Could not see my customized external Flash Loader in ST Link Utility

[SBhuj.1]

I have developed External Flash Loader for STM32F756 & Cypress Chip.

I could compile my code in IAR. Also updated device info in file.

Then I copied that file in External Loader folder.

But I could see only a some blank spaces in some fields

please guide.

The StorageInfo structure/symbol is not being exported properly. You should review information in the .MAP file, and perhaps find an ELF dumping tool like FromELF or objcopy to dump the content/data within the file.

Attach the .stldr file if you want specific analysis of why it might not be working.

Hi Clive1,

Attaching the ".stldr" file. Can you please look into that ! ( Initial character(C) of file name stands for Cypress.

I will check in Cube Programmmer also.

Also I am going to play with timings of NOR flash as Current code is executing in RAM.

Thanks for Your Support

Hi Clive1,

Using Linker Map file & Project Settings of Example code, finally I could see my external Loader in ST Link Utility.

Further it is not getting programmed by giving some errors.

I have attached following images.

1) Programming Error Image

2) Map file Start photo & End Photo

3) One warning which is generated in my project

Please look into & guide

I might suggest you use the STM32 Cube Programmer with the diagnostic/logging level set to 3 so you can get the maximum amount of data.

The code will be hard to debug in-situ, it would be helpful to test the loader functions via an application framework.
