Update Marlin 1.1.8 to 2.x LCD&SD problem

Dears,

I have a Tango board with REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER that works fine with version 1.1.8
Now I install the version 2.0.4 and 2.0.5:
first of all the LCD doesn't work with REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER but works with REPRAPWORLD_GRAPHICAL_LCD
with a SD init fail.

If I remove the SD card the LCD check correctly the remove and viceversa the insert of CD card is correctly identified, but there were a media non present
message. By serial monitor of Arduino the system said SD Init Fail.

Do you have any idea?

I have double check the pins files with the same parameter. Probably the errors are in some other file...

Well the first question that comes to my mind is what LCD do you actually have?
Pictures?

Hi, the LCD is
BIG TREE TECH reprapdiscount full graphic smart controller 12864

Hope this can help to find out a solution

Thanks in advance.

Newer marlin pushes the speed of the LCD as much as it can.

the BTT Graphics lcd is considerably slower than real RRD Graphics lcd's

Give this a try

In Marlin/src/lcd/dogm/ultralcd_DOGM.h

find U8GLIB_ST7920_128X64_RRD

and replace with U8GLIB_ST7920_128X64_4X_HAL

And set back to REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER

Dear,

first of all, thanks a lot for your suggestion.
The change works fine to remove the artifacts, and the LCD shows the infos correctly.

The problem of SD card reading remains, I have tried to change some parameters without any
improvent:
I have checked the #define SDSUPPORT is correctly active
I change the definition to #define SD_DETECT_STATE HIGH
I also change to line to #define SDCARD_CONNECTION LCD
noany combination seems working.

I insert the SD, everytime the LCD shows media insert, but when I enter into the menu to
find the file, the last line said media not present. I have tried also the change of SD card.

Tring ring again sometimes the media is shown correctly, seems randomly.When I remove it
and reinsert it doesn't appear correctly.
I have no idea how to find out a solution.
