CubeMX v4.20.0 bug in clock configuration?

[Ismo Manninen]

When I generate code for STM32L151CBTx (FW v1.6.0) using CubeMX it enables MCI clock (RCC_ORCILLATORTYPE_MSI) in SystemClock_Config even if only HSI is enabled in the CubeMX clock configuration UI. Similar problem does not exist for other chip versions e.g. L152CBTx.

This misconfiguration causes HAL_RCC_OscConfig to fail.

Sorry for the inconvenience it may bring.

Hello

ismoman

I would like to thank you for your bug report.

I tested with CubeMX4.1 and this issue cannot be reproduced.

This version correct a clock configuratin regression that has passed through all our validation tests.

I recommend you to update your CubeMX to the 4.1 version.

Kind regards
