Re: Compute Module Test Board

Thu Jan 08, 2015 1:26 pm

ok just to recap I can confirm that usb and ethernet now works :) :D further testing is now to check if i can get the full 480mb of usb2.0 and that the ethernet can get close to the 100mb throughput. this is to determine if the routes i did in eagle cad are correct :lol: :D

A lot of lucky, what factory or did you use the web to make pcb and assembly?
Thanks

Ping statistics for 192.168.0.188:
Packets: Sent = 12205, Received = 12195, Lost = 10 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 2000ms, Average = 0ms

the 10 lost was me unplugging the power accidentally :oops:

I also Tested throughput on the Ethernet side and it averaged about 8.2MBps(~82mbps) which is about right :D

more testing tomorrow. :D :lol: 8-)

Hi, I'm interested in what factory you send the proyect for the manufacturing and the assembly of the components.

Hey guys, I thought I would share that I am about to release the eagle cad files for the Test Board over the next few days. Please note that this is for the CM Mark 1, As there isn't any details currently for the Mark 2 at this stage, Once released i will update the test Board accordingly. :D

So watch this space :D

Thanks for this Briarios, it will be a great help.
Could you post the library files you used in the board design?
I would like to use a right-angle SODIMM connector, and having the libraries should help.
Thanks again,
Nicholas

Hi Briarios,

How do you perform USB boot and initial write to the flash IC with your design? I suppose that it is not possible and we will need the official CM module mother board or another custom designed board.

Ivo Milev

Hello Ivo,

I had origninally Included it in my Original Design, but had issues in getting it to work so I had removed it. The Current design is designed that in its current form you can access a flashed CM without too much work. I have released the files so that people can use these designs as a base and work on from there by adding in things like HDMI, USB Boot and adding in things like the I/O Headers to their projects.

hope this info helps.

Briarios.

Hi Briarios,

Thanks for the clarification :)

What kind of issues you got for USB boot? I mean , did you use USB mux IC or you tried without the mux, i.e. with jumper selection?

Best Regards,
Ivo Milev

Jumper selection, i couldn't find a Eagle library like or similar to the IC, so i had left it out for the sake of simplicity.

Hi I don't know if you're still active on this project or on this forum but I'm currently working on a project using your testboard as a template. However, I'd like to add in HDMI and a wifi module and I'm not sure how I might approach this as I'm still new to PCB. Any suggestions will help! Thanks!

Hello I am still active on the forums just on another project i am doing at the moment. as with adding in HDMI and wifi, they are a little hard to approach so i will try and help you with at least HDMI,

for HDMI you will need to make sure that the data lines are set to a 100ohm differential like Ethernet and ensure that they are short as possible. to set a 100 ohm differential in at least eagle cad I did it this way. set the thickness of the trace to i think it is 0.006 inch and set the dot spacing to 0.006 inch as well that way it will almost match the differential to within 10% which is inside the error rate for HDMI/Ethernet.

As for the wifi I will say i haven't looked at that purely as wifi modules are more expensive as a usb based wifi module.

does this help?

Hi Brian,

Where can I get a bare or populated test board?

Hello Ian,

your best option is to download the Board files and then send the Gerbers to your favorite PCB House for them to do the manufacturing. As it will be really expensive for me to send you a board :oops: to give you a quick idea the cost of a single populated board is about $110-150USD as that is what i get charged from the PCB house including the shipping to Australia.

Hey Briarios,

My startup is developing a product based around the compute module and we'd like to thank you for the test board, it definitely seems like a viable alternative to anything else available at the moment. I was wondering if it would be possible to get in contact with you in regards to potential changes that can be made to the board?

It would be fantastic if you could drop me an email at black.ai@icloud.com!

Cheers,

Sebastien.
