Out of ideas to get atmega4809 to work
Thanks, js. I suspected lifting the UPDI pin on that xplained board would be one way. I have fair soldering skills (enough to solder the 4809 into a breakout) but it can be a...

Thanks, pgillard. Atmel gave me a phone number to call for my submitted case; perhaps they will tell me they reproduced the problem, as they apparently told you. I think it...

As you can see from a post a couple before yours, I did submit a case to Atmel.

Thank you for sharing your wisdom, clawson! I myself have found the STK600, well, not in such a different class than the STK500. I used the STK500 for years, and it was fine...

Ok, submitted case 00307099 to Microchip, with subject "AS7 + STK600 cannot yield running ATMEGA4809". (I accidentally left the "include ..tpc.h.. in there, but hopefully they...

Hmm, it appears as though it is difficult to submit as case to Atmel without having a support contact. Does anyone have an email address or something to submit a bug report to...

I put an atmega88 I had lying around on a breadboard and built El Tangas' jtag2updi code for it, and flashed that code, and made use of his avrdude.conf file in order to use...

Thank you for all the help, folks.   I soldered my second 4809 that I was trying in that clamshell onto a 48p breakout, and . . . it shows the same behavior as when it was in...

Thanks js. Re the clamshell, the contacts are a bit springy; when the lids is closed it presses the pins into the contacts. Still, could use up one of my two 4809s soldering it to...

Good question; I am using a Yamaichi clamshell as in https://www.mouser.com/ProductDe.... It looks pretty solid in there . . . this clamshell has worked for various ARM chips...

pgillard, can you elaborate on this? Other than trying out avrdude with his avrdude.conf file that has jtag2updi in it, I don't know what specific steps to try (don't know "...

js, you said with my code the portb output was "high". Do you have a scope? Are the pins on your board for portb actually toggling at high speed with my code on your board? I like...
