Yes that seems like a good idea, not some highres pictures of the entire pcb (both front and back) would make a good addition. Also can you please: 1) Create a link named I12-tvbox from the frontpage to this page. 2) Add some notes that the same pcb is also used in a tvbox called the q5 and in some brandless boxes (with the same port layout / enclosure) 3) Add a note that the qt840a uses an ap6330 wifi/bt module where as the q5 and nonames uses an ap6210 wifi.bt module. > >> wifi chip, as it claims to have 2.4 and 5 GHz wifi.

What should I look for? I committed and pushed it May 14th, maybe you need to update your checkout ? I've just also added your qt840a.fex since the ap6210 uses wifi_mod_sel = 7 where as the ap6330 uses wifi_mod_sel = 8. >> So first lets see which wifi your board uses. > > What about my u-boot patch? Did you create a dram file for the board too? Yes, that one I had not pushed yet, but I just did, if you checkout the latest sunxi branch code, then you can do: make -j4 CROSS_COMPILE=arm-linux-gnu- i12-tvbox_config make -j4 CROSS_COMPILE=arm-linux-gnu- And you will get a u-boot which should work fine on your board too. As for your patch I've not seen that one, I guess it somehow never made it to the list. But is no longer necessary, the i12-tvbox target should work 100% for you. >>>> And also does your ethernet port work ?

Regular ping, or ping -f ? ping -f floods the line with as much packets as possible so it is a bit more of a stress test. >> My ip101a-lp also gets quite hot, can you touch yours (for a while) while it >> is in operation to see if it too gets hot ?
