Hello, I was hoping you could help me out with something. I just have 2 main questions. I am using a SAMA5D27 and I've managed to port AT91Bootloader and I'm currently on U-Boot
U-Boot SPL can bring SAMA5D2 up, you don't need the AT91 bootloader.
- I am trying to use FLEXCOM1 (UART) as the main console of U-Boot but
haven't been able to find any documentation saying where or how U-Boot specifies the console port.
$ git grep DEBUG_UART configs/sama5d2* configs/sama5d27_som1_ek_mmc_defconfig:CONFIG_DEBUG_UART=y configs/sama5d27_som1_ek_mmc_defconfig:CONFIG_DEBUG_UART_ATMEL=y configs/sama5d27_som1_ek_mmc_defconfig:CONFIG_DEBUG_UART_BASE=0xf8020000 configs/sama5d27_som1_ek_mmc_defconfig:CONFIG_DEBUG_UART_CLOCK=82000000 configs/sama5d27_som1_ek_mmc_defconfig:CONFIG_DEBUG_UART_BOARD_INIT=y configs/sama5d27_som1_ek_mmc_defconfig:CONFIG_DEBUG_UART_ANNOUNCE=y
would indicate there's a debug uart which you can use.
I'm adding atmel maintainer to CC and dropping dead contacts.
- When U-Boot tries to boot it gives me these errors:

NOTE: On my lists.c file I changed all the "dm_debug" for "dm_warn" because the debug uart is the only one that's responding. Any help or guidance would be really appreciated.
Seems like some drivers are disabled.
Which version of U-Boot do you use ?
What platform did you derive your configuration from ?
