Install OpenOCD

Follow Adafruit's excellent indstructions found here, until the point saying That's pretty much it! There might be a simpler way, and if so, please post a pull request.

Prepare OpenOCD for IR01

1. Change the SWD pin numbers:
   sudo nano /usr/local/share/openocd/scripts/interface/raspberrypi2-native.cfg
2. Find bcm2835gpio_swd_nums and change to bcm2835gpio_swd_nums 11 8
3. Find and uncomment bcm2835gpio_srst_num and change to bcm2835gpio_srst_num 4
4. Exit: ^x

Flash bootloader to CS11

1. Insert the CS11 using two connectors (1x small and 1x large) as per the image above.
2. Create a suitable folder:
   cd ~ mkdir bootloaders cd bootloaders
3. Download the CS11 Bootloader:
   wget https://github.com/xinabox/XinaBox-Bootloaders/raw/master/CS11/cs11_bootloader.bin
4. Download the CS11 Config file:
   wget https://raw.githubusercontent.com/xinabox/XinaBox-Bootloaders/master/CS11/openocd.cfg
5. Run OpenOCD:
   sudo openocd -f openocd.cfg

Flash bootloaders to other xChip Cores

1. Go to the section above and replace CS11 with name of xChip Core.

Notes

The OpenOCD you install will be the latest one, and the associated openocd.cfg might be out of date. You might need to change some parameters. If you do so, please don't hesitate to fire of a pulle request.
