Hello Jace, thanks for the fast reply. The CPU19 bug would affect only the MSP430F248 , the MSP430F148 errata does not show the issue. Can you confirm that the MSP430F148 does NOT have this bug? We have two different boards (same pcb, different uC), both have unexpected resets. The F248 board could be affected due to the CPU19 bug. If the F148 does not have the bug, I need to keep searching. Currently I'm trying to reproduce the CPU19 bug in a minimal asm project to check if my results on the stack match the results of the CPU19 bug. Best regards, Lo
