UART 232

Connect TX/RX PIN connector to the UART 232 port on J31. From terminal run minicom:

minicom -s

Disable Hardware Flow Control and set Serial Device to /dev/ttySTM3. Check that characters typed from keyboard are echoed in the terminal.

UART 485

Tested /dev/ttySTM1 with another RS485 device. Configure minicom:

minicom -s

Configure the Serial Port Setup as shown:

RS485 minicom config

Wi-Fi

ifconfig end0 down
echo "nameserver 8.8.8.8" > /etc/resolv.conf
insmod /lib/modules/6.1.82/extra/mlan.ko
