Hello all

I am use the USB flash upgrade  in the discovery in my boards ;

where  the user code starts at 0x8008000

in some boards about 10%  the usb flash upgrade does not work ; after debugging we noticed that the sector erase always return the error FLASH_ERROR_PROGRAM;

    erasestatus = FLASH_EraseSector(sectorindex, VoltageRange_3);

Could you please guide me to find the reason to solve my problem

Hi,

Did you tried to use the ST-Link Utility tool for Flash erase?

You'd really help if you provide more details about your environment and your complete code.
