load image not work when i use sd card

[andromeda92]

Hi,

i use teensy 3.6, esp8266 and TFT FT813 newhavendisplay.

the code jpeg.ino work well but when in an other programer i use SD card, for example SD.begin ... it don' work

the code below not work:

GD.begin(GD_STORAGE);

 delay(1000);
 // initialize serial for debugging
 Serial.begin(115200);
 delay(10);
 // initialize serial for ESP module
 Serial5.begin(115200);
 delay(1000);
 //GD.__end();
 Serial.print("Initializing SD card...");
 if (!SD2.begin()) {
   Serial.println("initialization failed!");
   return;
 }
 Serial.println("initialization done.");
 //GD.resume();
 loadFileToFT813();
.....


void loadFileToFT813()
{
 GD.cmd_loadimage(0, 0);
 if (!GD.load("tree.jpg")) GD.alert("file not found");
 GD.Clear();
 GD.Begin(BITMAPS);
 GD.Vertex2ii(0, 0);
 GD.swap();
}

i have tested with end and resume and is a same, it not work, but when i don't use

Serial.print("Initializing SD card...");
 if (!SD2.begin()) {
   Serial.println("initialization failed!");
   return;
 }
 Serial.println("initialization done.");
....
it work!

the declaration of SD2 is

#include <SPI.h>
#include <GD23ZU.h>


SdFatSdio  SD2;

.....

Any idea ?

thanks for your help.

resolved, this work.

void loadFileToFT813(String fname)
{
File file = SD2.open(fname.c_str());
GD.begin(0);
if (!file) GD.alert("file not found");
GD.cmd_loadimage(0, 0);
GD.loadSdFat(file);
GD.Clear();
GD.Begin(BITMAPS);
GD.Vertex2ii(0, 0);
GD.swap();
}
