Brilliant idea! After trying to figure out why networking stopped (note to self - don't accidentally disable PCI Interrupts) I got NFS Root working as well and created /bin/test_init as: #!/bin/sh /bin/echo hello > /tmp/test_hello and set the kernel command line init=/bin/test_init and lo and behold it created /tmp/test_hello exactly as expected (well, the kernel then crashed 'cause init died - lol) I then created a jffs2 image from the NFS Root and got the same result Very happy :) > code is executing as expected at least.

I think I can debug it using NFS Root Graeme _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
