Debug tool migrates to MIPS32, Cortex-A8

Feb 24, 2009 — by Eric Brown — from the LinuxDevices Archive — views

Ronetix continues to add to its library of firmware for its Linux-friendly JTAG/BDM emulator and flash programmer. The PEEDI JTAG/BDM Emulator and Flash Programmer now supports MIPS32 processors, and in recent months Ronetix also added support for processors based on ARM Cortex-A8 and… Cortex-M3 cores.

Existing firmware for the PEEDI (“powerful embedded Ethernet debugging interface”) includes packages supporting ARM7, ARM9, ARM11, XScale, ADI Blackfin, Freescale Nexus-enabled PowerPC and ColdFire processors, and most recently, Freescale's PowerPC-based PowerQUICC II Pro processors.

The PEEDI firmware supports both debugging and flash programming on MIPS32 and ARM Cortex-based processors, says Austria-based Ronetix. The company lists Microchip's PIC32 microcontroller and the Infineon ADM45120 processor under its supported MIPS32 targets.

Since the PowerQUICC announcement in December, the company has also apparently added support for the ARM Cortex cores. The company lists only one specifically supported processor based on the Cortex-A8: the Texas Instruments OMAP3530, the most powerful of the four OMAP35x SoCs that shipped last year. Ronetix also listed only one chip running the older Cortex-M3 core, ST's STM32 microcontroller.

The PEEDI's built-in “Flash Programmer” supports programming (via JTAG) of over 900 NOR flash devices, as well as 8-bit and 16-bit NAND flash devices, says Ronetix. Because PEEDI supports several flash profiles, developers can program a complete Linux system at once, including U-Boot, the Linux kernel, and the JFFS2 root filesystem, says the company.


The MIPS32, Cortex-A8, and Cortex-M3 firmware updates for the PEEDI JTAG/BDM Emulator and Flash Programmer are available now. More information is available here.
