Posted on November 17, 2016 at 10:35Hello everybody,
I'm actually working on a bootloader on an STM32F030X8 board. The programme already work's on a L100RC and an F303RE.
My bootloader starts at 0X08000000 ans my user app starts at 0X0800FA00.
I need to eraser before writing so here is what i do :
for(i=pStartAdress_u32;i<pEndAdress_u32;i+=1000)
{
halFlashPageErase_v((u8 *)i);
}
with start = 0x0800FA00 and end = 0x0803E800
the + 1000 is because page size is 1KB
then hal calls drivers with this function :
void drvFlashPageErase_v(u8 * pAddress_u8)
{
HAL_FLASH_Unlock();
FLASH_PageErase((u32)pAddress_u8);
HAL_FLASH_Lock();
}
My probleme is when i call this my programme blocks and my stack shows this :
Thread #1 (Suspended : Signal : SIGINT:Interrupt)
0xfffffffe
<signal handler called>() at 0xfffffff1
0xfffffffe
<signal handler called>() at 0xfffffff9
