Hi to all, Finally I got my mpc8272ads board running the 2.6.20-rc1 kernel. The trick was:
First, I had to comment out the BCSR modification for second UART in m82xx_board_init function (arch/ppc/platforms/pq2ads.c). As suggested by Dan Malek, MMU is still off at this point. Second, the uboot bootargs must be modified from those used for kernel 2.4. Now, the selected console has to be ttyCPM. This was unnecesary in kernel 2.4, as correct console was selected by default. Best regards
