Forum Post: MAP_AES256_setCipherKey locking up in MSP432

Hi, What sorts of things might cause MAP_AES256_setCipherKey() to never return? I can run the example no worries, and in the bootloader on our hardware, which then calls the main code, but then in the main code it freezes in the call to MAP_AES256_setCipherKey() on the following line: // Wait until key is written while (!BITBAND_PERI(AES256_CMSIS(moduleInstance)->rSTAT.r, AESKEYWR_OFS)) ; Any reason this can't be written by the bootloader and then the main code with a reset in between or something? This happens on both Rev B and Rev C versions of the MSP432, using Driverlib 3.50 and CCS 6.2.0. Regards, Josh
