First of all, I am sorry for my poor english. I have mpc850 custom board with followings:
SMC1 - console SMC2 - uart SCC2 - ethernet I want to use SCC2 and SCC3 as ethernet(two ethernet interfaces). As many web sites and mailing lists describe, I knew that SMC patch is required because SMC1 and SCC3 share parameter ram. I have DENX 2.4.25 kernel and this kernel works fine except using SCC3 as ethernet. When apply "USE_SMC_PATCH" in arch/ppc/8xx_io/micropatch.c, kernel hang and reset without any messages.(using u-boot 1.1.4) I want to know that when I use "USE_SMC_PATCH", which source file is modified and how to modify source file to use SMC1 as console. Could you tell me useful information about that?
