You don't initialize sFilterConfig to zero, so sFilterConfig.FilterMaskIdLow could be a random number upon POR.

Adding the the pull-up on the Rx line is no different from the Tx on the other board being set to high, once the UART is initialized. So it's a race condition as I mentioned before. When you disconnected the other board, the Rx isn't being set to hig...

Nevermind, it's over your head.

Sounds like a race condition. The Tx output is a pull-push type so you wouldn't need a pull-up on the Rx line. So i'm guessing that your Transmitting board must be powering up at the same time as the receiving board but hasn't set up the Tx pin befor...

When posting code, use the code sample which formats it and makes it easier to read the code. You need to post the rest of your code so we can see how you're enabling the UART interrupt and what you're doing the callback
