Has anybody used this application PICKLE https://wiki.kewl.org/dokuwiki/projects:pickle with a Raspberry Pi 4 Model B?
PICKLE is an application developed in "C", which allows the RPi to use its GPIO pins to program a .hex file in a number of PIC microcontrollers
I can install and run the code, but the GPIOs do not respond correctly (PICKLE has a 'ptest' command that allows you to toggle the GPIO specified in a .pickle configuration file)
I know that the GPIO pins are working because I can toggle them with the standard 'echo 1/0' approach. I suspect the problem I have is with a driver called gpio_bb -- has anybody used this driver?
Some additional info
