Re: [microblaze-uclinux] Still searching SystemACE bug

[Paul Hartke <phartke@xxxxxxxxxxxx>]

I'll mention again that the only time I've seen this work is when the
acefile contains both the FPGA bit file and the elf that starts the
processor is loaded from the same acefile.  Unfortunately it seems that
SystemAce and/or the Linux adapter code has some peculiarities.  Have you
tried this?

Are you using a bootloader to accomplish this?
"Please note that CF currently works when I copy image.bin ffrom CF to
ram, but not after linux has booted."

If so, in my experience that will NOT work.
