        That problem is caused by SPI frequency.
        Try to lower the SPI frequency from TFT driver then it should work just fine.
        In most cases, 27Mhz SPI work just fine with most TFT's.

            I tried all the tft spi sd frequencies and I still have the problem!
            an idea?

              @richard The TFT SPI frequency is defined on In_eSPI_Setup.h file from M5Stack library at line 202: https://github.com/m5stack/M5Stack/blob/1772fd68743a7728e64ab6d24b931e1183599981/src/utility/In_eSPI_Setup.h#L202
              Try to set it to 27000000

              The SD SPI freqency can be different than TFT SPI frequency, since SD is on a different SPI bus.

                    my code

                    #include <M5Stack.h>

                    void setup(void) {

                    M5.begin();

                    M5.Lcd.setBrightness(200);
                    M5.Lcd.drawJpgFile(SD, "/corto.jpg"); // Load background from SD

                    //M5.Lcd.drawJpgFile(SD, "/corto_1.jpg", 0, 20, 300, 200);
                    // M5.Lcd.drawJpgFile(fs::FS &fs, const char *path, uint16_t x, uint16_t y, uint16_t maxWidth, uint16_t maxHeight, uint16_t offX, uint16_t offY, jpeg_div_t scale);
                    }

                    void loop() {

                    M5.update();
                    M5.Lcd.drawJpgFile(SD, "/corto.jpg");
                    delay(1000);

                            Here is the test using your code (with small modifications and relevant comments)
                            and standard m5Stack library from PlatformIO:
                            0_1529610830592_corso test.jpg

                            And here is the result:

                                      @richard No. i didn't tested with arduino "ide". I uninstalled that from my PC because is mostly useless...

                                      I use Visual Studio, Eclipse or PlatformIO.

                                      I uploaded the PlatformIO project for your code to github: https://github.com/botofancalin/M5StackJpgtest
                                      The M5Stack library is already installed local into project.
                                      All you have to do is to download the repository and compile the code.

                                        Maybe a stupid question (or two) but I'm going to ask anyway.
                                        Is there a hardware limitation for this i.e. is there a card size limit and a formatting requirement?
                                        Is there a specific image limitation for the image?

                                          I use Visual Studio too.
                                          i have just tested your programm and i still have the problem.
                                          I think it's a hardware problem.

                                            I think there is no limitation on card size.
                                            There might be a limitation on card read/write speed and that depend on the sdcard manufacturer and model.
                                            As i know, the cards formatted as FAT32 are preffered.

                                            That problem can be caused by the ILI9341 controller from the TFT.
                                            If that is the case, the only solution is a replacement.
