Do you really mean to return from the main imls function just because one image has an error? By "use return" I meant return from the subfunction.

This return only corresponds to the situation when there is an error returned from nand read routine. In that case, I don't think there is any use reading the NAND any further.

Just because one page has an uncorrectable error doesn't mean the entire NAND is bad. Note that this is different from what you currently do if you get an error on the initial read where you look for a header.

Yes, I got your point.

I would now not announce the uncorrectable errors as they may hog the whole stdout and still continue to work for the whole NAND device. Please check the implementation in v4

I'd rather see errors be announced, with some reasonable limit on how many (and a message indicating if further errors exist that were suppressed).
