Writing rootfs.ubifs image to NAND flash using MFG-Tool

isaacnickaein — Wed, 09 Sep 2015 09:31:51 GMT

I've been using U-boot nand write.trimffs command to flash rootfs.ubifs image to the NAND flash of i.MX6DL.

We have decided to switch to MfgTool for production. The problem is that when there are some bad blocks on NAND of i.MX6, MfgTool has issues during write and the final written image is corrupted. The same i.MX6 module can be programmed correctly by u-boot.

Here is the profile I am using:

Here is the module output on serial debug during flashing by MfgTool (Note mtdblock: erase of region [0x4a0000, 0x20000] on "linux" failed error and its following errors):
