Enabling UART on GPIO?
Posted: Sat Jul 27, 2024 7:09 am
hi all
i'm trying to enable UART0 on cm3588. i have tried a variety of ways but am not getting anywhere.
i have tried enabling the entry in the DTS file to "okay" within /usr/src/linux-headers-6.1.57/arch/arm64/boot/dts/rockchip/rk358
8-nanopi6-rev09.dts but it doesn't help.
I have discovered that FIQ0 is the debug console which i have manged to boot into U-Boot but can't figure out if there are any parameters to include to enable UART.
There is another port enabled on boot at /dev/ttyS6 but that doesn't seem to be the correct serial port either.
Am i enabling it correctly? CAn anyone provide some guidance?
thank you
