External Loader for STM32H533RE with W25Q32

[msalem88]

Hi,

I try build loaders for STM32H533RE using its nucleo board but it fails to read any thing using the cube programmer. i tried with nucleo H753 and it worked. i see that u already did loader for the H5 so would u please explain how or maybe update your tutorial to include the H5 instead leaving us here in the dark!

How to add spi flash loader

Hello @msalem88,

How to add your SPI flash into the STM32CubeProgrammer’s external loader Part 1 has been tested with NUCLEO-G070RB and External SPI memory (W25Q64).

In your example you used W25Q32. For that, I advise you to check the memory parameter settings in Dev_Inf.c file.

Thank you.

@KDJEM.1  i used W25Q32 with Nucleo H753 and it worked, I could read and write through cube programmer

Now I wanted to use it with Nucleo H533 but its not working. I have no idea why you want me to check memory parameters since it worked fine for H753. I changed the address in the linker to 0x20000004 as you mentioned in the tutorial.

Better share your linker for any H5 together with the other files. Check your repository for the external loaders. You have nothing for any H5!!!!!!

@Tesla DeLorean can u help here since i see you have experience in external loaders

This is what I use for mine, I'm using GNU/GCC w/MAKE, and not using CubeMX nor Interrupts, etc.

The H5's use a basis of 0x20003004, so not 0x24000004 of H7, or 0x20000004 of others.

If you give me your H53x pin designations I'll compile a W25Q32 build

STM32H533RETX.

SPI3_MISO -> PB0

SPI3_SCK -> PB1

SPI3_MOSI-> PC12

FLASH_CS -> PA0

Thanks

Pity that does use OCTOSPI in D0/D1 configuration. 

I'm probably not looking to code a SPI solution.
