eMMC write error in IMX6 Sabre AI board

eMMC write error in IMX6 Sabre AI board

[vadivelan mani]

Dear all,
     I'm facing this unique problem during emmc write operation. I'm using a
Toshiba emmc device on Sabre AI board and linux kernel version 3.0.35.

The write operation is successful when i disable multi-block read/write.
But when multi block read/write is enabled, the writes fail for data of size
above 12KBytes. Please find the logs below for your reference. Any data
write upto 12KB, there is no problem. The error message is a data crc error
which i'm unable to figure why it is occuring.

Please try 3.18-rc3.

Hi,
 Thanks for your suggestion. But my kernel is fixed to version 3.0.35 and hence unable to use a different kernel. Please tell what is the problem in this kernel version if you already know. That would be very helpful.

NOTE: There may be some copyright messages below my mail which gets added automatically. Kindly ignore those messages.

Thanks and regards,
Vadivelan.

If you use such an old kernel, you are basically on your own;
community development & support takes place on top-of-tree.

Note that 3.0.35 is 227048 patches behind 3.18-rc6, and this does not
even take into account that you are probably using 3.0.35 plus thousands
of vendor patches. You can't seriously expect anyone in the community to
help you with issues which have long been solved.

Robert

I understand. Ok then let me try to solve the issue by myself.

Thanks,

Out of interest, why can't you go with mainline?
