I have an AeroCore2 carrier board which mates with TX2 module. One of the uart ports on AeroCore2 is connected to /dev/ttyTHS3 on TX2. As a test, I looped back TX/RX on AeroCore2 and typed the following on a terminal:
echo "testing port" > /dev/ttyTHS3
On the other terminal, I did:
I do not get an data on this terminal. I also noticed in DTS, “dma-names = tx” only not “dma-names = rx, tx” - do I need to add “rx” in dma-names ??
Please advise how to test ttyTHS3 port.
