Stm32 system exception is an interrupt, exceptions to these systems don't return NVIC tube (because I found behind the system the use of the systick timer process does not use NVIC), strives for the great god

CodePudding user response:

System anomaly points several terminals, data abnormal, abnormal code before the number of interrupt is abort

CodePudding user response:

Exception is interrupted, have interrupt entry such as hardFault_Handler, in assembly code * s [such as startup_stm32f205xx. S]
