I have a question on interfacing uart to uart issue:
I have my own BF533 based boards and I want to communicate between them via UART port.
How do I do that?
Will it suppose to work with connecting 3 wire cable? (RX to TX,TX to RX, GND to GND).
I have tried that and I get no data in my receive board.
I have configured the dma6 for receiving trough uart and dma7 for transmitting trough uart.
If I send data trough other device to the blackfin the data is received OK but from blackfin to blackfin, I get no data even no start of data.
Thanks in advance
