Hi. When upgraded my RetropPIE 3.7 to 3.8 gpio_db9 stop working (no visible module, no joysitck). When installed new freshed img from main site and tryed to install gpio_db9 so i still have msg GPIO driver installation FAILED .
When trying manually install deb i have this :
Bad return status for module build on kernel: 4.4.11-v7+ (armv7l)
on 3.7 gpio_db9 working properly without problem, on 3.8 its not possible to install from RETROPIE-SETUP or manually. Any sollution ?
