i.MX53 QSB U-BOOT

Postby ckhmer1 » Fri Dec 02, 2016 8:05 pm

Hi,
I've booted succesfully my i.MX53 Quick Start Board using Archlinux arm distribution build for USB Armory.

The only changes to do in order to boot are:

- compile the u-boot for mx53loco
- change the boot.txt in the boot folder and execute mkscr

It is needed to path the u-boot source tree before to build it using following patch file

The boot.txt I've used is:
