Phil C's Raven build

[PhilC]

Well, that's just plain annoying, it crashes with all versions of the firmware I have, as does my original Diamond card, yet the GD5429 runs great in my Raven all day long.

[PhilC]

So I am wondering, since @agranlund has the same Diamond GD5434 card as I do and it works on his system, what the differences are for my config and his.

All I can think of is that I am using a ATF1508AS-10 instead of an ATF1508-7 and am using the previous version of the firmware as the latest wouldn't work for me. So I have ordered a couple of them directly from from Microchip as that seems to be the only place that has them now. Other than that, it's likely software config causing the issue.

So I've built another of the Pine VGA boards and this one does boot to TOS on the Raven but also locks up. I do tend to get different results with different bios versions, so just trying a few of those now to see if it fixes things.

Do the cards work OK in a PC with DOS? Are you sure it's the Raven's fault, and not the Pine either PCB or bios, or dac?

[PhilC]

@Mikerochip yes they work fine in my PC.

The different bioses do have an effect but only to graphics quality etc typically or make the card not run at all.

The Diamond card is the same as the one @agranlund uses.

I'll double check what versions of ATF1508AS + ATF22V10's I'm using when I get home this evening.

About the firmware, is it NESSI_250714.jed that isn't working for you and you are instead using NESSI_250627.jed ?

[PhilC]

@agranlund I think that's the case but I'm unable to verify as my windows pc died on me last week and I'm slowly replacing it with another one.

@PhilC, these are the ATF chips in my computer:

Code: Select all

Nessi:  ATF1508AS-7JX84
Narnia: ATF22LV10C-10PU
Iksi:   ATF22LV10C-10PU

There are no deliberate reasons for why I have 22LV10's, I didn't even know until I checked just now
Possibly a "wrong" order, or maybe I had those at hand in my stash of stuff at the time.

I'm using Lattice 22V10-7 Gals but have been from the offset without issue. the ATF1508AS is the 10ns part, so i've ordered a couple of 7ns parts from Microchip direct.

What sort of price? The ones I have, are 10ns too. I'm *really* interested to see if they make a difference.

I got mine directly from Microchip too. Bought a few since the PLCC versions are now end-of-life.
