Part Number:MSP430G2553
Hello,
We are using MSP430G2553 for RFID reader application. Firmware provided by Ti for MSP430G2553 + TRF7970A is used as reference.
The tag details read will be updated through BLE (TI-CC2650) and hence a UART communication is set up between the two ICs.
Apart from the firmware provided from Ti, what is additionally implemented is saving tag details in Info segment of the MSP when BLE is not connected to its client.
While writing and reading the data from the Info segment, care is taken that the program is not going beyond the Info segment address.
But, we are facing an issue with MSP that is, it stops functioning all of a sudden. We doubted if writing to Info segment is done beyond the boundaries but, we are verifying the address each time a write operation is to be performed. When we try to debugging the IC again after the issue, we see that Info segment data is persistent.
Any chance the program counter is getting disturbed? Or any other things we can verify to solve this issue?
Any suggestion is very much appreciated as we are completely clueless at this point.
Thanks,
Maddineni
