# Flashing with pyocd
|
|
|
|
This is a different approach to flash the firmware on the b-parasites. It is completely optional.
|
|
|
|
## Basic instructions
|
|
|
|
(Based on the discussion in issue #67)
|
|
|
|
The instructions will probably differ slightly depending on your debugging probe and hardware setup.
|
|
|
|
The setup is fairly straightforward and documented in the `pyocd` [docs](https://pyocd.io/).
|
|
|
|
I used an inexpensive debugging probe from Aliexpress called `nanoDAP` from `Muse Labs` which is less than 10 € and readily available. The J-LINKs are hard to get and quite expensive. In my understanding basically all `CMSIS-DAP`-compatible probes which are recognized by `pyocd` should work.
|
|
|
|
After connecting the debugging probe via usb and connecting the b-parasite as described in the wiki, flashing was easy and fast.
|
|
|
|
For a complete flashing of softdevice and firmware use the provided python script. Assuming you put the `*.hex` files in default locations it boils down to one simple command:
|
|
|
|
```
|
|
python ./flash_firmware.py
|
|
```
|
|
|
|
For help and documentation of the available command line flags use
|
|
|
|
```
|
|
python ./flash_firmware.py -h
|
|
``` |
