I have included the following line in /boot/config.txt to overclock the SD card:
dtoverlay = sdhost, overclock_50 = 100
When I save the changes in the config.txt and restart the Raspberry 3B + I get the following message:
waiting for root filesystem
Then I have to modify the config.txt again from the PC by removing the dtoverlay line and putting the mini sd back on the Raspbeery 3B + OSMC starts without problems.
I had this same configuration in the DietPi distribution with Kodi and I never had errors of this type. In fact, overclocking the SD in DietPi, I did notice that the menu was more fluid and the skin took less time to boot.
Is it possible that the syntax I am entering in the OSMC config.txt to perform the overclock is not correct?
I have the latest OSMC version based on Kodi 18.2
