SKR1.4 Turbo, RepRap full graphic controller and NO SDcard (no replies)

Hi,
Ihave upgraded the version of MArlin to 2.03.9 and I can't read my SD card from the LCD.
Below are the different options I have selected :
#define SDSUPPORT
#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER
#define SDCARD_CONNECTION ONBOARD
#define SD_IGNORE_AT_STARTUP

My Marlin doesn't detect a SDcard inserted into the LCD slot.
I can upgrade the firmware from the SDcard slot on the board, but that's all.
With the older version of Marlin it worked well, I could read any SDcard from the LCD.
I'm sure I'missing something, but what ???

Please help
Regards
Thierry
