05:02 PM damjan: hi all, I have one of those xplained mini board with attiny817, as far as I understood they have a bug in the bootloader so it fails to program with avrdude (latest build). anyone knows how to update the bootloader on *Linux*
05:07 PM damjan: this is the board https://microchipdeveloper.com/boards:attiny817
05:10 PM LeoNerd: I just write them using plain UPDI without an onboard bootloader or weird things
05:11 PM LeoNerd: Any ol' UART cable (e.g. I sell some but really you can just use any FTDI/Silabs/Prolific/whatever) and pyupdi or Device::AVR::UPDI
05:28 PM djph: the xplained boards use medbg via that 32u4, iirc ...
05:37 PM damjan: yeah
05:41 PM djph: you trashed medbg or some such then? ouch:(
05:44 PM damjan: djph: they have shipped them with semi working medbg
05:45 PM damjan: https://lists.nongnu.org/archive/html/avrdude-dev/2018-01/msg00007.html
06:14 PM Smidge204: So you need to load the new firmware into the 32u4 then?
06:19 PM Smidge204: http://ww1.microchip.com/downloads/en/DeviceDoc/50002657A.pdf Page 10, section 3.3 "mEDBG Firmware Upgrade and Manual Bootloader Entry"
06:27 PM damjan: yes
06:27 PM damjan: the link is dead though
