RetroPie working with CM3 and Media Stick

[ESteid]

If anyone was wondering I have having good luck running retropie on a CM3 and media stick.
I also have Kodi installed as a port and it streams great.

That’s great- thanks for the info. How are you powering the stick- via power supply or using a USB port on the video monitor? For each use case (retropie and Kodi) what do you have plugged into the media stick’s two USB ports?

At home I am powering the device from the USB port on the TV. It powers it just fine.
I have a wifi dongle plugged into one port and a USB Gamepad on another.

I brought it into work to show it off and used a 2a wall wart and otherwise the same setup.

I don’t need the wifi adapter when only using Retropie but I pretty much leave it in all the time.

Hardware:
Edimax EW-7811Un WiFi dongle.
DoTop Generic Super Nintendo Controller
22inch Raspberry Pi power cable with switch.
Generic 2a 5v wall wart.

Hi,

Please could someone help. I have a Media Stick and a CM3 but seemingly nothing is working. I can get the Media Stick to flash that it’s in eMMC flash mode even when there is no CM3 present! When I run rpiboot my Ubuntu just sits there with “Waiting for BMC…” and the device seemingly never enumerates.

At the moment I have no idea if I have a faulty Media Stick, a faulty CM3, some combination of both or something else.

Any help would be much appreciated.

Thanks,

I would check how you are connected to the module. I originally had a ton of trouble powering the module and sending the OS all via the USB.

I was using a rather long USB with a button on it that I typically use for the rPi’s. But that didn’t work for programing the CM3. I needed to use a very high quality cord less than 1 ft long.

WD recommends using a powered hub as an option as well.

Not recognizing CM3

Hi, I’ve also found the CM3 to be more difficult to be discovered by RPIboot using same setups where the CM1 was 100%. You might try using a powered USB hub between the media stick and the host computer (and short, low-resistance cable between media stick and hub). Sometimes rebooting the host PC has helped in my experience. If you (or others) would like to help me investigate this area, please send me an email (dave.chew@wdc.com) and I can send some hardware- CM3, media stick, CM-to-SATA ada…

Brilliant, many thanks, I now have a running CM3 in a WD Media Stick!

I found a short thick USB lead, which I naturally assumed that as it was thick must be of great quality! but still no joy. Then I dug out my old D-Link USB 2.0 powered hub that I knew could power a small town! and voila! life. I guess my no name USB 3 “powered” hub was not man enough for the job.
