=== Dumping Firmware ===
Works with https://github.com/racerxdl/stm32f0-pico-dump (See SWD pins in top table)
=== Unlocking SWD ===
<codesyntaxhighlight lang="bash">
openocd -s $(pwd) -f interface/stlink-dap.cfg -f target/stm32f0x.cfg
telnet localhost 4444
reset init
stm32f0x unlock 0
flash erase_address unlock 0x08000000 0x10000
</codesyntaxhighlight>
:: Power cycle & reconnect st-link
<codesyntaxhighlight lang="bash">
flash write_image /path/to/dumped_firmware.bin 0x08000000
reset
</codesyntaxhighlight>
=== Dumping Running RAM ===
