Hi,

It has HardFault error in Cortex M3 when drawing JPEG file with emWin.
I used Bin2C to convert JPEG file to C file.

Code:

void jpegTest(void)

{
GUI_JPEG_INFO Info;

GUI_JPEG_GetInfo((unsigned char *)actestJpeg, sizeof(actestJpeg), &Info);
GUI_GotoXY(0, 0);
GUI_DispDec(Info.XSize, 3);
GUI_GotoXY(0, 20);
GUI_DispDec(Info.YSize, 3);
GUI_Clear();
GUI_JPEG_Draw(actestJpeg, sizeof(actestJpeg), 0, 0);
}

The resolution of JPEG file is 176x220 and it can display 176 & 220 on screen.
The MCU hangs up in HardFault_Handler when calling GUI_JPEG_Draw().
I defined 64KB RAM for GUI, it should enough for 176x220 JPEG image.

//
// Define the available number of bytes available for the GUI
//
#define GUI_NUMBYTES 0x10000
//
// Define the average block size
//
#define GUI_BLOCKSIZE 0x80

Hi,

I solved the problem by increasing the stack size.
