P10 Panels Every Other Row Works

[CraigB]

I thought that I would jump into the P10 panels this year. I have 6 P10 panels that I have set up 3 across and 2 high, using a BBB and Octoscroller. In testing through the FPP all of the columns work, but only every other row works. Photos are attached.

I am using a 5 volt 300 watt power supply for the P10 panels, and a separate 5 volt, 2 amp/120v power supply for the BBB.

Has anyone come across this before? Any help would be greatly appreciated.

Thanks,
Craig

Yes I've seen that happen if you buy the wrong P10 panels.  Were those listed as "Outdoor"?  If so the scan rate is usually one that is not supported.

I bought the P10 Indoor Matrix Panel Kit from DIY LED Express in January at their pre-season sale. Received them about a week ago and just had a chance to start playing with them. Their description states that they are indoor panels.

You should try my latest BBB image which allow selecting the various panel types and scan rates.   Someone else had the same issue and said my latest image worked for them.

I have Version v1.9-50-gfe8e9a5 currently installed on the BBB.

I had the same problem with 4 panels. Updated to Dans image and the problem went away.

I just installed the FPP v1.5 BBB SD image and same thing, every other row, same rows as before.

In the test through FPP the colors cycle, but white strobes. It previously did the same with the white.

It needs to be my image.  I'm on vacation so don't have the link for instructions, but look in the beaglebone section of the falcon forums.   Link to download would be

I downloaded and installed Dan's image (v1.9-dkulp-15-g8170ec1 (bbb-jesse branch) and it fixed the every other row problem. Then output 1 would not work, but output 2 does, so I rearranged the panels to use output 2 (screenshot attached), but now the two rows go opposite ways (photo attached).

Am I missing something?

Try Top Right or Left instead of Bottom Left

Just a note:  if you are only planning 6 panel matrix, I'd STRONGLY suggest using multiple outputs.   At least 2, preferrably 4 or even 6.    The refresh rate will be significantly better and panels will be brighter with shorter chains on multiple outputs.   

[CraigB]

There are only two choices, Top Left and Bottom Left, neither makes a difference.

I originally had the top row of three on output 1 and the bottom row of three on output 2, but output 1 seemed not to work after the upgrade. I have just ordered longer ribbon cables, when they arrive I will try multiple output configurations as suggested.
