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.

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.
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!
Deleted post.
Things working OK.
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 [email protected]. 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
Hey, I downloaded the 5.36 image and it is starting up on my BPi M2 Zero for a few seconds. Then it is printing out a message, that CPU is getting too hot and performing an emergency stop. Don’t think it’s normal. What can I do? Best Regards MK_munich
