We are using HC11E1 processor in our device which has LCD display and supports HART communication. There is a database stored in the NVM memory. We are facing a problem when we add a new data item to NVM database. The same code works absolutely fine on emulator without any problem. But when it is put in PROM, the device doesn't work. It displays nothing and also communication doesn't work. We are unable to know whats happening in the device code. We have tried erasing the NVM and loading it again, but this didn't help.
Can anybody help about this?
Thanks in advance!
