### Repo for all things RP2040.
[Get Started Guide](https://datasheets.raspberrypi.org/pico/getting-started-with-pico.pdf) | [Libraries & tools](https://datasheets.raspberrypi.org/pico/raspberry-pi-pico-c-sdk.pdf) | [Datasheet](https://datasheets.raspberrypi.org/rp2040/rp2040-datasheet.pdf)
Settings things up:
Flashing ST-Link V2 as Black Magic Probe. Follow this [link](https://ciesie.com/post/black_magic_probe_stlink/) or follow the steps below:
start OpenOCD:
```
openocd -f interface/stlink-v2.cfg -f board/the_board.cfg \
-c 'reset_config trst_and_srst'
```
Connect GDB to OCD:
```
arm-none-eabi-gdb --eval-command="target remote localhost:3333" firmware_binary.elf
```
Open the ST-Link v2 programmer and connect the SWD pins as shown below:
Clone Blackmagic git:
```
git clone https://github.com/blacksphere/blackmagic.git
```
Build it!
```
cd blackmagic
make
cd src
make clean
make PROBE_HOST=stlink
```
Unlock the memory before the programmer is flashed
```
openocd -f interface/stlink-v2.cfg -f target/stm32f1x.cfg \
-c "init; reset halt; stm32f1x unlock 0; reset halt; exit"
```
Erase the flash memory
```
st-flash erase
```
Update actual Black Magic Probe:
```
st-flash write blackmagic.bin 0x8000000
```
Write Firmware
```
st-flash --reset write blackmagic.bin 0x8002000
```
