This turns out to be a misunderstanding on my side. Obviously you can't let two OS:es (Marlin, PC) operate on the same filesystem simultaneously. Therefore, access is exclusive at any point in time, and is given to the PC by sending the gcode M22. If I do that, the PC sees the SD card. Access can be given back to Marlin by sending the gcode M21.by mdjurfeldt - Firmware - Marlin

It's true that there are differences in the hardware profiles. But the error doesn't seem to be at the hardware level at all, does it? The card *does* present a usb storage device to the PC. It's just that that device has no medium.by mdjurfeldt - Firmware - Marlin
Hi, I'm a Marlin newbie. Yesterday, I configured and installed the HEAD of branch bugfix-2.0.x (commit 113af46) on an MKS SGEN v1.0. I used the MKS SBASE configuration for this. Everything seems to work, except that the MKS SBASE configuration is supposed to expose the SD card of the controller board to the PC via USB. But the USB storage device exposed to the PC says "no media found". The SDby mdjurfeldt - Firmware - Marlin
