Serial console to see u-boot logs etc
Posted: 03 Nov 2023, 15:25
Hello everyone,
We are trying to add the revpi-connect-4 to the BalenaOS project. During development sometimes its easier to see the boot logs and know what is wrong so do you guys know of way to see logs from these devices?
Are there some uart pins that can let us see these logs?

Edit-1: It looks like BalenaOS does drop into a tty login prompt when the hdmi is connected. For production images it shows a splash screen and we can get a tty login prompt by pressing some keyboard shortcuts. But this is probably after the linux kernel have booted.
