I use the example of serial relay site and the cutecom to connect,
sending commands but I have no answer. I know it is working because the sending ATD98989898; and binding is achieved. But the answer does not come on the screen.
I couldn't help but notice that the Goldilocks is both out of stock and expensive.
Is there a market for a Goldilocks type device (with a cheaper dedicated USB to serial) that brings out all the IO in a way that is compatible with the Uno R3 layout?
I was thinking of breadboarding a Goldilocks like device and having a play. I would be aiming for a £15 to £20 price range so that people could buy one. I also like the idea of using a DIP in a socket so people could program one up and then stick it in their own design without the rest of the board.
The biggest problem I see is getting it officially into the IDE.

Obviously, the boards are selling so someone thinks they are worth the asking price.
I believe that Crossroad's original Bobduino 1284 has the UNO-ish headers. BobuinoRev17
"Expensive" is in the eye of the buyer... Some people do not wish to assemble and some prefer to buy tested, known working, hardware. I purchased the Bobduino blank circuit cards and did my own population to about 70% ... Just for my own needs. This made the package remarkably affordable since I buy the1284s in 25 Qty.
The way I read the Freetronics page, they sold some Goldilocks and then stopped while they reconsidered doing some other 1284-based board. And they haven't started again. But I guess someone could ASK whether "out of stock" means "waiting for the next set of boards" or "not being produced right now."
I'm sorta happy with the Crossroads "ATMega1284P Duemilanova-style board"; not so feature-packed, but being mostly TH construction, it only needs to keep a PCB alive, as opposed to a full SMT assembly process. http://crossroadsfencing.com/BobuinoRev17/index.html
There is also the "Wildfire" board, which is the same price as Goldilocks, but also includes c3000 wireless and some other stuff. WildFire v4 | Wicked Device Shop
I don't understand why the 1284 isn't more popular. But I guess I didn't understand why USBBitWhacker wasn't more popular, either...
Well, if 1284s appear in China, and one (all?) of the Chinese Entrepreneur Companies start manufacturing them, then they'll get cheaper. Meanwhile, you have to put up with the higher costs and margins of the smaller companies, or do a lot of the work yourself. I see that OSHPark has a number of bare 1284 boards, including a clone of Crossroad's "stick" version (~$12 gets you three bare boards...)

It appears from observation that the Chinese only go after Arduinos that are proven popular and fully supported (Arduino, Sparkfun, Adafruit.). They have little stomach in speculating and absolutely no desire to support anything. Since Arduino never supported the 1284 officially, there does not seem to be any driving force to introduce a defacto 1284 standard.
In thinking about the current state of 8-bit AVR, there does not seem to be great interest in an official 1284. The 2560 Mega generally provides everything except the additional 8K of SRAM and more I/O than the 1284. It is also hard to justify a grass roots effort for a 20K SRAM 8-bit AVR when 64K STM-32 boards are coming in near the $20 price point! Most people that want a 1284 Arduino are quiet capable of building one themselves and others are served by the Bobduino and Goldilock offerings. I bought a tube of 25 1284 chips a couple of years ago and still have the majority of them in their antistatic home.
I think that Jon and the team there are busy with some other things so the 1284p project is somewhat waiting on me to give them some direction, and I've been very slow with the next revision. But, I can't really speak for them.
There are a couple of things that I'm not happy with, as the original designer, and will be changing.
Reverting to a REAL FTDI USB-Serial interface is one of the major changes. The Arduino team had this right with the Duemilanove, but imho then went astray. Other manufacturers have reverted to using FTDI.
There are a lot of other suggestions on the Freetronics forum about improvements and / or simplifications. It is likely that there will be several versions of 1284p boards next time around, to meet people's requirements.
I'm working on a "Goldilocks Analogue", which has dual DAC with both headphone amplified output (AC) and buffered DC outputs. This will be the "high end" solution.
There will be a simple device which will have 16MHz MCU crystal, and all the other features stripped off just to give a UNO functionality but with 1284p MCU capabilities and extra prototyping space. Sekrit code name "Baby Bear".
The pricing is based on the BOM that is put into the devices. Typically, it costs about 100% mark up of the BOM cost to produce some kind of product, (and then you get issues like the Geek Ammo MicroView $58,000 lesson...) and the guys at Freetronics have to earn a living by selling these devices.
Hopefully, I'll have a final Goldilocks Analogue prototype ready by January 2015, and can use this as the basis for another crowd funding run, which can also trigger a Baby Bear production run at Freetronics too.
I was thinking of making a voltage switchable board, as the MCU can run at anything from 1.8V to 5.5V. As my CH340 boards have a switch I can't see why you wouldn't.
I was thinking of using a CH340 chip but your right, if I just bring it out to a header, people can use what they like.
As for using a DIP and socket I was going to do that also.
I like the female headers, to plug shields into, but take your point. We do an Uno clone that has the female headers but also comes with male headers you can solder in as well.
A board could be supplied with a set of both and then the user can solder it up.
I would also use a crystal rather than a resonator.
Should there be a resettable fuse on the power to the MCU?
ChilliTronix:
Many thanks for the heads up. I may prototype something... Mind you I will have to order a few extra bits in.
Just to chime in...
what would you say is a potential advantage of a new design over the three offered by Bob?
I use his Bobduino (full version) and it is great. I have not played with the chewing-gum stick one, but it appears to meet the needs of a minimalistic 1284 board. Boards are rather cheap to produce these days, but I'm just trying to differentiate why another board would be of benefit? Whatever the design, it absolutely must subscribe to the new core specs, IMO.
For "my" clarification, how would one NOT subscribe to core specs?
I was standing at an intersection and looking down a road where some weird header was placed on the board. Or some strange bootloader that subscribed to an alternate UART or maybe the on board LED was on another port. Or... heck, I don't know... I was just making a statement and confess I was completely sober while writing my piece! I write much better when my neurons are bathed in a bath of single-malt Scotch. Not adhering to the current core could be nothing more than linking to another core to install. Just look at the mess with the tiny85 until that got straightened out.
Seriously, I really do not care what he builds and tries to sell. I just do not see leading someone down a road thinking that there may be a market by tweaking this or bending that. Most of us 1284 guys can easily create our own boards - if we wanted to. Many of us have purchased from Crossroads who has a small inventory that seems to get replenished from time to time but I do personally do not think there is a huge market in this kind of product. Newbies are not close to the need and we old-timers move sideways and shuttle over to whatever chip-du-jour fits our fancy. I hear members saying that Bob's board is too expensive and I know that stuffing a board, soldering, and testing takes time so my feeling is that Bob and his wife are not getting minimum wage; rather, I think they are doing it for the community.
My opinion is there is no serious market for a 1284 board beyond what is currently available. But I hope I am proved wrong - I'd love to see someone hit the big time with a creative design. I am truly sorry that I rubbed your sensing whiskers the wrong way but I certainly was not trying to antagonize you (or anyone) in the forum.
