Capture DM log over socket with AR7594

Setup

Connect LAN port on AR7594 board with Linux host
Expected to see interface similar to below

ifconfig enx00116b738e27
enx00116b738e27: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500

Run python script attached to apply filter and receive DM log

./dm-logger.py 2500 …/3/tools/logging/dm/filters/MC7xxx_LTE_QOS_filter.sqf out.dm

Run logger on the modem via adb

Capture with IPv4 socket

adb shell diag_socket_log -a 192.168.225.59

Capture with IPv6 socket

adb shell diag_socket_log -a fe80::c027:8489:aaa:5c78%bridge0

Convert captured log with swilogutil on Windows

swilogutil convert out.dm out.dlf

Notes

• The python script works on both IPv4 & IPv6 sockets
• Remember to append %bridge0 when start IPv6 logger

Test Environment

• Python 2.7.12+
• AR7594 firmware SWI9X40A_01.05.03.00
• Ubuntu 16.10
• Linux kernel 4.8.0-41
