Hello Eric!
I have an IBM ASH (NPe405h) board that I am trying to get U-Boot 0.4.0 running on. Ultimately, I'll port this over to our custom board that is very similar to the ASH, but I figured it would be better to start on a known platform.
Good idea!
I downloaded the new 0.4.0 U-Boot and ran these two commands (after modifying the Makefile to run 'ppc_405-' instead of 'ppc_8xx'): make ASH405_config make all
Sorry, but the U-Boot ASH405 target is an "esd" custom board (PPC405EP based) and _not_ the IBM Ash Eval Board! :-(.
It flew through compile and link to produce the nice u-boot.srec. I put that in my tftpboot directory, telnet'd over to the abatron 2000, erased ASH flash and programmed this new image in there.
The result is an immediate SystemError LED illumination.
I then switched from Flash to SRAM (one of the dips on the ASH board) and reloaded. Running from SRAM produces a program exception and jump to 0x700 almost right off the bat.
I am running out of ideas on how to get U-boot and my ash board to cooperate. Has anyone else that has tried this had the same problems?
I am afraid, but the IBM Ash Eval Board is not supported (to my knowledge) right now. I don't think, that a NPe405h target is supported at all. This should not be so hard starting from the PPC405GP.
Best regards, Stefan.
