Current master fails to flash stm32f0discovery (stm32f051) #90

Closed maknoll closed 9 years ago

maknoll commented 9 years ago

it works on v1.6-rc0

i will test this on a native probe, but i assume it will be the same result.

Error writing data to flash

The flashstubs are compiled for M3. STM32F0 is a M0. Compiling the flashstubs for M0 makes it work again. I have some patches, including this one pending on https://github.com/UweBonnes/blackmagic.git

That makes sense, thanks! Do you wanna make a pull request?

Oh, sure :) I don't have the board here now, but i will let you know once i have tested it.

maknoll commented 9 years ago

I have cherry-picked your 3 latest commits an they solve the issue (actually the latest alone does, but i liked the other ones too).

Tested on a STM32F072, not tested on a M3, but since ARMv6 is a subset of v7 it should be allright.

@UweBonnes Thanks for the observation. This is fixed by #92
