R01 with a waveshare compute module Poe board

Hi,

I cant get the r01 running with the waveshare compute module Poe board.

I recently received my r01 that I ordered together wit a uconsole. Since the uconsoles are not shipped yet I got the waveshare board to thinker with the r01.

According to the sunxi wiki the waveshare board should be compatible.
It is however not working for me and I am looking for way to figure out if the r01 is broken or the IO-board.

Here is what I tried

  1. I flashed DevTerm_R01_v0.2a.img.bz2 using balenaetcher to a 64GB sd-card
  2. plugged the r01 and the sd-card in there corresponding slots
  3. checked for the jumper to disable POE
  4. connected power via USB to the power USB port

The red and green led turn on and stay on. No flickering.
I can see on my USB power supply that everything pulls around 0.3 amps. Nothing else is happening. No video out, no network traffic, nothing on the UART.

I also tried a 32GB sd-card, two other usb cables, 2 other usb charger. I tried POE as well.

Am I doing something wrong?
Is the IO Board not compatible?
Is there anyway to tell if the r01 is ok? Is there anything I could measure to verify that the r01 is not broken?

Thank you for your help.

Did you manage to get the R01 core running on the Waveshare board? If so, care to share your experience?

Did not try in a while, but it never worked for me.

My R01 is not broken, it works in the uconsole

reconnect R01 to uconsole, plug USB ethernet adapter and make sure it does work (this is: is being managed by network manager, gets address via dhcp and is brung up upon boot).
I have Waveshare’s CM3 IO board plus and also - no video, no serial etc but usb works and currently i am trying to work around this crap with UART but methord with usb ethernet works for me (after some fiddling with network manager).

sounds promising.
I’ll give it a try once I find the time.
But this mean, that some of the pins on uconsole and the wavershare board are wired different?
Or do we need to supply some other settings?

of course no!. R01 is compatible with CM3 form factor but you know, 75% of useful pins are GPIO. You can configure them as you please and plug in something like AXP power management chip which is obviously lacking on the Waveshare board. From what i’ve read somewhere here D1’s framebuffer driver doesn’t support HDMI output, only X driver does(but i haven’t confirmed that yet).
i don’t get what’s the problem with uart, yesterday i’ve spent literally whole day messing with IO board’s cp2102, standalone pl2303s and handful of usb2ttl adapters and my greatest achievement was ability to send data FROM r01 but not the other way around. it’s bumpy road, not gonna lie
