Did I break my stm32f103?

[mrburnzie]

Hello!

I'm new to the stm32 world and I've chosen the stm32f103 blue pill... at first everything was working I was using uart programming setting the BOOT0 to 1 and BOOT1 to 0 and using stm32flash (on linux) to flash the code and everything worked...
But suddenly the writing was really, really slow and going up to 56% and stopping... I think it's because I've somehow erased the bootloader? I admit I was changing the jumpers a bit...

Any suggestions on fixing?

Thanks!

The problem was that I wasn't flashing .bin I was flashing .elf files... my apologies

For what it's worth, I don't think it's physically possible to erase the bootloader. The worst you can do is set the top level of read protection in the option bytes, which is an irreversible operation that disables the debug interface completely. Do that and the chip is scrap.
