BB AI64 How to access u-boot

I am able to log in using USB C to USB and only get the login prompt. Unable to hold the space bar to get into u-boot or see the kernel messages.

Debian 11.3 emmc image

Is the USB C the correct port for linux debug?

Hello,

You will need a Debug cable in the debug cable port on the BBAI-64. At least, this is what I needed to handle jumping into u-boot.

Thank you Seth.

Hello @foxsquirrel ,

The adapter is an adapter on the three pinout connector (one of them) and a TTL to USB cable is needed.
