Hello again.
I got an .img file, ubuntu, that I found for the Firefly board which uses the same 3288. I flashed it onto my rk902ii and it booted, quite fast actually.
Functionality is not complete.
The wifi doesn't work - I have come to understand that the ethernet chip is different in Firefly from rk902ii.
Ethernet reports 1GB connectivity. Initially it fails to get ip/route/dns information from the dhcp server in my lan. I suspect this is connected to a message that indicates "NetworkManager is not running". If I supply the information via normal vanilla linux utils (ifconfig, route, /etc/resolv.conf) then it all works ok.
There doesn't seem to be acceleration for graphics. The windows tear and stutter when moved on the screen and youtube videos end up with some 10-15 frames per second, with processor load at about 65-70%, all cores at this level.
It would seem reading and writing onto the internal sdcard is kind of slow. I will need to check more on this, I tried to use iotop to see more details but I got the message:
---------------------
Could not run iotop as some of the requirements are not met:
- Linux >= 2.6.20 with
- I/O accounting support (CONFIG_TASKSTATS, CONFIG_TASK_DELAY_ACCT, CONFIG_TASK_IO_ACCOUNTING)
- VM event counters (CONFIG_VM_EVENT_COUNTERS)
--------------------
I haven't been able to test sound, I'm using a normal lcd computer monitor with a hdmi->dvi adapter cable, I'd have to take the box home to test it with a tv for sound. I will do this in the following couple of days.
I hope this information to be useful for further development of linux on the mk902ii.
Do I have the the ability to make a backup with RKBatch Tool ?
