I've bisected and can confirm this change is what breaks original
speed SD function on Milk-V Mars CM Lite (DFRobot mini router
carrier). Class 10 speed SD media does not seem to be affected.
Reverting the change allows the original speed SD media access to
function again. SD access is functional in Linux with and without the
change.
How to troubleshoot this?
Thanks,
