Is Juno soc_uart1 only available in secure state ?

Stefan

I've been trying to use the soc_uart1 on the Juno board the same way as soc_uart0, but there seems to be a problem with this.

Some files in 'arm-trusted-firmware' hint that the uart1 is only available in the secure world. Can I change this and use it as a non-secure uart ?

Thanks,

Stefan

    So, the details in /arm-trusted-firmware/plat/juno/bl1_plat_setup.c would be

    Replace

    "~SOC_NIC400_BOOTSEC_BRIDGE_UART1"

    with "~0"

    Build bl1.bin and copy to configuration microSD card .../JUNO/SOFTWARE/

    and then you can flood UART1 with non-secure prints.
