Thank you, Carlos.

Meanwhile, it appears my microSD got corrupted. Having a hard time trying to fix it.

[ UPDATE 1 ]

Got card fixed and reinstalled image. All is good now. Overall, this image works great.

Using with USB hub with 3 USB ports and 1 ethernet port.

Thanks for providing it.

[ UPDATE 2 ]

Having problems shutting down properly.

Now when I tried to boot up again, besides the CRC warning, a bit later in console I get another error message, but went by too fast to read it…then it ends up with about 10 lines of text like this:

missing environment variable: boot file Retrieving file: pxelinux.cfg/00000 Not ethernet found.

missing environment variable: boot file Retrieving file: pxelinux.cfg/0000 Not ethernet found.

missing environment variable: boot file Retrieving file: pxelinux.cfg/default Not ethernet found.

Config file not found starting USB…

No controllers found.

No ethernet found.

No ethernet found.

=>

Tried rebooting again without USB hub attached, put keyboard dongle directly into UMPC, but get same errors…

Time re-install image file again, I assume?

[ UPDATE 3 ]

Reinstalled image on card. Used device OK and did shutdown.

Now, I rebooted and it started up OK.


#23

Just tried booting up UMPC again.

Got the same ethernet error as in previous post.

Is there any way to bypass this error to boot up or do I need to reinstall image on card again?

Thank you for help!


#24

Deleted post.

Things working OK.


#25

Is it safe to do apt-get upgrade or will it break system?

Thanks for your input.

Hey, I tried to install wiringPi on this image, but every time I try: gpio -readall I get this message:

Unable to determine hardware version. I see: Hardware	: Allwinner sun8i Family
'
 - expecting BCM2708, BCM2709 or BCM2835.
If this is a genuine Raspberry Pi then please report this
to projects@drogon.net. If this is not a Raspberry Pi then you
are on your own as wiringPi is designed to support the
Raspberry Pi ONLY.

Could anyone help me with this? Using this wiringPi Port: https://github.com/BPI-SINOVOIP/BPI-WiringPi2

Thank you
