FP-AI-VISION - SDCARD format or not working?

I have the latest FP-AI-VISION-1, the 747i-DISCO and the BCAM board. I can see the image, but cannot storen anything to a SDCARD. I tried an SDCard that is readable in the original 747i-DISCO demo code, so at least the interface and card seem to work...

Resolved! STM32L011E4 ADC input impedance

Hi,the STM32L011E4 has a R_ADC of 1kOhm max according to the datasheet. Does this hold true for standard channels as well, or do standard channels have a higher impedance? The table with R_AIN_max isn't super helpful in this regard as my calculation ...
