Using Mega2560 - HX8357B 480x320
I've tried using Imageconverter565. But when I try to load it in Arduino it just displays some jagged lines (it's like the image is stretched and copied). I've also tried using the images that comes with the SdRaw library. The only thing that would load is the "wait4gps.raw" (edit: SK400500.raw also loads)
int ret = myFiles.load(0, 0, 480, 320, "wait4gps.raw", 1, 1);
Tried it without the 1 at the end.
Tried 320, 320.
Tried different sizes of the same image.
Tried SPI_HALF_SPEED
Serial for wait4gps.raw

Serial for boost.raw (timer just gets longer with a bigger image)

Here's the code

const uint8_t chipSelect = 53;
// file system
SdFat sd;
void screenHome() // draw main home screen showing overview info
{
myGLCD.clrScr(); // clear the screen
myGLCD.setColor(255, 255, 255);
myGLCD.drawLine(0, 0, 100, 200); // draw line above dock
int mytime = millis();
int ret = myFiles.load(0, 0, 480, 320, "wait4gps.raw", 5, 1);
Serial.println(millis() - mytime);
Serial.println(ret);
}
void setup()
{

}

// see if the card is present and can be initialized:

Serial.println(F("Card failed, or not present"));
