AR750s bug with ddserver

Post by dragonlost »

Hello.

I have a gl.inet AR750s.
This router works on OpenWrt 19.07.7

I did not find a version of ddserver precompiled in version ath79.

So I compiled my own version with the gl.inet sdk.

I installed it and then launched it and no worries.
I plugged in my canon 500D then try to connect with qdslrdashbord 3.6.4 on Windows 10
The app sees the canon:
"connecting to DDServer DSLR Canon Inc. Canon Digital Camera"
But nothing is displayed and the application crashes after 30s/1min

So I'm looking for a solution to make ddserver work on my new router. ideas ?

on the first version of the AR750s the openWRT version allowed to install the version for ar71xx which worked correctly.
