Hello, I'm using a sama5d27 SoC and I've already port at91bootloader but now I'm having trouble with u-boot. When u-boot.bin finishes loading SD/MMC: Done to load image But then it says <debug_uart> No serial driver found resetting.... In my device tree I already defined my usart using FLEXCOM1. How do I redirect the debug uart into these usart? Or do you think this has to do with my device tree? atmel_usart.o does gets generated and the target is defined on the makefiles. Thank you, sorry if this has been asked before. PD: I'm not using any commercial board, is a custom one.
