eMMC programming fail in i.MX6

peterkctseng — Thu, 15 Oct 2015 01:23:36 GMT

Dear Sirs,

Sometimes, when we try to program the eMMC flash memory in our target board(i.MX6 + eMMC5.0), will get a programming fail message.

We used Freescale MFGTool to update eMMC, but also got the same error log.

This issue can not be solved so far. Could anybody help us to check what's the root cause?

The error message as below:

...

Hi Peter

errors like: mmc0: Got data interrupt 0x00100000 even though no data operation was in progress

were reported on other forums and seems as kernel sdhci driver bug as reported on

Cross Reference: /linux/stable/drivers/mmc/host/sdhci.c

In general one can try latest 3.14.28 kernel or post this on kernel mail list.

Best regards

igor
