bl2 with bigger size for a boot loader

Unread post by tolonuga » Mon Feb 03, 2020 1:28 am

Hi, I'm trying the new boot/loader as a replacement for u-boot. It is basically a linux kernel and uroot combined with a bit of glue code.

However I'm hitting the 1MB limit of the BL2. The one I use comes from branch odroidxu3-v2012.07 from https://github.com/hardkernel/u-boot repository.

Is there a version that supports bigger images? Ideally even one that supports a variable size, so it can be as large as I need it to be?

Thanks, Andreas

p.s. in case you are interested, uroot is a userland for booting, written in go, see https://github.com/u-root/u-root. boot/loader is a set of patches for odroid-xu4/hc1 to make it boot this, with a small init loader (as uroot is too big). boot/loader was presented as patch series here: https://lkml.org/lkml/2020/1/30/221 and had a talk on fosdem here: https://fosdem.org/2020/schedule/event/ ... inux_only/
