I recently ordered an AR9331 based device from skylab. The description claims that the module supports openwrt.
I do not have a eval board for this, and powering up the module - it creates an access point to which I can connect and login to the administration page. Here is a screenshot.
The module I have contains 16MB flash and 64MB RAM, or so the manufacturer claims. The label on the RAM confirms that it is 64MB. The label on the winbond flash is illegible, so I cannot confirm that value.
When I asked the manufacturer for an openwrt firmware I was pointed to download the image for TP-Link 710N. Specifically, this was the image that was shared with me.
Now TP-Link WR710N is only 4MB flash. The most I can get in WR710N series is 8MB (V2.1). One product which has 16MB of flash is GLInet AR150.
Here are some open questions:
- Which firmware should I try. TP-Link710N or AR150?
- Which variant should I try. Factory or Sysupgrade. It seems to me the stock firmware isn't openwrt, so I guess I have to try Factory.
- Since I don't have a physical LAN port on the module, how am I going to access the module after I flash the firmware. I think openwrt disables wifi by default. There seems to be UART pins exposed which I have access to, so I could presumably use that.
- Is there an easy instruction somewhere to turn the wifi on if I get this far?
This is a competitively priced module ($9-10) with AR9331, 16MB ROM, 64MB RAM, but barely little or nothing is available on the openwrt forums on this. I think if it can be made to work with the latest releases, then it might be a useful addition to the supported devices list.
