The CR20 Pro comes with a BLTouch and 12864 mini clone. I use Marlin 2 bugfix and can either get the screen to work, then no uSD card access, or uSD card but then no screen. Common setting

define SDSUPPORT

For the screen to work you need to set //---------------------------

define MKS_MINI_12864

define LCD_CONTRAST_MIN 160

define LCD_CONTRAST_INIT 180

define LCD_CONTRAST_MAX 240

and

define SDCARD_CONNECTION LCD // LCD

Now the screen works but no SD card access //------------------------------ If however, you change

define SDCARD_CONNECTION ONBOARD

The screen does not work, but you have access to the uSD card. Is it possible to have both available as upgrades for Creality CR20 pro. I have silent steppers, with BLTouch, Neopixels, etc working but need a display and SD .. If I use a stock Creality from my Ender/CR10 everything works, as well as SBase 12864,, but the Creality mini 12864 is problematic.

Hi Creatron, the problem is still with my Ender3 stock LCD and SD card. I am using SKR 1.4 Turbo here. Can you tell me hows your CR10 LCD and sd card are working together?

I submitted a bug on Marlin, but it is not yet accepted, they did change some code but it still did not work. I can however send you my solution to try with no guarantees.
