hi, so i've been using repetier-fw v1 dev (just updated to latest) on this setup (ruramps 1.3 + due) for a long time and everything was good.
for the first time tho, today i tried to use the SD Card through a common reprapdiscount smart controller. it does not work.
but it works in Marlin 2.0 bugfix so it's not a hardware problem either.
pin assignment appears correct and identical between marlin and repetier. i get no error messages in the log, just
17:55:05.869 : Begin file list
17:55:05.869 : End file list
any clues on what could be wrong? SDSUPPORT is obviously enabled in configuration.h, along with the SDCARDDETECT pin
