Hi

I am trying to communicate to BCM20737 tag board with peripheral uart. I initialised the puart using frunction tw_puart_init() from puart_control sample.

Also what I send to PC using puart_print is displaying correctly. So I think the setup is correct.

The problem is that the byte value obtained from puart_read() is not what I am sending from my PC. What can be the reason for this behaviour.

Thanks in advance.

I'm not sure what the reason is for the behavior you're describing, however, I do encourage you to use the sample code attached the following post to implement your PUART interrupts+reads:

Connecting an external board to the BCM2073X via the PUART

Interrupts + reads from the PUART can all be outsourced to prewritten functions in ws_upgrade_uart.c as you'll see in the code.
