Hi, I have a powerpc P2041 board which runs a u-boot successfuly when the u-boot is located at the 0xFFF80000 address of the flash. I want to place the u-boot in 0xF0000000 address as 0xFFF80000 will already be used by another software. I changed the address in the config file. Then I connect the board with a debugger and change the program counter (PC) to 0xF0000000. I expected to see the u-boot messages in the serial port but saw nothing. I thought this could be due to a tlb problem. So, I first added the 0xF0000000 address in the tlb range with another little program then jumped to the 0xF0000000, but the result is still failure. So, how come can I configure the u-boot so that it will be able to run at 0xF0000000 address. Any help is really appreciated. Thank you.
