I am trying to activate the second serial port on the ns7520_a platform using NET+Works version 6.2. I have rebuilt the BSP setting BSP_SERIAL_PORT_2 to BSP_SERIAL_UART_DRIVER in bsp.h as directed i.e. #define BSP_SERIAL_PORT_2 BSP_SERIAL_UART_DRIVER but although this worked for version 6.0 it has had no effect with version 6.2. Can anyone say what I’m missing? Thanks
