Latest PiSmasher image from twitter

s.blakley86 · May 24, 2017, 10:08pm

Howdy all,

I checked out the image that you devs posted on twitter, and I had a few questions:

Does the PiSmasher have two dedicated ethernet ports as shown in the picture? Also, is there only one free set of pins (top right of picture) accessible to the user when using the pismasher? Will there be a snickerdoodle black version of the pismasher, and if so, how will it differ? If not, will the pismasher be able to take advantage of the extra I/O pins that the snickerdoodle black has to offer?

Cheers,

-Sean

Hey Sean,

To answer your piSmasher questions:

Yes, there are now two dedicated RJ45 Gigabit Ethernet jacks (routed to programmable logic).
Yes, there is one FPGA I/O bank exposed (connected to JC1 on snickerdoodle prime/black).
I'm not quite sure what you mean by "snickerdoodle black version of the piSmasher," but it's compatible with all snickerdoodle configurations. We're considering two versions of piSmasher (the one shown and a "spec'd down" version) but that's still up in the air. We have another solution in the works for those who only want HDMI out and USB.
Re: snickerdoodle black I/O, see #2.

We should have more info for everyone in our next update - hopefully later this week.

Thanks for the heads up. My statement about the snickerdoodle black version of the piSmasher was concerning the fact that the snickerdoodle black has more of the "connectors down" connectors than the regular snickerdoodle version, so I was wondering if the pismasher would have enough connectors to be compatible with both versions of the snickerdoodle. You answered that question, so thanks! Definitely curious about details on your solution that has only HDMI out and USB btw.

Can you elaborate on what PHY's, if any, are attached to the Ethernet, USB and HDMI ports? Having a PHY considerably increases the free logic available in the PL for actual designs, so this is kind of a make or break point (compare to the Arty Z7-20, which has PHYs for Ethernet and USB, but nothing for HDMI). Also, are there codecs on the line out/headphone jacks or is it expected to be driven with PWM?

Thanks,

Alejandro

The PHYs are:

Gigabit Ethernet x2 - Marvell 88E1510P (http://blogs.marvell.com/2016/10/marvell-phys-for-low-latency-industrial-ethernet)
USB x4 - Microchip USB3315C and Microchip USB2514B
Audio - TI TLV320AIC3104
HDMI - NXP TDA19988BHN/C1 and NXP TDA19971BHN/C1

Ryan, any updates on the status of the "solution" for those who only want HDMI out and USB? A baseboard with just those two things and a bunch of GPIO would be very useful to me.

Thanks,

Cameron

Hi Cameron,

We have to be careful about publicly discussing products that we can't ship right away but I would definitely invite your personal input on what you see being necessary specifications for HDMI out? Frame rates? Supported Color Spaces? Resolutions?
Some of the other examples of this don't use a framer (like the Zybo and Pynq 7000 or whatever) but I've heard a few complaints about that approach.

Ultimately the framer effects the I/O consumption negatively but the FPGA resource consumption and ease of use positively.

Let me know your detailed thoughts on what you've proposed (HDMI out + USB only).

Jamil,

After some careful consideration of what I am going to be doing with my Snickerdoodle, and realizing that the default Linux on Snickerdoodle doesn't ship with a GUI, I realized that I don't actually need HDMI and USB. Thanks for being open to feedback!

No problem Cameron.
Hopefully you are mounting the snickerdoodle into a flying robot where the extra weight of consumer I/O interfaces would be a downside :-)
