Hi MCUDude, my SerialUPDI seams not working

For SerialUPDI programmer

Using Arduino IDE or directly from the command line avrdude, this is what spits out:

C:\updi>avrdude -c jtag2updi -P COM8 -p m3208 -U flash:w:ELS_A.hex
avrdude: jtagmkII_getsync(): bad response to sign-on command: Unknown JTAG ICE mkII result code 0x01

USB cable checked, power LED on, set as UPDI programmer.

Any idea why?

When using your commands:



avrdude error: cannot find programmer id serialUPDI
or
avrdude error: no AVR part has been specified; use -p part
(Averdude 7.2)

After adding some comments, this seems to search for the target:
C:\updi7>avrdude.exe -C /updi7/avrdude.conf -c serialUPDI -P COM8 -x rtsdtr=high -p m3208 -U flash:w:ELS_A.hex:i -U eeprom:w:ELS_A.eep:i

I am sure the device is ok, your work shows top-notch. My assumption is that I am doing something not in the right way. Anyway, you can develop a bit the guidelines on how to use the device.

(Update) All working now. Thanks, Hans.

Hi, and thanks for the review!
I test each and every programmer before I ship them, so the issue may be something else, probably on the Avrdude side.
Try using -p serialupdi (non-capital letters).
Regardless, I'll send you a PM to see if we can sort out the issue.

Best cheap tool for UPDI program and debug

For microUPDI programmer

A great little cheap tool, I am using this to debug an ATtiny814 and it works excellently, with full Atmel Studio integration.

The inbuilt level shifted serial interface works great as well, and is very handy for debugging the capacitive touch interface using Atmel's "datastreamer" built into the IDE. Theres some helpful status LEDs as well, and the whole thing is nicely compact.

I previously used pyupdi based usb-serial options, and while these program fine they lack any form of debugging or a seperate UART interface. This tool instead is recognised immediately by Atmel Studio, and includes a neat hack so it works with any UPDI AVR rather than being device locked like the Atmel Xplain boards.

The added "32U4 ISP" header on the underside is handy to reprogram the Arduino if you (like me) fiddle around enough to accidently brick it.

An option for a few more dollars with level shifting of the UPDI line and some input protection would be nice, as well as maybe changing the UDPI VCC pin from an output to a VCC "sense" input instead which is more commmon on dedicated programmers (e.g. J-Link or STLink). Given how expensive the official ATMEL-ICE tool is at $100 without a case, there is definately more room for something in between.

Really well designed

For DIP-40 Arduino compatible development board

I've used for developing programs and (with a bootloader) programming chips. It's a really well made and designed board, I prefer it to official ones like the Uno.

The only improvement I can think of is if it had a ZIF but the same thing is true of the official boards.

Thanks for the kind words!

There are a few reasons why I left out a ZIF socket on purpose. The board would be a little thicker, so I wouldn't be able to use the cheapest airmail option anymore. It would also bring up the cost. If you want to use a ZIF socket you can actually insert it straight into the existing DIP-40 socket!

Works good with other Firmware

For microUPDI programmer

Thats a very good shield to generate a UPDI programmer from a chiep Arduino Pro Micro Bord. But it works only 1 time with documented firmware. I progammed the Pro Micro Bord with original firmware from Atmel Studio7 (medbgupdi.hex) and MCUdude's modified EEPROM file. Now it works well

Solid.

For ATtiny Arduino compatible development board

A great assist for those finicky 13A projects that till now have been held together with fishing line and staples. All the pins and all the options in one package. Much enjoyed!

good looking board

For DIP-40 Arduino compatible development board

Haven't had much time to work with it, but looks very well made and is as described. Shipping to the US was in a reasonable amount of time for the distance, and very well priced

Awesome adapter board for UPDI programming and Serial USB

For microUPDI programmer

Works great! Great board design. I am able to program a ATtiny1617 (and other Series 0/1 chips) and do serial communications from the Arduino IDE, all from the same USB connection.

quality, solid, construction; clearly oriented to developers

For DIP-40 Arduino compatible development board

Overall:
quality, solid, construction
clearly oriented to developers

Benefits:
A. MCU is socketed allowing easy replacement; so (a) can be used to re-program MCU IC's and then relocate them to another target board, (b) once the MCU is corrupted it may be easily replaced, (c) different AVR ATmega DIP40 MCU may be used (in my case used ATmega1284P).
B. Beyong ISP has also JTAG header connection, allowing professional debugging, subject to debugger device availability (in my case used Atmel-ICE device).
C. Has switchable 3.3 and 5V selection
D. Is already equipped with external 16MHz crystal (no need for upgrade)
E. The GND and Vcc pins are accessible via separate multiple pin headers allowing the developer to connect more than one jumper wires (typically required in projects)
F. The pins allow connectivity with both female and male jumper wires. Very convenient, accelerating development process.
G. On board annotations are rich (every single component and pin is annotated) and easily readable without ambiguities (almost, there is no need to resort to the schematic diagram)
H. The on board diagnostic LEDs allow the developer to observe all basic signals, as PWR, diagnostic-LED, Rx and Tx.
I. There is an on-board trimmer, to allow easy/direct development of "adjustable" funcionality (e.g. externally adjust a program value based on ADC port input)

Congratulations to the board designer.

Perfect, nice board, well documented & super communication

For DIP-40 Arduino compatible development board

Shipping was long but looks like Christmas time was really a bad period. Santa Claus was probably too busy ;-) to send something from Norway to France.
What can I say about the board ? It's perfect, easy to use and well documented by its creator. Even for a dummies like I am it works perfectly. In few hours I have been able to play around with 684 and 1284P processors.
And if you are facing problem, or need some additional explanation, just send an email to Hans and you will get a great and clear support.
To conclude I would say that everything is close from perfection ! Thanks Hans.

Fantastic product, easy plug & play!

For DIP-40 Arduino compatible development board

This development board really is fantastic. The layout is very clean and extremely well labeled, It is easy to understand what all the pins do without having to consult documentation. I really like that both male and female headers are available for every I/O, power, and GND pin, as this makes it much easier to connect things with a random assortment of jumper wires. When I first got it I immediately swapped in a 1284p, and it ran without a problem. Arduino IDE under Ubuntu 18.04 with MightyCore sees and programs the board without any extra hassle. I only rated 4 stars on the shipping because it is untracked, and I like to see where my item is.

Thank you for your review! I'm glad you like the board and that you find it useful.

About the shipping, I agree that tracking is much better for everyone. It's nice too see where your package is at all times, and it's saver compared to "regular" mail.
The reason why I don't provide shipping with tracking is simply because it's ridiculously expensive. Personally I don't think $30+ for shipping is fair when the board only cost $35? However I could add it as a shipping option for people who's willing to pay for it.

Shipping was pretty quick and The board works great!

For DIP-40 Arduino compatible development board

This board is going to be the heart of my Raman spectrometer project over at Hackaday, http://hackaday.io/project/18126-3d-printable-raman-spectrometer, it will be running the TCD1304ap CCD chip, which will be the detector. I'm really impressed with the boards expandability for future project developments.

I already replaced the onboard chip (ATmega32,) with the ATmega1284P and the burning the boot loader went off without a hitch, so I was happy about that :)

Great job!
