New page

Started off using following guide:
https://medium.com/@paramaggarwal/programming-an-stm32f103-board-using-usb-port-blue-pill-953cec0dbc86

However, still didn't seem to work, always got following errors in dmesg:
<source>
usb 3-1: new full-speed USB device number 122 using xhci_hcd
usb 3-1: device descriptor read/64, error -71
usb 3-1: device descriptor read/64, error -71

usb usb3-port1: unable to enumerate USB device
</source>

Workaround was to first perform an erase step and follow it up with a verify just for good measure:
<source lang="sh">
python ./stm32loader -p /dev/tty.SLAB_USBtoUART -e ./generic_boot20_pc13.bin
python ./stm32loader -p /dev/tty.SLAB_USBtoUART -w ./generic_boot20_pc13.bin
python ./stm32loader -p /dev/tty.SLAB_USBtoUART -v ./generic_boot20_pc13.bin
</source>
Keep BOOT0=1 and BOOT1=0. Reset between each step just in case.

When resetting bot jumpers to 0 and resetting the fast/slow flashing worked and the device was seen on USB.

Make sure to verify the bootloader was downloaded and not just some HTML page.
