SD-Card Insert Not Detected For Display Modules With SD-Slot, Marlin 2.0.x #12

Closed borland1 closed 4 years ago

borland1 commented 4 years ago

There is a fix now for Marlin bugfix-2.0.x (new issue #16224).

Problem: When file Configuration_adv.h is edited to enable display module SD-Slot...

if HAS_SDCARD_CONNECTION

define SDCARD_CONNECTION LCD

endif

This configuration enables SD-slot on display module, and disables Onboard SD-slot (except for bootloader on powerup to enable firmware updates).

Since both Display and Onboard SD-slots share the same SD_DETECT_PIN, only one SD-card can be used.
