Subject: Re: data  loss on jffs2 filesystem on dataflash
Date: Thu, 15 Sep 2005 09:39:08 +0200	[thread overview]
Message-ID: <4329251C.7050102@mw-itcon.de> (raw)
In-Reply-To: <432817FF.10307@yandex.ru>

Thanks for your help!

I found (at least partly) out, whats happening: Some parts of code are 
relying still on the assumption, that the erase size/sector size is 
fixed to a power of 2.

Example nodelist.c:
len = ofs & (c->wbuf_pagesize - 1)

So the jffs2 code is broken, if it *should* support erase sizes which 
are not 2^X.

Best regards
Peter
