Tool/software:
Hi,
We are trying to use UART1 (main_uart1) and UART4 (main_uart4).
For that we modified the "k3-am642-evm.dts" file available in the path "ti-processor-sdk-linux/board-support/ti-linux-kernel-6.6.32+git-ti/arch/arm64/boot/dts/ti"
But while echoing the serial port using the command "echo "hello" > /dev/ttyS1 and echo "hello" > /dev/ttyS4 " no output observed.
we used this command for the verification "sudo picocom -b 115200 /dev/ttyUSB1" and "sudo picocom -b 115200 /dev/ttyUSB4".
k3-am642-evm.dts used:
