Extrenal Loader error: failed to erase memory for STM32H50B DK Board

[NKuma.20]

There is this error which I have encountered while accessing the QSPI external flash laoder.

I had followed the below link for building up the .stldr file:

https://github.com/STMicroelectronics/stm32-external-loader/tree/contrib/Demo_Project

Now when I'm using STM32CubeProgrammer to upload a .bin file, I'm getting the following message:

What could be the reason for this ? If anybody could help me on this.

Attaching the .ioc file for reference.

Hello @NKuma.20 ,

Could you please check the memory flash size, page size, dummy cycle...

Are you able to upload a .bin file using the available external loader in STM32CubeProgrammer without issue?

I hope this help you.

Thank you.

Yes, I'm able to upload .bin file using the external loader available in Cube Programmer.

But the custom file which I created is giving us this issue.

Hello @NKuma.20 ,

Glad to know that you are able to upload .bin file using the external loader available in STM32CubeProgrammer.

I noted in the .ioc file that the flash size "23" is wrong and should be "27". Please check the dummy and page size.

I recommend you when create your customer loader to start with an available example like as MT25TL01G_STM32H743I-EVAL and to follow the steps shared in How to implement and use your own external flash l... - STMicroelectronics Community FAQ.

Could you please share the project for checking?   

Thank you.
