Will it be a problem to calibrate two ADC instances simultaneously on two different cores?
The reference manual S32K3XXRM notes that:
ADC must be calibrated before it can do meaningful conversions. The application must prevent any start of conversion before
the ongoing calibration has finished successfully. No conversion trigger may be received during calibration.
The calibration is implemented by, among others, powering-down the ADC instance.
Therefore, it seems to me that one ADC instance can not do a start of conversion before the ongoing celebration has finished, but another instance can start a calibration at the same time.
Is my line of thinking correct?

Hi, I don't think it is a good idea, because in such case voltage references could be sampled by two ADCs at once, what's not recommended and should affected conversion accuracy.
I would recommend to perform ADC calibrations sequentially.
