Hi Eric,

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.
One colleague of mine tested eMMC erasure on a mx6qsabresd revC5 board with a eMMC from Micron and it worked fine.
So far I see:
revB and revC5: works revC2 and revC4: don't work
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=c5054d66bdcda029f0485958c87bd5154ccee591;hb=HEAD#l390Seems 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.
This piece of code came from: 7a5b80297bc6cef ("mmc: fsl_esdhc: Poll until card is not busy anymore")
Yes, ENGcm03648 is not listed in mx6 errata document.
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.
May I see your change, please?
Thanks,
Fabio Estevam
