I'm having issues when trying to program an ATtiny424 using a high-voltage (HV) programmer. Programming and setting fuses work perfectly without the HV programmer, but I want to experiment with some f…

Great range of HV UPDI programmers. Only thing is that you use the CH330N which seems to be discontinued.
Is there a replacement chip?
Will you be updating the designs for a new chip?
Better yet,…

For those of us that don't want to modify it, but "just drop it in and go", it would be nice to have something that is already known to work with a standalone programmer.
I can export a hex file fr…

Hi Folks,
Can anyone help me with following error screen shots?
Setup TTL to uart converter: CH340G
TX connected to RX with 4.7K connected to UPDI (PIN6)
VCC of UART & ATT402 shorted to 5V

Well, I have no idea where else to go. I bought a brand new ATTiny from Mouser and it seemed to come locked. So I tried to unlock it by erasing it (`-e` or `-e -F`), which just gave me the error here:…

The page:
https://github.com/SpenceKonde/AVR-Guidance/blob/master/UPDI/jtag2updi.md
is a bit daunting for someone just wanting to get UPDI to work with DxCore or megaTinyCore.
It's great to h…

Trying to upload code to the Adafruit Seesaw ATTINY1616, without success.
Arduino IDE compiler gives me the "UPDI init failed: Can't read CS register" error.
What have I tried so far:
Different p…

It's written frankly, so even if it's automatically translated into English, it might not come across correctly.

Good day!
I mean the MCU having lock byte set. At least when using avrdude.
The reason is code of JTAG2::enter_progmode(). Briefly: this code is not working completely if the MCU is in "locked"…
