Hi @developerTirol
Can you please provide me detailed instructions how to reproduce the problem.
I took a Colibri iMX8X with default Linux installation, ran the SDK’s HelloWorld example from U-Boot and booted Linux from U-Boot - All working fine.
The HelloWorld expectedly doesn’t give output, because the debug port is mapped to the wrong UART pins. Still Linux is booting fine with this configuration.
Regards, Andy
