Re: Help with custom bootloader

Hi @razzil, I think you should compile the second sketch using VECT_TAB_ADDR=0x800FF00, did you do it?

Re: Guide for under- and over-clocking the blue-pill needed

[...] and that version does not have a CLI, or take binary files (arrrgghhh) Hi Roger, just checked and it seems the STM's DFU has a CLI. It's named "DfuSeCommand.exe" and it's located in the same path of the "DfuSeDemo.exe". Need to understand how to use it.. [EDIT] maybe also ...

Re: STM32F103ZET6 support

Great!! Thanks! :o I think the 10ns sram there is an overkill, 55ns would be enough, and much more cheaper. It can execute out of external sram, afaik.
