Hi,

Thanks for your reply.

            Actual YAMON doesn’t have support for KMC board, hence we modified yamon source code according to the KMC board. Now we want to put our code into FUJITSU flash memory for testing purpose and  previous boot loader cmon has to be protected. After power on the board, instead of cmon we have to run our modified Yamon.

            CMON is executing perfectly, is there any possible way to go directly to the new boot loader code directly. i have some idea, is this approach will work

-          if we set environmental variable “start” as “go new_address”, will it go directly to the new bootloader in the next power-on.

-           Mips atlas board has jumper  which will redirect accesses from “Bootcode” range to either “Monitor flash” (0x1e000000) or the upper 4MB of “System flash” (0x1dc00000) based on jumper settings. if my kmc board have some jumper like this, can I redirect the start address.

Thanks in advance

 Regards,

Lucky
