SDCARDDETECT

srader18

I apologize if there is already a forum on this but I couldn't find it. I am trying to reflash my Monoprice Select V2 but when I go to compile the firmware I get an error with my SDCARDDETECT.

Error message: Arduino: 1.8.8 (Windows 10), Board: "Sanguino, ATmega1284 or ATmega1284P (16 MHz)"

Error compiling for board Sanguino.

No, sdcarddetect is not the problem. Check HAL.cpp line 662 and replace it with this

volatile long __attribute__((used)) stepperWait = 0;

it seems this solution works better. Compiler optimized the variable away.
