Hi,

I am using STM32f429 disco FW_upgrade code as bootloader for my application. I had seen it erase only 11 sectors (1MB) of flash memory. I want to erase upto 23 sectors from my application address, So i have modified the code as below. But it hangs on fault handler.

/* Erase Flash sectors */

startsector = FLASH_If_GetSectorNumber(Address);

sectorindex = startsector;

/* Erase FLASH sectors to download image */

while ((erasestatus == FLASH_COMPLETE) && (sectorindex <= FLASH_Sector_22) && (HCD_IsDeviceConnected(&USB_OTG_Core) == 1))

{

erasestatus = FLASH_EraseSector(sectorindex, VoltageRange_3);

sectorindex += 8;

}

if ((sectorindex != (FLASH_Sector_22 + 8)) || (erasestatus != FLASH_COMPLETE))

{

return 1;

}

else

{

return 0;

}

The index is not enumerated linearly.
