It seems those devices would need to change from > 'uart5' to 'uart11'. Apparently the above configuration is bogus. I checked the schematic of the IDP which uses uart5, the debug UART is on pins 22 and 23, aka qup05. It seems uart5 works in spite of the bogus pinconf because the default for the pins is their QUP function.
