Programming

Since the board doesn't have a programmer on-board, you need to use your own and specify which one you're using in a custom openocd.cfg file:

# Replace this with your custom programmer
source [find interface/stlink-v2.cfg]

# If you use the clone CKS32F103C8T6 chip you need to overwrite this ID
#set CPUTAPID 0x2ba01477

# To select a specific programmer you can specify its serial number
#hla_serial "\\x53\\x3f\\x6f\\x06\\x50\\x77\\x50\\x57\\x12\\x17\\x13\\x3f"
# You can discover the serial via `stlink --hla-serial` or `st-info --hla-serial`.

Then include this file in your build options like so:

<library>
  <extends>modm:blue-pill-f103</extends>
  <options>
    <option name="modm:build:openocd.cfg">openocd.cfg</option>
