Sorry to bother you again. I have a similar issue here. ?The TNC does cycle up nicely and no errors when flashing either the stand alone or the Raspberry version.
However, i can get get the paramaters to read. Now i have board version 2 which has 2 rows with each 4 pins to set the comm's. See the pic.
Can't make head or tails where to put the jumpers.
Thought i have them corrrect. I can see a serial port1 in /dev.
But it just keeps retrying.
Cold you help me ouit ?
