Build vim2 firmware including root support

Maybe you could try a firmware change, maybe a newer version ?

I’m not a expert on doing this plus I haven’t got windows on my computer it’s a MAC I’ve got Ubuntu on it usually I watched videos on how to do this but there’s not much on how to do this do you know why it keeps restarting or rebooting could it be with something to do with android I’ve got nougat 7.1.2 what’s the latest version for the vim2 would I need to upgrade it to a latest image

I saw the latest was nougat 190518 was the latest available image

the burning tool is available for Ubuntu too,

Hope it helps :slight_smile:

When did this image come out this year

nope, 18th May, 2019 19 (rep. year) 05(rep. month) 18(rep. year) so it is 190518

I have no way of knowing what is causing the issue, be it hardware or firmware. Unfortunately, AMLogic has not released new SDK for the S912, so no new firmware exists, as developers depend on new AML SDK to make improvements.

You may want to try superceleron’s custom ROM, it offers improvements over stock firmware.
As you have already tried a different cable(power), and a different power supply, flashing firmware may be the only solution left before hardware fault becomes a consideration.
For testing, disconnect unnecessary USB devices to insure they are not to blame.

specify for us the characteristics of your power supply?

It’s khadas plug and power cable it can’t be that do you know how many amps the plug as got

Do you have an original power supply from Khadas 5v / 2A?

Yes I have I’ve just another message saying should have a heatsink and fan I’ve got all of the parts and two khadas cases but never used them

do you have a bare board at all? then the processor can warm up, and go into reboot

install radiator!

well it shouldn’t get that hot, it might crash but reboot is a whole different story, but yes one should not keep a bare board, very dangerous, One way trip for your SBC to heaven

100% agree on this.

I assumed heatsink would be mounted. The S912 can produce a lot of heat. Depending on the environment and CPU load, without heatsink and/or fan, the S912 can overheat. That can cause
SoC throttling which reduces performance, but worse than that, repeated overheating can cause system instability(reboots, etc.) and significantly shorten component life.

Is the Thermal instability that high ?, hot enough to reboot, why is it thermally that bad ?

Yes, dropped my keys on one of my unprotected VIMs, I was very lucky it was not connected to power and was not physically damaged. I got lucky.

keep your SBC’s safe mate :slight_smile:, I don’t think “Apple care” covers it, nor does “Khadas care” exist, to take care of it :laughing:

@MacThomas62 you better make sure that your device hasn’t undergone thermal stress by now, put that heatsink on as soon as possible.

I have not ran the VIM2 for a while, but if I recall , during sustained use it can get pretty hot without mass or forced air. While I continue to suspect power could be the issue in their case, without radiator or fan, heat could be more of a factor.

In my tech space(a.k.a. the cave), ambient(room) temps can be 35c and higher. I don’t run any of my arm devices without radiator and/or forced air.

yes is recommended to use a heatsink on a s912 as it gets really hot, i do even say that in my rom thread.

Ho and you can buy raspberry pi 3 heatsinks, they cheap as chips… i use one in my Vim1 and Vim2.
They good enough for the job.
