How External OCTO SPI Flash activete for custom board design?

[Freedom_Neo]

I am using below development tools

MCU: STM32H7B3IIT6

IDE: STM32CubeIDE Version: 1.8.0

GUI: TouchGFX Version: 4.18.1

SDRAM: IS45S16800F-7CTLA1-TR

FLASH: MX25LM51245GMI00

Schematic

I am trying to activate octospi as custom board design, but the program gives an error. The program gets an error at the following place? What do you think could be the reason?

Hi @Patrickhiapello​  I created external loader. But external loader file dont seem debug window. Do you have advice?

Great!

Good job!

ahahah yes i know 🙂

If you put this file for STM32CubeProgrammer you can "see" the file.

But if you put the same file for STM32CubeIDE you can not "see" the file.

Correct?

The problem is the name inside Dev_Inf.c

"QSPI_flashloader_CSP",      // Device Name + version number

Has to be egual to generate file stldr so ->QSPI_flashloader_CSP.stldr

Put name you want egual inside and outside the file in Dev_Inf.c

"franco",      // Device Name + version number

and generate file franco.stldr

Then you finally have your extenal loader work in STM32CubeIDE!

Hi @Patrickhiapello​ Thank you for support. I did your advice and I could see .*stldr file. But I see failed to erase memory. I wil create new post with "External OctoSPI loader how to".

Topics can be mixed. I will create a new topic.

Well that's me, and I'm monitoring things, but a week in and I'm not sure which pins you're using, and I don't have this IC or a STM32H7B3-DK board.

https://github.com/cturvey/stm32extldr/blob/main/h7a3_octo_pins.txt

Can we PLEASE establish which pins you're using?

At least with those it might be possible to patch/fix the DK's .stldr to match your hardware configuration, and see if it is simply that causing the issues, or if it's some mode/setting disagreement.

Dear @Community member​ Thank you for support. I am using below pins.

// OCTOSPIM P1
// D0   PD11:AF9

Ok, so significantly different from DK and EVAL boards
