I don't see that commit in u-boot-tegra. I assume it's in u-boot/master (TOT)? I'll try a Seaboard build from u-boot/master when I get a chance.

What about other (non-Tegra) ARM boards?

Hi Tom,

I can't boot mainline on seaboard at present without reverting this commit:

c50afc1d Revert "arm: armv7: add compile option -mno-unaligned-access if available

Is there supposed to be another way of fixing this, or is my toolchain broken? I may have missed something.

Regards, Simon

You mean you need to revert the revert to get U-Boot to run, correct?

As per our IRC discussion, I understand the board just hangs, so I suspect an exception in SPL, as all exceptions handlers there basically branch to themselves.

I'd like to know if the board did work between c50afc1d and now, for at least some commits, or if it never ever worked since c50afc1d.

Also, if running the board under JTAG debug is possible, I suggest doing so while making sure you'll get control if an exception occurs. This should tell us which exception occurred and hopefully where and why.

Regards, Simon

Amicalement,
