We want to switch to the powerpc platform but it doesn't seem to work. After the bootloader (tested with the uboot 1.2.0 and 2009.08) starts the cuImage.lite5200 it doesn't show anything in the console. I'd like to know if the lite5200b is still supported and which version is known to work with it and what is the default configuration. I want to test it like the developers do, until I configure it myself. I've managed to do some debugging in assembler, to know that it works properly until DCACHE is enabled in setup_common_caches of arch/powerpc/kernel/cpu_setup_6xx.S. If I skip enabling the DCACHE it continues properly until the MMU is enabled. I'm only debugging it writing to the serial port registers in assembler, so I'm not very sure if it continues properly or if I am not able to debug it after the DCACHE is enabled or the MMU is enabled. I want to debug it with a JTAG debugger, but I still don't have one (do you recommend me anyone?). Kind regards and thank you for the help, Asier
