#169 Flashing STM32F446 fails at 30%

[Stefan Riesenberger]

Hello!

I was trying this tool with my STM32F446 and it seems it doesnt flash properly. It just stops at ~30%.

Is there any logging I can provide? I have access to a logic analyzer, if that would be helpful somehow.

.\stm32flash.exe -b 115200 -w firmware.elf -v -g 0x0 COM12

Using the STM provided programmer tool works fine.

It seems that you are programming an .elf file directly onto the device. You should extract a binary file from the ELF file and use that instead.

Or .hex file.

ohhh that worked!
Thank you so much!

Sorry for bothering your with my incompetence...
