stm32f100xx not (properly) supported

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Boot STM32F100C8  into bootloader and connect via USB-2-TTL UART
2. run: stm32flash -c "/dev/tty.wch ch341 USB=>RS232 620" 

What is the expected output? What do you see instead?

Thanks for the report. For comparison, is there something that does work for 
you? Other chip, other OS or previous stm32flash version? You are aware that 
you have to run without the -c option the first time after the chip is reset, 
right?

Thank you for the fast reply!

I just realized that the 32.768kHz oscillator space on the PCB was empty, so I 
soldered something in I had floating around. And now this works - I have to go 
down with the speed quite dramatically:

stm32flash -b 9600 "/dev/tty.wch ch341 USB=>RS232 620" 
stm32flash 0.3

http://stm32flash.googlecode.com/

Serial Config: 9600 8E1
Version      : 0x22
Option 1     : 0x00
Option 2     : 0x00
Device ID    : 0x0420 (Medium-density VL)
- RAM        : 8KiB  (512b reserved by bootloader)
- Flash      : 128KiB (sector size: 4x1024)
- Option RAM : 16b
- System RAM : 2KiB

Resetting device... done.

Everything else works fine out of the box (well, had to update for stm32f030f4) 
- STM32F103C8, F103RB, F051, F407, ...

Sorry for the misleading bug report; obviously that cheap development board has 
some issues.

Thanks for clearing that up. The system bootloader uses the internal 8MHz 
oscillator (HSI), so I don't understand why the external 32kHz would make a 
difference.
