Hello i created a custom external loader following this guide. My check code in the main (see the video) works. I can read in memory mapped mode, i can write and i can erase sectors and full chip.

I can write to it simple bin files using stM32 Programmer, but, when i try to upload a touchGFX application (created following this video) the programmer say error "Error: failed to download Segment[1]". The full log is

Ok, i changed the FLASH memory to a much supported by examples like MT25QL128ABA1EW9. I added a pullup resistor to CS pin, and i added a decoupler capacitor to VCC and now it works! So i don't know the problem, but now works and i'm happy!

Turn the log verbose level to 3

External loader can output it's own diagnostic/telemetry via a UART

Entry in to Init() the second time doesn't complete, make sure it is not stuck in a loop waiting for completion, or expectation that HAL tick will advance via an interrupt (SysTick or otherwise)

To have some chance of knowing what's happening internally you'll need to instrument the code

This is my Init() function copied from the video i cited before

int Init(void) {
 
	*(uint32_t*)0xE000EDF0=0xA05F0000; //enable interrupts in debug
 
	SystemInit();
 
/* ADAPTATION TO THE DEVICE
 *
 * change VTOR setting for H7 device
 * SCB->VTOR = 0x24000000 | 0x200;
 *
 * change VTOR setting for other devices
 * SCB->VTOR = 0x20000000 | 0x200;
 *
 * */
 
	SCB->VTOR = 0x20000000 | 0x200;
 
	HAL_Init();
 
    SystemClock_Config();
 
    MX_GPIO_Init();
	
	__HAL_RCC_QSPI_FORCE_RESET();  //completely reset peripheral
    __HAL_RCC_QSPI_RELEASE_RESET();
 
	if (CSP_QUADSPI_Init() != HAL_OK)
	{
		HAL_SuspendTick();
		return LOADER_FAIL;
	}
 
	if (CSP_QSPI_EnableMemoryMappedMode() != HAL_OK)
	{
		HAL_SuspendTick();
		return LOADER_FAIL;
	}
 
		HAL_SuspendTick();
		return LOADER_OK;
}

all of the functions inside it work.

I will assume that you ran different tests in standalone before you do the integration into your application.

Things to try without any internal flash programming - just run tests on the external loader:

Disable interrupts - For that you would need to remove HAL_Delay()

Make sure you don't have the watchdog enabled

Program the external memory without erasing it - assuming the memory is already erased.

Erase different sectors - check if the issue is related to a specific sector

By the way what memory are you using?

Let us know about your findings.

Ok, i changed the FLASH memory to a much supported by examples like MT25QL128ABA1EW9. I added a pullup resistor to CS pin, and i added a decoupler capacitor to VCC and now it works! So i don't know the problem, but now works and i'm happy!
