im using a custom carrier board, where uart0 is not connected,and uart1 is connected instead.
how do i modify uboot to use it as console?

i tried changing stdout-path
in 64_TX1\Linux_for_Tegra_64_tx1\sources\u-boot_source\arch\arm\dts\tegra210-p2371-2180.dts
also, in 64_TX1\Linux_for_Tegra_64_tx1\sources\u-boot_source\include\configs\tegra-common.h changed
CONFIG_CONS_INDEX.
that didnt work.

the uart does work as a linux getty, after changing extlinux.conf and kernel_source\arch\arm64\boot\dts\tegra210-common.dtsi

another question , why are the uart addresses different in the linux tegra210-common.dtsi and the uboot tegra210.dtsi?
