stm32-mw-openbl missing functionality (GetChecksum, maybe more)

[a34fheuak]

The stm32-mw-openbl project supposedly implements the system memory bootloader available in all STM32 MCUs.

However, there are some missing functions:

• The GetChecksum command is missing, but it is documentend for example in AN4221 (I2C interface for the system memory bootloader)
  • See also my issue here: Where is Get Memory Checksum command (i2c interface) · Issue #5 · STMicroelectronics/stm32-mw-openbl · GitHub

I am posting here because it seems that nobody reads/replies to issues on the github project.

Can you update the github library accordingly, so that it provides the full feature set?

I think it says it implements equivalent functionality, not that it's actually used, for the system loaders themselves.

It's run out of Europe, so perhaps expect little response during August.

H​ard to gauge interest in the project.

Hi @a34fheuak​,

Sorry for the very late response.

This command is not yet implemented in Open Bootloader MW and its implementation is planned for upcoming releases.

This command is not widely used and not implemented in all products, so its implementation was not a priority.

Best regards,

Aymen.
