For touchGFX application, I have created a project for implementing touchGFX(STM32F411RE) with external SPI flash memory(W25Q32) but I am facing a problem in programming the chip with an external loader but the external loader working well in using a

Hello MMadh.1,

Strangely enough, you mention using STM32F411RE but the ST-link says your board is NUCLEO-F091RC.

Are you using CubeProgrammer or CubeIDE to download your file ? I recommend you try reading your Flash, erasing sectors and downloading some .hex or .elf file directly using CubeProgrammer.

Likely using the NUCLEO in lieu of a stand-alone ST-LINK/V2 pod, cheaper/available..

The 0x431 Device ID is consistent with it talking too an STM32F411RE.

Debugging External Loaders can be a challenge, but all the pins/peripheral can be used, for example diagnostic/progress information via USART

[User16438042334827474767]

@Alexandre RENOUX​ NUCLEO-F091RC onboard STlink was used for programming the STM32F411RE MCU and the problem was found in the external loader Loader_Src.c file.I am just added HAL_ResumeTick() and HAL_SuspendTick() functions in every operations.working project file is attached.

I ran into this issue a while back and IIRC it is a known issue with internal flash interacting with the stm32programmer library.

The fix is to add "monitor flash mass_erase" to initialization commands in debug configurations > startup
