YAMON does lots of board specific initialization, so when porting Linux to an Au1xxx that doesn't use YAMON, you are going to have to add to the Linux initialization functions for the board. U-Boot is a popular boot monitor that is now finding it's way to the Au1xxx processors. > ... Are bootloaders like YAMON position independent > to run out of SDRAM? Yes, they usually do that. -- Dan
