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.

Hi, sorry, doesn't looked to be fixed here, loads the code, jumps to the wrong place. GUI v2.2.0

Trying to do a full read of the device stops after the first complete RAM buffer fill of 0x7E000

​Hi Clive,

can you provide me command line you are using?

Best regards,

Houda

[Tesla DeLorean]

The command line input is shown approximately in the other thread, the path for the external loader was truncated for clarity.

The first test I had read 0x40000 bytes, after that looked to work I pushed it to 0x1000000. The file was 16MB in size, but only the first 0x7E000 bytes were valid.

I will note the equivalent command line on the old ST-LINK Utilities does successfully read the whole 16MB device.

Hi Clive ,

As answered in this thread    https://community.st.com/s/question/0D50X0000BTf3v0SQB/stm32-cube-programmer-v220-still-buggy​

i confirm there is issue to read big data .

The Cubeprogrammer development team is aware of this problem and will be corrected shortly.

Feel free to contact me for furthers details.

Regards,

houda

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
