Hi,

I am using STM32L4x6 MCU. I am trying to reduce the overall power consumption. For that I am running MCU @ 2MHz in LP Run mode.

Currently the SDMMC1 transfer clock is set to 800KHz. But I want to increase while keeping MCU in LP Run mode. When I am trying to increase it to even 1MHz, the SD card stops working. So is it possible to increase the clock for SDMMC1?

Thanks,
Dhaval
