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,

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.

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
