Hello ST Community,
I am working on a custom bootloader for the STM32G473CCU6 microcontroller to enable firmware updates via the USB DFU interface. I am using the STM32CubeProgrammer API v2.17.0 | Windows-64Bits.
The microcontroller has 256 KB of flash memory in dual banks, which is 128 sectors of 2 KB.
Flags: BFB2 = 0, DBANK = 1.
I need to erase sectors 1...125 and not erase sectors 0, 126, 127.
I am trying to do this with the following function:
int sectorErase(unsigned int sectors[],unsigned int sectorNbr, char* sFlashMemName = nullptr);
But only 64 sectors (0...63) from bank 1 can be erased. Sectors from bank 2 are not erased.
I tried using indexes (64...127) and (65280...65343)
DisplayCallbacks output when erasing sectors 1, 2:

The output says that "erase command correctly executed", but in fact no sectors are erased.
Does anyone know how to erase sectors from bank 2 using STM32CubeProgrammer API function sectorErase()?
Thank you!
