Is there any version from OpenWRT working with ePMP1000 ?
I did a little searching, and not that I know of. I believe ePMP is based on the Atheros AR9344 SOC, and if you look at the supported hardware table on the OpenWRT website, there are a number of systems with this SOC that are supported, however the ePMP isn't specifically listed. I imagine someone bright enough might be able to port it, but to what end? There are so many other systems that support it, why bother? Are there some specific features in OpenWRT that you're interested in?
Yes , I like to update the Logo if possible ?
Can I do that
It is currently not possible to change the logo. This is something a couple of customers have requested but we currently don't have plans to provide this functionality.
