Could it be a silicon revision issue? My CPU is i.MX6Q rev1.2.
I will try to test this on other sabresd boards next week.
I tested this on other mx6qsabresd board I have and I could see the error.
The board that failed is revC2
Boards revC2 and revC4 failed. (Both are TO1.2)
Board revB (with TO1.1) works fine.
I've also recently seen this on two different custom boards. Both are running i.MX6Q TO1.2 and both are using eMMC from Micron.
The code which is generating the error message:
http://git.denx.de/?p=u-boot.git;a=blob;f=drivers/mmc/fsl_esdhc.c;h=c5054d66...
Seems to refer to an errata for the i.MX35 (ENGcm03648): http://cache.freescale.com/files/dsp/doc/errata/IMX35CE.pdf
I don't see any reference to the errata in the i.MX6 docs.
Ignoring the error (removing the return statement) seems to leave things in a workable state, so I suspect the problem isn't with an insufficient timeout.

Eric
