U-Boot no booting on CM3

Metatron2k2 commented 3 years ago

Description U-Boot of Hardknott Branch does not boot on CM3+ at all. U-Boot 2020.1 from Dunfell works as expected (after updating with @emilm 's Patch.

Setting uart_2ndstage=1 in config.txt reveals that the system stops after loading U-Boot

Steps to reproduce the issue:

Build core-image-minimal (with U-Boot) on hardknott
Write Image to CM3+
Try to boot.

Describe the results you received: Stuck on boot.

Describe the results you expected: Booting system.

Additional information you deem important (e.g. issue happens only occasionally): 2nd stage logs:

Guys, I do not know if this is the same issue I was facing, but u-boot did not work for me on kirkstone and I did the following to solve it:

Modify config.txt as follows:

remove all the unnecessary comments from config.txt (see explanation in https://github.com/raspberrypi/firmware/issues/1575#issuecomment-834790815) to strip it down to only a few lines of actual config
set dtoverlay=disable-bt to be able to use the UART properly for anything following after the second stage bootloader finished

Very interesting. Did you encounter this while using network booting? As far as the issue you are referencing is describing, it only applies to network booting.
