Hmmm, I know they are generally quite insistent that you use a heatsink and fan
<
omnitechnomancer>
I guess finding the reset io and setting that to hold it in reset may be wise
<
etrig>
maybe set all other connected nets to input
<
omnitechnomancer>
I will have a look, there likely is since it apparently works on a z7010 which is less than half the size I think
<
omnitechnomancer>
Will also probably need to figut out how to allocate a big chunk of DMA memory on the ARM so that the FPGA can use it
<
omnitechnomancer>
Probably just add a driver that will do that at early startup or something
<
horizon>
there are kernel parameters for that or via kernel config you can select reserve cotiguous memory
<
implr>
in the dts for memory: linux,usable-memory = <0x0 0x20000000>;
<
implr>
if you just want to chop off the top
<
implr>
if you want something more complicated you can reserve a dma range

Yea a DMA range was what I had in mind

Does the parallella run okay off USB power or should I source a barrel jack 5 supply?

So in short it was not designed to run on USB power?

that appears to be about the A ports, not any B ports

I guess it's about the OTG port not the device port
brizzo_ has quit []
<

oh, it was OTG? not A?
<
zyp>
been a long time since last I looked at the parallella, still got it in a box on the shelf
<
omnitechnomancer>
Yea mine have been sitting in their boxes
<
omnitechnomancer>
but yea looking at the schematic it is about the OTG port not the other one which is intended as a possible power source
<
zyp>
I just figured that since they're talking about a noncompliant hub powering upstream, it would be about a host port

Indeed, it is a host capable port at least
