Okay, that's what I thought. Thanks ! So ECC isn't ready for prime time yet. A long time ago, when we were also looking into boot time improvments, I briefly enabled hardware ECC in the kernel, but then people started reporting stray JFFS2 errors, but I couldn't find any flaw in the kernel, so I disabled it again. We didn't find out that this was an interaction between u-boot and the kernel until much later. - Werner
