I've been building from the master branch for a few months now and i noticed now and then that the .img file (inside img.gz) sometimes gets courrpt during the creating process, it's noticable since the 2nd linux partition created after writing the img to the sdcard is unmountable even on the pc.
when inserting the sdcard the error is:
i tried writing it several times and even deleting the partiotion table formatting etc it's the img it self, i tried formatting the 2nd partition as ext4 and got the following error (probobly on the 1st partition):
The thing is, actually 2 things:
1. the working build i have is from May 6, May 7 fails like this, i also have a build from June 2nd (fresh) also fails and one from June 10 and today (not fresh) all fail the same way.
2. copying the img.gz to .update and running the update on the build from May 5th passed and made it update but inside is the same .img file that fails to be written to the same SD.
Before the May builds i've also enoutnered this but since i'm still new at this i though it's my faults somehow.
BTW i'm building for Wetek Core (amlogic pkg) and this was the same for openelec too.
