I want to have simulated DRAM, so yes. But I will make it start always at 0 which removes one item. > >> +#define CONFIG_SYS_PROMPT "=>" /* Command Prompt */ > > this file has a bunch of "#define<tab>" where it should be "#define<space>" OK, fixed. > >> +#define CONFIG_LMB > > i dont think you need this either ? No, removed. Regards, Simon > -mike >
