I went through the ST External QSPI Loader how to and have verified my quadspi.c/h driver is good with the Winbond W25Q64 flash part we are using. However after I create the .stldr and load it into the STM32 Programmer it will not read from the flas...

I have encountered an issue on a project with the STM32H743 using FreeRTOS and TouchGFX v4.20.0. Occasionally the screen will freeze up and is not resposive to touch activity. I TouchGFX part seems to be frozen as we can view structure variables at...

I have been working on a project for many months now with TouchGFX v4.20. I was modifying some of the text strings I had defined in TouchGFX Designer and now the texts/TextKeysAndLanguages.hpp is no longer being generated.When trying to start the si...

We need to start building with the 1MB STM32H743ZGT while all the development has been done for the 2MB STM32H743ZIT. As far as I can tell I cannot change the micro in the .iot file for file generation even though the pin assignments and peripherals...

Any time I set any optimization level for GCC my application will not longer start. I can set G++ optimization to anything and it still works fine as long as GCC optimization is set to -O0. This project uses TouchGFX and FreeRTOS.While in debugger ...

Found a resolution for this issue...Apparently the enabling interrupts in the Init() function of the Loader_Src.c provided in the ST repository for the H7 external loader was hanging after it entered this function the first time. Made the modificati...

Since the programmer successfully reads the flash when it initially connects, what does the programmer do when the READ button is pressed that it would fail? I would think the loader is still in memory mapped mode since the HAL_QSPI_Abort() is only ...

the Loader_Src.c Init() is only called in the entry and resets and initializes the quadspi so I wouldn't think it would need QSPI Abort in there. The loader does call QSPI Abort before write, erase is done. Maybe I'm missing something in what you a...

I did have something wrong in my initialization...so now when I connect the programmer the loader will read the flash at 0x90000000 successfully! However when I press the READ button after that it fails again and when I try to program it fails on th...
