Bug with latest version and STM32G0B1KB MCU

[RHelv.1]

When attempting to program an STM32G0B1KB MCU (128kB of flash) with the latest version of STM32CubeProgrammer (2.13.0) the target information flash size says it only has 63kB of flash. This is not a valid flash size for this family of MCUs, and it does not allow the MCU to program if the flash size is greater than 63kB but less than the maximum 128kB.

 

When I revert to STM32CubeProgrammer v2.11.0 this is no longer an issue and the proper flash size is shown. All other variables (hardware, programmer) are the same.

 

This is a major problem and delayed our manufacturing by ~2 days as we thought we had more serious hardware problems.

This problem does NOT exist for the STM32G0B1KE variant (512 kB).

Thanks,

Rob
