Oggetto: Imx53 sd card read write timing
Dear all,
I've finished today to port our changes from the old FSL kernel we used
(2011 version, v11.05) for our board based on imx53qsb.
Everything is working fine now, using the FSL kernel from Master branch,
except one thing.
Compared to the previous (very old) version of the kernel, we noted that the
uSD card read/write timings are a lot more slower than before (also the
system kernel loading, seems two times than before)
Now i really don't know where to point my finger first.
Maybe something inserted in the sdhc driver? Or the journaled filesystem?
Really i don't know.
Does someone have faced a similar problem in the past?
Thank you so much
My best regards
Simone
