MSP430F5419: MSP430F5419 - Controller gets hanged

Vijeth K Shastry

Part Number: MSP430F5419

We have an application project where we collect data from many slaves connected in 485 bus using UART module.
after few iterations the controllers gets hanged at particular point. We are not able understand the excat reason for this.

Please find technical details below.
1) SMCLK - 16777216 Hz
2) MCLK - 16777216 Hz
3) Timer - COntinous mode - 1 ms interrupt.
4) UART - 19200 baud rate
- SMCLK

Kindly help us in resolving the issue.

This looks as if your program has called exit() or abort(). Check the call stack.

We are not calling the exit() or abort() function anywhere and no LPM mode entry is also taking place . Is there any occasion during which the controller decides to go to exit() or abort() call ?

A failed assert() could cause this, or simply falling off the end of main().

Again, check the call stack.
