SPI SDcard not working with LilygGO T-Display

[bruno1950]

Hi, even if this issue was discussed as #32 three years ago in my hands still it is unsolved.
I've tried to use two different SD card modules that work perfectly on ESP32 and ESP8266 if the display used is an OLED connected through I2C.
When I use these same SCard modules with LilyGO they simply don't work and all the options I tried after carefully reading the discussion od the issue #32 were a failure.
According to the suggestion of the issue # 32 I tried the following pins CLK 25, MISO 26, MOSI 27 and CS 15 but whit this wiring and the code suggested the LilyGO starts rebooting continuously.
Since I'm a newbie, I'm at a dedline
Could you help me to solve this problem and show me whhere is my mistake ? Thanks in advance for your help
