Debug tool targets PowerQUICC processor

Dec 15, 2008 — by Eric Brown — from the LinuxDevices Archive — 30 views

Ronetix announced the availability of new PowerPC firmware for its Linux-friendly JTAG/BDM emulator and flash programmer. The PEEDI JTAG/BDM Emulator and Flash Programmer now supports the Freescale PowerQUICC II Pro MPC83XX processor, says the vendor.

The PEEDI (“powerful embedded Ethernet debugging interface”) has previously supported Freescale Nexus-enabled PowerPC and ColdFire processors, but this is the first support for the PowerPC-based PowerQUICC II Pro. Other supported processors include ARM11, ARM7, ARM9, XScale, and ADI Blackfin.

The firmware supports both debugging and flash programming on PowerQUICC II Pro MPC83XX processors, says Austria-based Ronetix. The family includes the MPC8630E and MPC8349E processors, which are based on an e300 PowerPC core clocked at up to 667MHz. Aimed at high-end networking applications, the chips also include Freescale's QUICC networking engine, clocked at up to 500MHz. The QUICC engine offers hardware-accelerated support for Ethernet, ATM, POS, TDM, and other networking line protocols.

The PEEDI's built-in “Flash Programmer” supports programming of over 900 NOR flash devices and 8-bit and 16-bit NAND flash devices connected to a MPC83XX CPU via the JTAG interface, says Ronetix. Methods provided for ECC calculations, including bad block management and clean markers, are said to include hardware ECC using the MPC8313 NAND flash controller, standard software ECC for JFFS2, and ECC for YAFFS2. 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 PowerQUICC II firmware update for the PEEDI JTAG/BDM Emulator and Flash Programmer is available now. More information is available here.
