[yocto] <EXT> Re: wic utility

[Srinivasan, Raja]

Sorry for the delay.

 

Yes. Simple things worked fine. I wanted to copy  a dir to a partition inside the sdcard image and that was not successful.

 

I ended up writing a utility to perform the function I needed. It is somewhat customized to our image but if anyone needs, I will be happy to share my findings. srini

It seems that it works fine on the master branch.

There should be no change for the Disk.copy() function between rocko and master 
branch. Anyway could you have a try on the latest master branch?
