Re: [Gumstix-users] Problem with reboot after flash write with jffs2

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Ok the same problem with the new version installed in flash.
Did restart Linux severel times and mounted the jffs2 (mtdblock4) and did
make a read of the content.
No problem, but after the first write to the jffs2 the board were unable to
restart.

Let me know if its working for you.

Thanks

Best Regards
Benny
