flashing external SPI Flash with STM32CubeProgrammer

MOtto.1 · ‎2025-05-13

Hi, i have recognize some odd behavior inside the CubeProgrammer external flashing feature.

When flashing files less or equal to 128KB, then it flashes size at boundary of the block size of the Flash device which is 64K. As soon i get bigger than that it no more send data in that boundary but 67072 bytes. Why is that? I had to rewrite my APIs to get that working properly. I mean it is working now but sounds strange too me.

Thanks
