The JFFS2 virtual block size is also 4KiB. The size of pristine node is 4KiB data + node header. So, in uncompressed form, the pristine node can't fit into JFFS2 block if the compression is disabled. So, how does JFFS2 work on such flash :-) ? Thanks. -- Best Regards, Artem B. Bityuckiy, St.-Petersburg, Russia.
