Hello,
I was using the demo for MSP432.
I solved the problem this morning: I was not configuring the PIN P1 in the init_uart0() for the half-duplex, also I was not inicialiting any task or the scheduler, and a few minor other things.
Now I have another problem though: when I use a queue in the IRS routine for the UART it doesn’t read all the bytes. I suspect that the problem is that the queue is too slow for the baudrate (500kbps), but I’m not sure. If I use a global variable + flag it works fine though.
