Re: [microblaze-uclinux] Booting from system ace

[Michal Simek <monstr@xxxxxxxxx>]

Hi Nathan,

it is great you found where is your problem. Just remove all FLASH config from
petalinux config file look at include/configs/petalinux.h or similar.
There you have to remove flash specific commands. Just remove them and build.

About system.ace. You have two choices.
1. Use your own bootloader and copy u-boot from cf to ram and jump to start
2. incorporate u-boot.elf file to your ace.

It is up to you what you want to use.

Regards,
Michal
