In order to make it easier for others to upload software, I decided to add the HID Bootloader:
https://github.com/Serasidis/STM32_HID_Bootloader
it is small and effiecient
uploaded this to Bluepill (both jumpers in "0" position)
$ ./STM32_Programmer.sh -c port=SWD -w ~/Downloads/stm32_HID\ bootloader2.2/F103/low_and_medium_density/hid_generic_pc13.bin 0x08000000

In order to test it, I uploaded "blink" using Arduino method "HID bootloader 2.2"
it worked, the device started blinking - tried again, but was unable, no matter what I did the HID device 1209:BEBA does not appear anymore.
Re-uploaded the bootloader using SWD - but this time it does not work at all.
I repeated this two times, this process does somehow mess up the device.
Solved! Go to Solution.

oh, I see, the main program gets executed first, unless I move the jumper!
Are there other small bootloaders ?
