MFG tool Programming Stop for eMMC v4.5 for i.MX6Q

Dear all,


We made an original board using i.MX6Q.
In our system, Android4.4.3 boots from eMMC device.
We used MTFC8GLDDQ-4M(version4.4.1) made in Micron until now.
But, MTFC8GLDDQ-4M becomes EOL.


For that reason, we replaced it with MTFC8GACAANA-4M(version4.5.1).
And we tried to program an OS image into MTFC8GACAANA-4M by using MFG tool.
However, When mkfs is performed, MFG tool stops.


The following log is output about partition.

    mmcblk3: mmc3:0001 P1XXXX 7.20 GiB
    mmcblk3boot0: mmc3:0001 P1XXXX partition 1 16.0 MiB
    mmcblk3boot1: mmc3:0001 P1XXXX partition 2 16.0 MiB
    mmcblk3rpmb: mmc3:0001 P1XXXX partition 3 128 KiB


- In MTFC8GLDDQ-4M, we  were able to program it by MFG tool without a problem.

- In MTFC8GLDDQ-4M, the indication of Partition is MMC08G. 

- OS image is the same.


Please refer to attached log files.


We thought that version of eMMC was a cause.
And we apply the method of the following URL.
  card->ext_csd.rev> 6

EMMC 5.0 and EMMC 5.1 work on i.MX6


However, the problem was not improved.

Probably we suspect that this problem is caused by setting of MFG tool.


Would you tell me the point that we must modify about MFG tool?


May I have any advice?
