Other Parts Discussed in Thread: MSP430F249, GRACE, MSP-FET, ALP
Hi, We have a custom in house board with MSP430F249 controller. The System occasionally halts in the boot/startup process. I can connect to target and load symbols to find out where the system halts. the PC stuck at 0xE8C and 0xE90,anding contents of Port_1_2_P2IN with 4 . Manually chaning PC to the next line results in various other controls of the pin and system can not boot. This halt error occurs in random in some of the cards.
I tried watchdog halting in _system_pre_init but IMHO the code stucks before pre init sequence.
Does anyone have similar experience regarding MSP430 boot issues or can someone with ROM bootloader experience point out relevant resources to examine and tackle the issue?
Thanks in advance.
