Is this addressing the clock drift (the calibration done?) ? I can see it done now with this patch.

[bcostm]

No this is not related to HSI calibration. The CRS (Clock Recovery System) is for the HSI48 clock used by USB.

LGTM

One nit:

//HAL_RCC_MCOConfig(RCC_MCO1, RCC_MCO1SOURCE_HSE, RCC_MCODIV_2); // 4 MHz

this is deadcode and should be removed? If needed, it can be found in the drivers/app notes , somewhere, not here.

OK. I have removed the dead code in the last commit.
