Continued frustrating time with STM32 Cube Programmer

[Tesla DeLorean]

Trying both 2.7 and 2.8 downloading 128MB (and smaller amounts), completes after one read interaction, about 0x7D400 bytes

Hello @Community member​ ,

Thanks for your feedback.

I escalated this issue to involved people to take a closer look at the problem.

Hi @Community member​ ,

Could you please provide files used such as h747ext128m.bin?

It is a file that STM32 Cube Programmer will generate as it's is being ask to pull the content currently on the QSPI IC back into the PC.

Where if successful you'll end up with a 128 MB (or 64 MB if low amount specified)

Current behaviour is that it bombs out after a single read, the read size being determined by the amount of slack SRAM memory after the loader is accommodated.

This is using an ST board, with an ST (.stldr) External Loader

Hi @Community member​ ,

Issue confirmed and our team are working to fix this.

(Internal ticket 111180: This is an internal tracking number and is not accessible or usable by customers)

Thanks

Thanks.

As I've offered before​, I can help the team with beta and QA testing this stuff, as I have a background in ELF and object loaders, and mass storage devices. I also have a lot of STM32 systems fixtured to take an assortment of QSPI flash chips.

The main external loader repository is here https://github.com/cturvey/stm32extldr

Supporting a lot of chip and pin combinations, both those encountered, and built to order as needed.
