STM32 Cube Programmer v2.1.0 not working with STM32H750B-DK QSPI External Loader

[Tesla DeLorean]

Stock hardware, and also updated with v35 ST-LINK/V3 firmware

Using MT25TL01G loader for either H750B-DISCO or H745I-DISCO External Loaders

Tried on two different machines

QSPI viable using my own apps, and stock demo.

Not sure the tool actually calls Init function, seen other issues where first read returns zeros, this case times out every time, never seen it read the memory.

The Command Line version also has a heap of issues.

If the External Loader exports a "Read" function, the tool doesn't bother to load the loader before executing the "Init" function.

If one of the *.stldr in the ExternalLoader (QSPI NOR) lacks an "SectorErase" function the GUI tool never starts properly, you get the splash screen, but app never loads.

@STOne-32​ @Khouloud GARSI​ 

Can someone from the STM32 Cube Programmer group please work with me to fix the tool so it works properly? The tool behaves differently with H7 targets and doesn't relocate some of the entry points properly from the .ELF/.STLDR side.

The ST-LINK Utilities (v4.5.0 GUI, v3.50 CLI) work better in this regard, the CLI seems to allow for >1MB interactions with a file.

[Tesla DeLorean]

Another custom having more luck with Cube Programmer, and less with ST-LINK Utilities, but this build wasn't working in Cube Programmer for me either.

I'm doing work with a number of FLASH parts and loaders

​Hello Clive,

Thanks for your feedback.

This problem is already fixed in last CubeProgrammer version V2.2.0 published on ST WEB .

Can you please test an tell me if it is Ok?

Do not hesiate to contact me for furthers details.

regads,

Houda

[Tesla DeLorean]

Thank you, I will check this shortly.​

[Tesla DeLorean]

This continues to be a problem.

The first time it loads the .ELF it gets the Init address wrong, the second time (after disconnect/connect) it loads correctly.

This seems specific to the H7 where the STLDR are put in the 0x24000000 RAM rather than 0x20000000
