ipsec l2l tunnel between 5505 and 5540

I'm having trouble getting the tunnel up between the two devices. please take a look and tell me I've left out something silly. here is the config from the 5505, the 5540 is good as I have several other 1841's connected to the device over ipsec vpn.

Where is the other ends config?

Looks ok but you dont have any access lists allowing traffic from inside to the VPN, you have crytomap access lists to tell the vn what the interesting traffic is, it might be that the VPN is connected but traffic is not flowwing because of ACL?

do you have any logs?
enable syslog or look in the ASDM for syslog messages.
