Apparently while I was happily using tiny261's , mega 168's, tiny10's, etc, another programming method has snuck in...went to use a tiny816 & encountered the "new" UPDI method.

I have an ISP MKII (& of course a handful of STK500's)...but apparently they won't work with these new "tiny-1"  chips, correct?

 

Is there a low-cost programmer that will (say <$60)?  not interested in building my own programmer, though a simple mod to something might be ok.  Am using AS7 & GCC.

 

Is this new UPDI any good?...debug wire seemed like a big mess of reported problems & lockouts, so I've always avoided it.  I don't need any debugging capability, just programming the chips.

 

 

When in the dark remember-the future looks brighter than ever.   I look forward to being able to predict the future!

Thanks, though I'm looking for an actual programmer solution, usable from AS7...little nervous about using a serial port adapter as a programmer...might do in a pinch.  Telling the production people to do that might raise some eyebrows.

You're using AS7 on the production line!?

Python UPDI driver for programming "new" tinyAVR devices

pyupdi is a Python utility for programming AVR devices with UPDI interface using a standard TTL serial port.

Connect RX and TX together with a suitable resistor and connect this node to the UPDI pin of the AVR device.

Be sure to connect a common ground, and use a TTL serial adapter running at the same voltage as the AVR device.

So don't tell them that, then!

 

Just tell them, "This is the UPDI adaptor" ...

 

Simples!

 

cool

Thanks, but the link to the power debugger seems $$$...The old ISP programmers can be had for $15

I am looking to being able to program from within Studio 7, using the normal tools  & programming menus ---selecting fuses, etc

That's not the kind of thing one would normally do in Production - hence the puzzlement at your use of "Production" arguments against the pyupdi.

They actually do use studio & just get to the programming tool & programming menu (just selects tools, programming , the file, plug in the cable & hit program, plugin the cable & hit program, etc)

I am not concerned about the now...what tools can be used with studio that are in the cost range of the MKII (could be an offshore type)

With studio in 5-10 minutes you can have your production boards (say a dozen) all programmed.   My question is, can we continue with chips like the tiny816

Title:

Using Atmel-ICE for AVR® Programming In Mass Production

Name:

AN2466

Date:

07/28/2017

Description:

The application note introduces Atmel-ICE setup, driver installation, user guide of the Atmel Studio command line utility (atprogram.exe), and provide a PC programming tool project written in C#. The Visual C# example project can be downloaded along with this application note and run with the ATmega328PB Xplained Mini kit.

via http://www.microchip.com/wwwproducts/en/attiny1617

Microchip restocked Atmel-ICE PCBA such that it could be a component in a low-rate production line (pitch conversion, stainless steel contacts, pogo, BIT data via DGI)

There's a list of third party programmers; maybe one has UPDI for high-rate production.

Microchip does program AVR but not yet tinyAVR 1-series.

I have an ASIX Forte programmer here which I use for serial EEPROMs. It will also do megas and xmegas and coming soon is uPDI. I'm about to move over to using it for AVRs. Why? Because the USB drivers are benign and don't mess with all my other USB stuff unlike Atmel.

That is my question...is there a list of low-cost programmers that do UPDI & work in studio 7, kind of like the MKII clones.  Any production is low volume, maybe a few dozen here & there every few weeks.

 

Also, is there a complete list of which chips require this UPDI...in case we want to avoid (or use) those chips.  The Atmel selector page doesn't indicate what type of programming is needed.  You can sort of see it from studio, working backwards (pick a chip then see what tools are good for it)...but studio (at least my recent version) doesn't seem to have all the latest chips to pick from.

Not that I'm aware of.

Am aware of Atmel-ICE-PCBA at 50USD and the inexpensive pyupdi.

Don't drop a conductor onto any of these else it may no longer be low cost (possible loss of a PC USB host port or worse) (operate a USB isolator)

Thanks the ICE-PCBA might fit the bill...why such an idiotic generic name??...how about a model number, like programmer/debugger PROGPRO 9300A??

 

 However the manual says nothing about UPDI...it says

 

Atmel Studio supports programming of Atmel AVR and Atmel SAM ARM devices using the Atmel-ICE. The programming dialog can be configured to use JTAG, aWire, SPI, PDI, TPI or SWD modes, according to the target device selected.

Hmmmm you are correct....Interesting that they left UPDI off the list they enumerated...I suppose it was an oversight & of course the first list I came to.

 

So this unit sounds like exactly what I was hoping for!

 

Are there any drawback or issues withg this, say compared with the AVRISP MKII?

 

I looked on Digikey to purchase & there are 3 things call Atmel-Ice....one is $55, the others $99 & $140....what are the differences in capabilities of the $55  vs $140 unit.  It alsmost seems like nothing, since they refer to the same manual The $140 has a plastic case...maybe that's all??

Apparently the $100 price difference is only for a $5 plastic case & some cheap cables & breakout adapter...

 

Even on Atmel's ICE webpage it fails to mention UPDI, but mentions the other modes....strange

No enclosure and no cables.

 

The replacement for an Atmel AVRISP MKII is LUFA AVRISP.

Could inquire with Dean about adding UPDI to it or create a UPDI LUFA issue then have a visible discussion with Dean.

PDI is USART, UPDI is UART (do-able)

To an existing off-the-shelf LUFA AVRISP, add the resistor as in pyupdi; or not as one LUFA AVRISP has two 100R on the USART TXD and RXD.

Likely it's the Microchip web pages that are up-to-date :

You are correct....an interesting dual universe of Atmel & Microchip!!! I supposed any outdated Atmel pages really should be fizzled.

I'm leery of that because some of the source code zip files haven't been copied to a Microchip URL.

There's still an active webmaster at Atmel so eventually the i's will be dotted and the t's crossed.

Have a word with Alank2 about his board (see the post in marketplace) as I asked him about UPDI support.

Well, you can't connect just the UPDI pin, you also need to connect GND to have a reference. Voltage levels need to be relative to something...

Note the Atmel-ICE does not provide power to the target device, with out a source of VCC/GND you will get that error!

show us the schematic of your board UPDI does 12V is your board capable of handling that on the line?

 

Are you sure you have made the right connections? GND and VTG seem to be correct. what about RST and DATA

Ok, in this case, I think you should put Atmel-ICE aside for the moment and use a different programmer.

 

If you have an Arduino around: https://github.com/ElTangas/jtag...

If you have a USB/serial adapter: https://github.com/mraardvark/py...

 

If none of these programmers work, then we must conclude the MCU has some kind of problem, or your circuit.

never used UPDI, but flags like this seem to suggest that 12V will be used and that you have to take precautions to avoid the 12V that will be (generated by the programmer most likely) put on the circuit will harm it......

Hi avrcandies! 

I recently wrote an article on the connection and programming of "new" Attiny microcontrollers using UPDI.

https://npk-stn.ru/2019/07/19/si...

This article also reviewed a programmer with a valuable <1 $. A detailed diagram of the connection of the programmer to the microcontroller is reviewed and described.

I assume that would work using a USB-TTL dongle?

I see. It's a tutorial on how to upload a program to flash using pyupdi with a USB/serial adapter, it should be useful for beginners. However, in my experience, eventually the beginners will want to know how to program the fuses, or maybe the eeprom, so you already have a suggested theme for part IIsmiley

I worked exactly with USB-TTL dongle.
