Failed to list external Loader

Weird

Perhaps something specific about the form/structure of the ELF object.

Or a very long path/file name combo

Does STM32 Cube Programmer work in stand-alone mode?

STM32CubeProgrammer works in stand-alone mode.

The versions are:

• IDE: STM32CubeProgrammer v2.9.0-RC01
• Stand Alone: STM32CubeProgrammer v2.9.0

Hi,

I have the same issue with same versions of Cube Ide and Cube Programmer.

I just tried with latest STM32CubeIde version 1.9.0. The plugin STM32CubeProgrammer is update to v2.10.0.

Same problem!!

The error should not be in CubeProg. Must be in CubeIDE code.

The IDE tries to populate a list of loaders showing more than the file name, like: memory start address, length, ...

In order to do so the IDE tries to read the elf-file... If the loader (stldr-file) is built with some specifical way possibly stripping som headers I guess that the tool could generate such error.

We should not "fail the scan", we should simply not populate all fields... Just my first guess.

Could you share the elf-file and preferably also the project and code so that we can see how it is built?

You find my e-mail in my profile.

I have exactly the same problem, but on Linux.

I copied MX25L6433F_GFX01M2_STM32G0.stldr to the directory where other ExternalLoaders are. If I click "Scan" I get the same error message, "Failed to list external loaders".

If I delete the file from that directly, scan works.

I can also just keep MX25L6433F_GFX01M2_STM32G0.stldr in original directory, and copypaste path to that file to the "External Loader" field in Debugger settings. IDE will accept that, and will pass the filename to gdbserver while flashing. However the flashing does not work, it always fails with "Load failed".

I'm slightly ****** about this. I bought a STMG071RB Nucleo board and GFX01M2 module, genuine ST modules. Then downloaded STM32CubeIDE and X-CUBE-DISPLAY. I'm able to build the example project with no errors, but can't program the board because this External Loader issue.

I have not yet written a single line of my own code, everything is straight from ST and not working.

Other projects (without extloaders) build and program fine.

Update to my last message: Just downloaded STM32CubeProgrammer, can confirm that the same ExternalLoader works right away and I finally was able to program my board. :)

btw @mattias norlander​ , STM32CubeIDE External Loader list does not have any details you mention (memory start address, length).. Just file names in a huge dropdown menu which can't be searched. STM32CubeProgrammer has much nicer GUI here.

I had some internal discussion and this problem had already been internally reported as a bug.

(ST Internal ticket reference 119761)

I will see if we can provide a fixed stldr-file in this thread before next X-CUBE-DISPLAY release.

@TSuik.2​, help me prioritize the work for the responsible team... Is it only this stldr-file which you currently need? MX25L6433F_GFX01M2_STM32G0.stldr.

Let us know which files are the most important for quick fix and I hope we can prioritize...

@TSuil2 I have the NUCLEO-STM32G071RB + X-NUCLEO-GFX01M1 after fighting the issue I found:

D:\STM32Cube\Repository\Packs\STMicroelectronics\X-CUBE-DISPLAY\2.0.1\Projects\NUCLEO-G071RB\Applications\GFX01M1_HelloWorld\Binary\GFX01M1_HelloWorld.bat

I had to edit the paths to where I installed STM32CubeProgrammer and then I got the extfirmware loaded. Read up on the process to generate external firmware loader, informative. FYI: TouchGFX (4.18.1) generates external loaders, they fail, but that is another thread.
