This may be of your interest:
https://github.com/GBert/openwrt-filesThe PIC programmer is used to program a PIC18F microcontroller, which could be used for hard realtime
stuff or get other peripheral connected (e.g. CAN, RS485 etc) to your Carambola. A sort of Big/Little concept:
Carambola CPU and a little MCU.
The intention is not another PIC programmer. I just wanted a CAN interface and doing other things without
the need of a separate programmer even on updates of the PIC code.
If you want to waste some spare flash on your Carambola you could even use to write code
for your PIC18 direct on your Carambola. Just install jalv2 if you like to (script/feeds install jalv2).
