Here's the issue with touch..

When you are booting and look at the console output, when it starts the counting (changed in the new version, btw), it is waiting for the eMMC handling to come online (/dev/mmvblk1).  At that point, it pivots to the rootfs (/dev/mmcblk1px) and the ItusgatewayImage bin is not touched again.

If refreshing the timestamp on the ELF binary image made a difference, it shouldn't even boot to the kexec() pivot.

Since you've got my latest build, from your console:

tcpdump -i eth0


root@OpenWrt:/# tcpdump -i eth0
[48431.418627] device eth0 entered promiscuous mode
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

These are the DHCP client solicit requests going OUT from eth0.  They are not actually going out though.  So.. Firewall issue?   I was reading that because it's got no IP (0.0.0.0) that it gets stopped by the WAN, dunno yet.

I'm going to need to fnd a way to wireshark the connection :(

Ah well, we'll continue and see what happens..  But if anyone knows, or knows someone, who can help em troubleshoot the networking driver issues, let me know
