Howdy, I have a PowerPC 405GP Walnut eval board. Recently, by accident, the flash which stores U-Boot is corrupted. Therefore the board cannot boot now. I want to use the JTAG port on the board to rewrite the flash with new U-Boot. I found many products for this propers, but they are too expensive for me. It costs $1000-$3000... > _ < Eg: BDI2000, Silicon Probe... What I really want is

I'm getting to work on a PowerPC-based NAS appliance, based around an MPC8241 micro. There appears to be a standard 16-pin COP port on the board. Apparently nobody else in the entire universe has ever used this port, though. I have a (genuine Macraigor! Accept no substitutes!) JTAG wiggler that was originally bought for ARM development, and has the standard 20-pin ARM header. However, the ...

Ah, Saturday. Time to sit down and play with this PowerPC board. I installed a series resistor so the COP port on the board is supplying IO power (3.3V) and fired everything up. But Commander gives me the dreaded 03; cable disconnected error. If I query registers, I get either all 0s or all 1s (randomly, it seems). The only thing I can do is reset - that DOES work, so I know the interface ...

Many years ago when dinosaurs roamed the earth, there was the x86 and then there were the viable contenders. That list was headed by MIPS and PowerPC with others as "also ran". With time none of these architectures kept up with the megalith Intel's forces and the x86 took over the world resulting in the extinction of the dinosaur. In more recent times the focus has shifted from raw po...
