Oh ok. My main problem is that I DO have debug_uart but I don't have U-Boot main console. I already have the configuration on my defconf for the debug UART like this: CONFIG_DM=y CONFIG_DM_SERIAL=y CONFIG_DEBUG_UART=y CONFIG_DEBUG_UART_ATMEL=y CONFIG_DEBUG_UART_BASE=0xf8038200 CONFIG_DEBUG_UART_CLOCK=58000000 CONFIG_DEBUG_UART_BOARD_INIT=y CONFIG_DEBUG_UART_ANNOUNCE=y I cloned from the github repository *https://github.com/linux4sam/u-boot-at91 <https://github.com/linux4sam/u-boot-at91>* My configuration was derived from the sama5d2_xplained board because I'm working with a custom one.
