Thanks Michael, and appologies to Eddie.
what I meant was that jessoff had posted the information, no offense (and
thanks) to Eddie if he wrote the code.
I was hoping to recover the situation with something less drastic that
erase_all but if that's all there is ....
Is this a known issue with yaffs2 ? Would I be better reformatting as jffs as
an earlier poster is doing?
best regards.
