STM32F417 UNALIGNED ACCESS

Question asked by kondratovich.fedor on Dec 19, 2016

Hello
Periodically, the program enters the HardFault_Handler. In the register HFSR set bit FORCED and in UFSR register set UNALIGNED.
The project uses STM32F417, FreeRtos, LWIP. In most cases, the error in the stack are LWIP function. The error occurs rarely once
a few days.
The program is compiled with the flag --no_unaligned_access.
It is unclear why there is such an error - while --no_unaligned_access flag is enabled and even every few days, and second whether it is possible to process or ignore
this error and continue the program?
