Thanks, Everyone, for participating today. I probably only saw a small fraction of what you were posting, text wise. It was something that at the end of the day it started working. I really need to review what's up with those resistor settings.
Anyway, I've got one unit that I'm taking back home to evaluate. There's really not that much to test, just the analog hookup and the PLL.
Hopefully, in a week, we will know if this is a go or not. I hope it turns out to be perfect, but all those delays scared me today.
Big thanks to everyone who has taken an active interest in P2, both past and present since it has been such a long haul. Together with the live streaming it makes it so much more exciting and fun!
I had to turn in 6:00AM my time because I had to be up again at 8 so I was a little bushed for much of the unboxing and testing. Tonight though I will go to bed earlier and get up at 3:00AM or earlier so I can follow along with my FPGA running.
BTW, it's a holiday here on Monday, maybe because everyone is so excited about P2! But if I get a couple of chips I will make up a board and send it off to Melbourne where most of the "Oz Prop" people are. I know you guys will give it a good hammering.
I suspect that lowering the clock more won't really help either. That's the nature of finer grain built for speed - its static leakage is higher.
Certainly, some real Icc/Vcc and Icc/MHz graphs for P2, will be very interesting to see, and even some overclock Max-MHz/Vcc envelope tests, to see how much margin is in the spec.

We use those same extech 382260 (Manson SSP7080 here) 80w lab supplies, they're really nice because they display in mA rather than 0.01's of an Amp, and that captures a lot of detail, for example when the P8x32A is booting and its around 2mA, and post boot it'll climb appropriately, but the extra digit is really helpful for diagnostics.
Manytimes the display today was close to zero, and given how i trust them down to low mA that bodes well for static leakage
Saw the 75mA as well commonly - lets wait and see what was driving that. Some smart pin modes will burn energy

That would be great Peter!
I might treat myself to a new hammer just for the occasion.

What with all the stream outages I missed the moment when the P2 came to life. Grrr...
I popped the bubbly anyway
Congrats and well done everybody.
Have to sleep now...
I missed a lot, but saw that. What a relief. It lives!

I think he should do a live feed too for the first try, keep it rolling...

That's 25MHz and one core only ? - hopefully, it was less than 75mA ...

And thank you for your P2D2 effort. Bravo!
0 PIN 1 MHz.. yeah, I can definitely see the use of having Tachyon available! Good job, Peter!
Now I'm wondering what happened.
Did I really see an actual P2 chip working?
Did David and the ED 209 machine beat Chip's hand soldering?
Did Ken really play Aka Bilk on the clarinet?
Was it all just some weird dream?
It's kind of hard to explain...
Congratulations to Chip and the "team from OZ"!
C.W.
Congratulations to Ken, Chip and the Parallax team.
Ken was smart to have some entertainment lined up while we panicked...
And thanks to Peter, Cluso and all the other external contributors and testers!
which segment the clarinet part is in?
...if only I could get my lazy Smile to redo it properly and release it
