These instructions are for linux. First, clone bumpy firmware
git clone email@example.com:electronut/blackmagic.git -b bumpy. Then
cd blackmagic and run:
src will contain the binaries.
To upload a specific version of firmware:
dfu-util -s 0x08002000:leave:force -D blackmagic.bin
We recommend using version v1.3 firmware, it has support for Nrf52840 and newer chip IDs for Nrf52832 etc., but automatic reset upon disconnect from GDB doesn't work in this one (though you can do
run inside GDB to run the code). V1.2 is here for archival reasons.
