How External OCTO SPI Flash activete for custom board design?

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?

I added.

Hi Everyone,

I've made progress. But I am getting an error while uploading. What do you think could be the reason?

Hello Freedom_Neo,

We have a software called STM32CubeProgrammer that can help you erasing your memory. You can try to install it and then follow this steps :

1- Connect your board to your PC and click on "Connect" button (top right)

 

2- Click on the 2nd button on the left panel (with the arrow) and click on "Erase flash memory" and "Full chip erase".

 

3) If you want to erase your external memory, you can do the same with "Erase external memory"

You can also try to remove your breakpoints as it says there is a error with them.

Check Erase at the BSP level,​ perhaps look at earlier failure, and if expectations of different non-volatile settings in memory device.

Hi @Osman SOYKURT​ 

I did 1. and 2. steps. But The failure accurs 3. step. The deletion process takes 4-5 minutes, but at the end it gives an error as follows.

You can also try to remove your breakpoints as it says there is a error with them.

Dont have any breakpoint anywhere

Hi Freedom,

good jobs. This is second steps. You need to tell to stlnk how to program your external flash.

If you have use same micro and same flash in the same pinmap of ST boards you can select one of *.stldr file of External Loader.

Otherwise (like in my case) you have to create this file.

Good luck 🙂

Failing same way as your code, initializing chip prior to erase. Try to understand why read-back or commands fail in your implementation.

Check chip defaults written into non-volatile related to widths and pin usage. Read datasheet for part in relationship to the commands, and reporting, that is failing.

Set Verbose level to 3 for additional details/information from the tool.

Hi @Patrickhiapello​ 

My MCU: STM32H7B3IIT6 -> Board:STM32H7B3LIH6QU

My FLASH: MX25LM51245GMI00 -> Boad: MX25LM51245GXDI00

So I use below of *.stldr file of External Loader.

MX25LM51245G_STM32H7B3I-DISCO-SFIx, 0x90000000, NOR_FLASH, MX25LM51245G_STM32H7B3I-DISCO-SFIx.stldr

Does I have create must this file?

[Tesla DeLorean]

You need a loader that works with your board and chip level choices. Close might not be close enough.

Perhaps need to carefully review differences for GMI vs GXDI at data-sheet level.

Especially configurations, defaults, and non-volatile / delivered settings.

[PChia.2237]

You can try, but you need to see also pin mapping betwwen flash and micro yours and ST boards. If there are different connections you have to create this file
