Booting with u-Boot #279

Closed doraemoncito closed 2 years ago

doraemoncito commented 2 years ago

Hi, I'm trying to run the example code from the samples directory in circle over TFTP using u-boot on a Pi4 and I'm finding that many of them hang / freeze. It I get u-boot to download itself over TFTP and run, it just works, e.g. u-boot happily boots u-boot so I'm working if there is something I'm missing during the compilation of the circle samples that might be causing this.

This is the console log output from u-boot when starting the gamepad sample:

Any suggestions?

Here is the complete boot log: u-boot-log.txt

Can you please send the kernel7l.lst file (in a .zip file), which corresponds to the stack trace above? Without it I cannot tell much. What is the quickest way, when I want to reproduce this here? Where can I get u-boot from?

rsta2 commented 2 years ago

I found a problem in Circle. You do not need to send anything. I will provide a patch soon.

rsta2 commented 2 years ago

There is an update on the develop branch, which should fix the problem. Can you please try it? Thanks for reporting the problem.

doraemoncito commented 2 years ago

Excellent work. That's fixed it!

rsta2 commented 2 years ago

Great! Thanks for testing!

rsta2 commented 2 years ago

This issue has been fixed in Circle 44.4.

Awesome, thank you.
