STM32L552 (non-Q) current consumption dependency to VDD

I don't fully understand one thing with STM32L552 which has no SMPS: Does decreasing the VDD from 3.3V to say 1.8V reduce it's power consumption?All the measurements in datasheet and in AN5213 are done for operation ranges and in SMPS modes I see tha...

Resolved! STM32H7 QSPI kernel frequency too slow leads to read errors ?

I am developping a driver for a QSPI memory mapped memory on STM32H753.In SPI mode it works fine.When I switch to "quad io" mode (ie. 4 data signals) I read corrupted data. Adding some delays between reads improve the results (but doesn't completely ...
