Discussion Big News on NUON Controller Development

I'm on the list. Most exciting thing about this (IMHO):
" Possible serial communication for developers " listed as future possibility.
 
Yep and the N64 to Nuon adapter preorder will be going up in Jan on Songbirds site in Jan.
Just placed the order for the first run of boards for the final verification.

Does anyone have any details on the serial adapter other than this post:

Was there a SDK that let you load code over it to the players?

I've unfortunately never seen one of those in the wild. My guess is it's a prototype, and like all the other controller related stuff, could be easily recreated IF we had a stock of original Polyface chips. We have none. Hopefully, these new devices coming out will eventually replicate the original chip well enough that something like this could be possible. Think BLL for the Lynx, or BJL for the Jaguar.
 
First mention of a serial adaptor here!!! We are looking into it!

Not ordered yet but going to use my discount on it. Put me on the going to order list :)
 
Unsticking as we have 2 new options now so it does not need to be top of the forum all the time.

Very exciting :)

By any chance will your adapter help with software development in the near future?
I mean, if I get a FTDI (serial to USB) and connect it to your adapter, would it be possible to send files to RAM, remote execute and getting TTY output?

I'm not a pro, but cubanismo mention:
"Yeah, I'm familiar with the GDB stuff. I did a lot of work on GDB-over-USB for the Jaguar recently."
via discord.

That would be ideal! :)

Sorry don't visit the forums very often so just saw this while trying to put the full timeline together for a talk. There are a bunch of different modes the polyface chip can be put in. I found some side references to serial but no hard documentation to code to. In theory it should be possible but would need more documentation or a real device to trace to get the init seq and how the data flows. Few posts back I asked about the SDK and was hoping it had this feature and we could find one to investigate how it is done.
 
No problem, if you can please share the talk, I'm keep for some Nuon tech talks!

Not sure how helpful this is, I noticed that "NUON_Tech_Data\Offical SDK\bin\860stub" has this both the boot and stub rom, the stub rom has:
"Express Logic Inc. * ThreadX MPC860 Green Hills Version"
I'm not an EE, but it does have PowerPC core, (with Ethernet 10T like the dev kit) so I wonder if this could be reversed engineered to make a mod to make a retail unit into a development unit! Then the problem becomes how would it interface with the different Nuons.

I guess moving forward, first steps would be to find spec sheets of each unit and/or tracing points, legs, lines etc... and finding serial/TTY out.
 
Talk should be next weekend. Not sure if Carl is going to record them or not. (Will ask)

My day job I am familiar with Green Hills debuggers. Expensive bit of kit but does the job when things go to lunch in a processor for no reason and need to debug instruction by instruction.
 
Serial port update:
Digging though this data getting ready for the talk (trying to remember where I found bits of info) https://drive.google.com/file/d/1Q4WfAm9hfiWDh2Sg83zuOpm4JLTHXcnF/view?usp=sharing
There is a subdirectory for the "Serial Adapter Schematics" which has all the info to build one and some sample code that I assume is a test program for it. Looks like they put the polyface into a IO mode then drive a parallel load UART chip to generate serial. If I had to guess I bet there is not support for that in the BIOS to load code into ram. But could be wrong someone with more skill than I would have to do some digging. If the support is there should be possible to emulate it.

I think the GH debugger might be a better approach, there's no polyface to figure out.

    Also if you want mixed drinks without alcohol, there's a handful of non-alcoholic 'spirits'. Ritual Zero and Free Spirit are the two brands I've tried and they are alright. They don't have a TON of options, but they have some gin and whiskey alternatives that are fun to play with.
  • Varine Varine:
    I got a couple bottles to make some mixy drinks around holidays when I mostly want to drink, they aren't exact replacements but they are surprisingly close.

    I just got moved to unsupervised probation, so I can get away with drinking a bit now. I technically am not supposed to, but I don't think I get checked anymore. I really want to smoke weed but it scares me

    Happy Wednesday! I am not feeling it today, my teeth are bothering me, or the fragments that were left behind are coming up and it is extra painful today. Don't ever let them tell you that getting full dental implants is easy. They have to pull all your teeth to do those and apparently they are not very good at getting all the teeth out all the time.

    That is true with Dentures too. I am taking the day off and working from home. The big difference is though, I am not drinking anymore so I have a nice tea and coffee regimen set up :)
