Re: [microblaze-uclinux] Booting from system ace

Michal,

I'm able to download my u-boot.elf, but I still get no output on the
serial port.

I didn't see anything in include/configs/SX1000ds.h that talked about
moving variables to RAM. The references to flash appeared to be
appropriately undefined.

Thanks - I got insight running & talking to xmd/gdbserver on my board.
It downloads u-boot.elf, but gets stuck running before it hits main
(that normally brief period where it runs before hitting the
breakpoint at main). What's it doing in that phase? Initializing
memory?

I mentioned 10.1.3 just in case it was relevant.  Almost all my use of
EDK has been at 10.1, so I don't have context to compare its behavior.

It looks great. I am following it now (I know the gaps that you filled
seem trivial, but newbies like me have an art for falling into them!-)

Much thanks as always,
Nathan.
