Why are there no folders for STM32H750B-DK? (I am noob.)

The MX25L6433F SPI Flash is used on the X-NUCLEO-GFX01M1 board. The use of the TouchGFX libraries makes it necessary the external loader for this flash.
The TouchGFX designer provides two application templates that support this flash, but only for the NUCLEO-G071RB board.
By downloading the application template through the TouchGFX Designer 4.15.0 you can get the External Loader MX25L6433F_STM32G071B_NUCLEO.stldr.

The X-NUCLEO-GFX01M1 board supports many other NUCLEO boards: there is a need to have many external loaders if you want to use TouchGFX libraries!

Based on this repository I have implemented the MX25L6433F_STM32F446RE_NUCLEO.stldr for X-NUCLEO-GFX01M1 and NUCLEO-F446RE.
I would like to share the project.
It's possible ?
If so, how should I proceed to do this?

hi everyone
The w25qxx IC is cheaper and more available than other flash ICs. Please add the driver for the w25q256FV IC.

I faced an issue while I worked through the erasing cycle on STM32H745I-DISCO with dual MT25QL512ABB8ESF-0SIT QSPI flash. When the QSPI is in dual flash mode, the CSP_QSPI_EraseSector() method will erase the next or the previous sector as well (based on the destination sector) i.e:

#define MEMORY_SECTOR_SIZE 0x10000

• If you erase sector 0 then sector 1 will be erased too ( CSP_QSPI_EraseSector(0 * MEMORY_SECTOR_SIZE, (0 + 1) * MEMORY_SECTOR_SIZE - 1) )
• If you erase sector 1 then sector 0 will be erased too! ( CSP_QSPI_EraseSector(1 * MEMORY_SECTOR_SIZE, (1 + 1) * MEMORY_SECTOR_SIZE - 1) )
• If you erase sector 2 then sector 3 will be erased too ( CSP_QSPI_EraseSector(2 * MEMORY_SECTOR_SIZE, (2 + 1) * MEMORY_SECTOR_SIZE - 1) )
• If you erase sector 3 then sector 2 will be erased too! ( CSP_QSPI_EraseSector(3 * MEMORY_SECTOR_SIZE, (3 + 1) * MEMORY_SECTOR_SIZE - 1) )

and so on.

I didn't find any workaround to fix this issue so right now for the demo code to work I had to erase the sectors first and then run writing loop:

	 for (var = 0; var < SECTORS_COUNT; var++)
	 {
		 if (CSP_QSPI_EraseSector(var * MEMORY_SECTOR_SIZE, (var + 1) * MEMORY_SECTOR_SIZE - 1) != HAL_OK)
		 {
			 while (1) {}
		 }
	 }

	 for (var = 0; var < SECTORS_COUNT; var++)
	 {
		 if (CSP_QSPI_WriteMemory(buffer_test, var * MEMORY_SECTOR_SIZE, MEMORY_SECTOR_SIZE) != HAL_OK)
		 {
			 while (1) {}
		 }
	 }

Hello,
i followed this guide several times, i correctly set my MT25L128, now i want to set MT25QL512, however i does not work properly.
When i program the flash memory through the Programmer, the number are shifted by one byte, like in this picture.
I copied and pasted the entire driver but it doen't work. The only different parameters are the CubeMX settings. I used:

1. prescaler = 2
2. FIFO = 1
3. No sample shifting
4. Flash size = 25
5. CS High Time = 2
6. Clock Mode = LOW
7. Flash ID = 1
8. Dual Flash = Disabled

Hi,

I have tried this project with STM32H7B3I-DK which use MX25LM51245G_STM32H7B3I-DISCO.stldr external loader with STM32CubeProgrammer. If I build this project and replace MX25LM51245G_STM32H7B3I-DISCO.stldr into C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\ExternalLoader it does not work? Did you test on this board please?

Please see bellow log into STM32CubeProgrammer

By advanced, thanks for your help,

I have compiled the "MX25LM51245G_STM32L562E-DK" project and generated a .stldr file. If I used generated file and tried to download the sample file using the STM32Cube programer it fails, If I tried with the default stm32 provided .stldr file then it works fine.

Is "MX25LM51245G_STM32L562E-DK" has been tested? Any configuration extra required, before building it?

Note: I am using the 9.10 version of the IAR workbench, during project open it shows "Project is in old formate, would you like to convert it for used this version?"

Hi, I am taking the source code from trying to read the ID from the External Flash, but I am having some problems, note very sure if there is maybe with the clock config.

The initialization of the OCTOSPI device seems correct:
int32_t result=0;
uint8_t *ID;
memset(&ID,0,sizeof(ID));
Flash.InterfaceMode = BSP_OSPI_NOR_OPI_MODE;
Flash.TransferRate = BSP_OSPI_NOR_DTR_TRANSFER;
/Initialaize OSPI/
if(BSP_OSPI_NOR_Init(0,&Flash) !=0)
{
return 0;
}
/Configure the OSPI in memory-mapped mode/
//result = BSP_OSPI_NOR_EnableMemoryMappedMode(0);
result = BSP_OSPI_NOR_ReadID(0, &ID);

When I reached the line "result = BSP_OSPI_NOR_ReadID(0, &ID);" the returned ID is 0x85c2c2 and it must be 0x3a85c2, seems like there is a problem in one byte.

any help?

Thanks,
Aitor

Could you provide linking scripts also for your IDE? It's very bad that you are njot supporting STM32CubeMX ide!
I'm trying all day to get it to work and I need to use cubemx but no luck as now!
The code wroks when programmed on the target flash memory but I cannot get it to be run from RAM.
