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?

[ChahinezC]

Hello @Community member​,

Have you tried to reproduce the issue on ST board?

Chahinez.

[Freedom_Neo]

Hello @ChahinezC​ I tryed in STM32H7B3I-DK develepment board. It worked. But I use custom board. When I tryed in custom board, this problem occured. I reproduce custom board but this problem continues

[Osman SOYKURT]

Hello Freedom_Neo,

The code around BSP_OSPI_NOR_Init() looks good from my point of view, I don't know why you have that error raised line 52, you sure it's here ? I'll try to ask to my colleagues and keep you in touch.

/Osman

[Freedom_Neo]

Hello @Osman SOYKURT​ This fonction returned -5 value. RetVal = -5

int32_t RetVal = BSP_OSPI_NOR_Init(0, &Flash);

and BSP_ERROR_NONE value is 0. This function must return 0 value. So program goes Error_Handler()'s function 

[Tesla DeLorean]

Wouldn't you just debug/instrument your BSP_OSP_NOR_Init() implementation to understand where inside that it failed?

Work backward to the point that generated the error return.

[Freedom_Neo]

Hello @Community member​ BSP_OSP_NOR_Init()'s function returned -5 value. So This function must returned 0 value because

#define BSP_ERROR_NONE 0

This problem occurs below in stm32h7b3i_discovery_ospi.c source file

Hi,

i already replay this in last post.

First edit My flash pin mapping in stm32h735g_discovery_ospi.h with your pin-map

Then set to single SPI so:

 ospi_nor_int.InterfaceMode = BSP_OSPI_NOR_SPI_MODE;

 ospi_nor_int.TransferRate = BSP_OSPI_NOR_STR_TRANSFER;

[Freedom_Neo]

I added.

[Freedom_Neo]

Hello @Patrickhiapello​ The error is gone. Thank you for support.

Where we set below code?

Then set to single SPI so:

 ospi_nor_int.InterfaceMode = BSP_OSPI_NOR_SPI_MODE;

 ospi_nor_int.TransferRate = BSP_OSPI_NOR_STR_TRANSFER;

[Freedom_Neo]

Hi Everyone,

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

[Osman SOYKURT]

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.

/Osman

[Freedom_Neo]

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

 

[Peter Chang]

If BSP_OSPI_NOR_Init() function fail then you can not do anything.

We need detail to known which point failed.

I think this Flash is damaged. Please replace it.

And, Make sure the Flash was come from authorized channel.

[Freedom_Neo]

Hello @molecule.192g​ I replaced with new FLASH. But this problem continues. FLASH came from Macronicx sample

[Peter Chang]

Dear Freedom, So, finally you solve external loader problem by set Flash interface to SPI-STR mode. It means OPI-DTR work in your project, but it can not work in external loader. Am I right ? If yes then it's a very strange things. I can help to detail trace this issue if you want. Thanks & best regards ! Peter Chang 張耀�? Macronix International Co., LTD.

Dear @Community member​ 

Do you have ant opinion this problem?

[Tesla DeLorean]

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.

[PChia.2237]

Hi @Community member​ 

at which point you are?

I mean, your code is working with BSP_OSPI_NOR_Init() ?

When you have this working you have to do the external loader.

You post " These files for board not for STM32H7B3IIT6."

Okay.

You have to see the more simular to your application, take the example code and modify for your application to have extenal loader

okay?

[Freedom_Neo]

Hi @Patrickhiapello​ Thank you for support. I am working on external loader for my board. The reason for this problem my board pins different of STM32H7B3-DK has pins.
