PEmicro supports external flash connected to an MCU via the SPI and Address/Data bus interfaces. When performing this type of programming, the algorithm needs to be set up specifically for our programmers to be able to communicate with the flash via the MCU. What must be configured depends on which external bus interface has been chosen for the connection. When using the Address/Data bus, the user will need to configure the external address, data, and bus control pins of the MCU. In the case of the SPI bus, the user will need to configure GPIO pins connected to the external SPI device properly. The modifications are made in the header of the algorithm file. PEmicro's PROGACMP software, as of version 8.84, has an SPI Diagnostic mode that provides the user with a new method to easily test the GPIO configuration in order to help troubleshoot programming issues.

PEmicro has added production programming support for the Renesas RA family Device Lifecycle Management (DLM) and TrustZone boundary settings to the Cyclone FX programmer. Device Lifecycle Management and TrustZone boundary settings are used to secure access to the on-chip Flash and Ram both from external debug/bootloader access as well as untrusted code running internal to the device on devices with DLM Technology and TrustZone support (such as Cortex-M33 devices). Configuration and programming of these settings is made simple with PEmicro's stand alone programmers.

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.

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.

PEmicro has improved user reset capabilities after a flash programming sequence. With the updated implementation of the ‘GO’ command (available with most ARM Cortex processors) in both PEmicro's Cyclone and PROGACMP software-based programming solutions, the user is able to specify the use of a software or hardware reset to reset the MCU.

PEmicro's Multilink Universal (part# USB-ML-UNIVERSAL) recently changed from Rev D. to Rev. E. As part of this update, Multilink Universal Rev. E or later will require an adapter when communicating with NXP's RS08 devices.

The RS08 connection otherwise remains the same, and uses the same 6-pin pinout described in the Multilink Universal technical summary.

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.

PEmicro's Cyclone programmers and Multilink debug probes now support Nordic Semiconductors' nRF53 devices. These are low-energy, short-range devices capable of both perfomance and efficiency.

The nRF5340 SoC, for example, is the world’s first wireless SoC with two Arm® Cortex®-M33 processors. It's an excellent choice for LE Audio, professional lighting, advanced wearables, and other complex IoT applications, due to those two flexible processors, its advanced feature set, and an operating temp up to 105 °C.

It also includes Bluetooth 5.3 SoC which supports Bluetooth LE, Bluetooth mesh, NFC, Thread and Zigbee.

PEmicro has added "Cyclone Programming Control Port" functionality to the 10-pin expansion I/O interface on the Cyclone allowing external signal control of programming operations. The Cyclone Programming Control Port may be used to launch programming as well as read the IDLE/BUSY state of the cyclone and the SUCCESS/ERROR result of the last programming operation. The port I/O operates from 1.6v-5.5v. These signals can be interfaced to by ATE (Automated Test Equipment), external buttons / LEDs, microcontrollers, etc.

As part of the production programming process, Cyclone programmers have the ability to program and run a series of custom test applications in the target processor before final programming is allowed to occur. These custom test applications are written by the end user and include any functionality desired including test and calibration of the target system. The custom test applications indicate to the Cyclone through the debug interface whether they were successful or not and also optionally return generated data to the Cyclone for use later in the programming process. If all of the custom test applications pass, the final application is programmed into the target.
