Just started tonight with the STM32 on a generic "blue pill" board for building up a STEM school project for my wife's school.
Most things are working brilliantly. Much appreciated the effort put into this.
Using Arduino 1.6.5r5 64-bit on Ubuntu 14.04LTS on my laptop.
USB to blue pill works nicely.
"./stm32flash -w ~/src/repos/STM32duino-bootloader/STM32F1/binaries/generic_boot20_pc13.bin /dev/ttyUSB0"
Then after attaching usb-micro cable; disconnecting usb/serial foo; and, reprogramming a sketch (a pc13 blinker) when restarted, no problem, but further reprogramming is not possible. It hangs at this point:

Does anything have to be in the sketch to ensure it can handle the next upload, or is there something else I'm missing. Hmmm, I think I'm using head from the repo which may be an issue perhaps?
Any suggestions would be most welcome to this STM32 newbie.
Thanks again and kind regards,
