Touchgfx and external flash with quadspi

[SGasp.1]

Hi guys... I am trying to udpate an external flash during the booting process. We already developed an external loader which is working fine when we use it with stm32cube programmer. I developed a code for loading a file from a usb key and calling a routine which is already present in the external loader for writing the external flash. The poin is that I am able to write in the external flash but the pictures a bit wrong. You can see them in the attachments... Whst colud be wrong ? you can also find the .hex file that I am parsing.. Any idea or help ? thanks a lot ..

I The external flash memory map is shown in the attachments... I discovered that I am able to write correctly only the first 16 Sectors... then I start to see differences in the memory that I expect...

	current_addr = 0;

	while (current_addr <= address) {
		current_addr += MEMORY_PAGE_SIZE;
	}
	current_size = current_addr - address;
 
	if (current_size > buffer_size) {
