Re: How to prevent high speed mode due to signal integrity problem

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,
   We have a board here where there is a signal integrity problem on the MMC
bus.  It works fine at 25MHz, but does not work in higher speed modes.

Is there an easy way to disable all the high speed modes?  Perhaps from the
device tree?

I tried searching the archives, but gmane seems to be not working.

I'm using a stock 4.8.11 kernel.
Host processor is i.MX6

Thanks,
  -Caleb
