

Programming Paged Flash for HC(S)12(X) Microcontrollers

The HC(S)12(X) microcontroller family uses a paged flash architecture to expand its addressable memory beyond the standard 64KB (or $0000 to $FFFF). Microcontrollers with this feature treat a 16KB block of memory from $8000 to $BFFF as a memory window.  This window allows multiple 16KB blocks to be switched into and out of program memory.  An 8-bit program page register (PPAGE) tells the microcontroller which block to read.
