Well, definitely not all cases are fixed. I can’t boot now after installing the firmware-upgrade package. Installation went without errors. And now boot stops at
DDR3 training sequence - 2nd boot - skip
And that’s all. I’m now trying to boot over serial. Kwboot from Ubuntu 20.04 repo didn’t work at all. I downloaded the cz.nic binary build and that seems to do something, but so far all attempts at booting from kwboot failed somewhere in the middle. Is it possible that the watchdog is killing the router in the middle of u-boot upload? I tried the higher speeds, but the practical result is always the same.
What to do next, @miska?
