Actually , there is no display connected for the logs because my computer is too far away my tv set . Is it important ??

Thank you for you help?

Please revert back to factory firmware, and flash your self compiled kernel.img and resource.img to see if it works.




BTW, your kernel log is strange. We do not have "D1:camsys ..." lines in normal boot.

Hi all,




i solved this problem by building a full upgrade.mg file.




I got a new problem

Wired Network performances are very very poor. Same as factory image.




I tried some other TV Box images and i found one , i dont remember which one, that offers good network speed.




Which side must i check , kernel or software ? My image is based on the latest SDK provided by Firefly.




Thx for return

Hi Guys,?




i done iperf test on saturday , here is the report i got about 3,5 Mbits/s on a gigabyte switch (which work correctly with other devices like my ps3 and ps4) and i got 95 MBits/s when plugged on a 100MBps port of my internet box. I got about 30Mbps with wifi.?




I think there it is a kernel bug with mac part ....

is it possible to force 100Mbps Full duplex on the board with android ??




Thank you for return ??
