IMX6D custom board, change debug port from UART1 to UART4

Hi,

We've developed a custom board based on the (SABRE Board for Smart Devices Based on the i.MX 6 Series Product Summary Page). The RAM is kept intact, however the pinout for peripherals has changed. We're booting from SD.

Currently we're not fully booting, but we'd like to move the default debug port from UART1 to UART4 first, we can't seem to find where to change this. Any help is deeply appreciated. After that we likely need help with the boot log.

Best Regards,

Peter Hygren

Hi Peter.

Did you manage to change the debug UART?

We need to change it from UART1 to UART2.

I saw there was some kind of patch back in 2012 to be be able to do this.

Best regards,

Niklas
