If we look at the Nano Every pin-out from MegaCoreX, it…

My board with the ATmega4808 generates correct output in the serial monitor at 16 MHz. Garbage occurs at 20 MHz.
I tested this at 38400 bps. There might be an error in the calculation of baud_setting…

Strange that I am seeing issues with EEPROM write for the bigboot optiboot for the ATmega328P with `-c urclock`. `-c arduino` is okay.
This is with a new Nano clone with ATmega328P and FT232RL. Str…

### Report: Incorrect SerialUPDI control of AVR64EA32
This is a known bug as of commit 481a91d.
1. You are trying to read the "Chip Silicon Revision" register without checking the status of the …

## libusb0.dll missing
At Embeetle IDE, we provide one of your Windows releases on our download server. One of our users experienced the following error on Windows 10 when trying to run the executa…

AVRDUE only invokes the programmer's *_paged_load() and *_paged_write() when the memory page size exceeds 1. Compact bootloaders (think optiboot et al) typically only ever implement paged memory acces…

~~I'm not sure if this is a bug in the Xplainedmini_updi firmware, or has something to do with Avrdude.~~
EDIT: It appears that all JTAG3 based UPDI programmers are affected.
Unlike other UPDI pro…

Unlike other AVRs, the internal oscillator in the ATtiny13/A runs at 9.6 MHz and is dividable down to 4.8 MHz, 1.2MHz, and 600kHz.
It would be great if these existed pre-compiled bootloaders for thes…

(Probably) related to #1090.
I'm able to upload programs to an ATtiny1616 using optiboot (-c arduino) with Avrdude 6.0 and 7.0, but not the upstream version.
I've tracked down the issue to commit …

This is something I'd wanted to implement for a while, but haven't really figured out how without completely rewriting the existing implementation. The main problem is that the current implementation …
