Just purchased a ZBT-WG3526 ( MT7621A) device recently and want to add the openVPN package and multi-wan (Mwan3) in the device by myself: I'm very appreciated if any expert can help the following issues:
- How to install the development environment ? or I can download the develop VM and develop my application directly?
- Where can I download the toolchain?
- Where can I download the ZBT-WG3526 OpenWRT source code?
- How can I configure he ZBT-WG3526 hardware specific hardware, e.g., GPIO
I've experienced on developing the Embedded Linux device, but it is the first time I using OpenWRT, so I need your help.
