So todays progress... wifi working .. i can get 1.9Kb/s download... woooooo!
But more importantly i can get onto Aminet and I can run WookieChat.. #Amiga-IE on Freenode being my destination.
I did some measurements... I have missed 2 wires from the edge connector to my CPLD.. EXP_BR and EXP_BG.. Akiko does some DMA cycles where it asks the CPU to STFU.. and I dont handle this... So i think thats why the drive doesnt work. A rev2 will be needed.

Re: The TF330 is here
I guess I will use my TF530 to test which cpu will run at 50 mhz.
EDIT: just plugged in a 33 mhz and it runs at 50 no issues. Yet I couldn't get a 25 to run at 33. Go figure. The luck of the draw I guess.
EDIT2: nvm, it crashed after 10 mins :)

Re: The TF330 is here
I used a 33Mhz Plastic for my 24 hrs soak test. Perhaps more likely to work in the TF330 with its clock switching to 14Mhz.... gives the CPU a break here and there maybe?

Re: The TF330 is here
Thanks for the great work Stephen and everyone else on the project.
I was wondering what performance we can expect from the TF330. I remember to have seen something around the lower 6000's "dhrystones" in sysinfo. While it's a considerable boost obviously, it's still a bit behind what 030 boards can do afaik (8-9000k). Is it due to "safe mode" that I think was mentioned, or perhaps the 50 - 14 cycling? Do you think the final rev can improve on this?
I'm getting one anyway, just curious. Please keep up the awesome work. :)

Re: The TF330 is here
Currently getting 6813 Dhrystones with the ram in dumb
Safe mode. Expecting 9000 once burst mode is enabled
The 14/50 cycling makes no difference as the cpu would be in wait states either way. It just makes transitions more reliable.
I’ve not worked on performance because I had a demo with the board today. It ran for hours without a single crash.

Current benchmarks.. no burst mode yet...

Re: The TF330 is here
Aw man.. i just blew up the CPLD... i think 12V went through it :(

Re: The TF330 is here
Aww...What's happened? You was trying to add flywires from riser? Yeah, same is on A2000 CPU Slot - all voltages present, so need to be really careful...terriblefire wrote: 09 Dec 2018 21:28 Aw man.. i just blew up the CPLD... i think 12V went through it :(
Hopefully Your new CD32 isn't damaged...
