[STM32F103 + FreeRTOS + uGFX + BMP = HardFault]

Hello,

I have some troubles with displaying BMP monochrome picture on display. I use the ugfx library with the 128*64 display (ssd1306 controller) and  STM32F103CBT6; FreeRTOS uses HEAP4 memory manager. uGFX starts working in a dedicated task (uGFX init) and  LOGOis displayed. In process task I try to drawing image (BMP 24*24 pixels).

void displayPainter::vPrintScreen(uint32_t numScreen, screenPayload_t& data)
{
		switch (numScreen)
		{
		case 0:
		{
			static gdispImage myImage;
			gdispImageOpenFile(&myImage, "gasoline.bmp");
			gdispImageDraw(&myImage, 0, 0,  myImage.width, myImage.height, 0, 0);
			gdispImageClose(&myImage);
		}
		break;
		case 1:// Gazoline for station in km

		break;
		case 2:// Error menu enter

		break;
		case 3://Error entity

		break;
		case 4://Eraze error

		break;
		case 5://No eraze error

		break;
		default:
		//Startup LOGO and TEST
		break;
		};


}

But code breaks into the HardFault Handler in gdispImageOpenFile() function (in allocating memory procedure for priv->palette value). This error occures with images, strings and LOGO are drawn correctly.

I tryed to insert Image drawing code to uGFX initialization task. Same error  occured.

What's the matter? What am I doing wrong? Thanks in advance/
