Can't program ATTiny3216 under SpenceKonde/megaTinyCore #4

Closed tgtakaoka closed 4 years ago

tgtakaoka commented 4 years ago

As noted on Usage section of MCUdude/microUPDI README.md, setting Arduino IDE's programmer to Onboard Atmel mEDBG (xplain_mini) (megaTinyCore) doesn't upload a sketch to bare ATTiny3216.

I think -cjtag2updi option of avrdude should be -cxplainedmini_updi. Should I modify avrdude.conf of megaTinyCore to include xplainedmini_updi. Am I right?

Ah, I should report this to SpenceKonde/megaTinyCore project, not here.

You're right, there is something wrong with the way megaTinyCore handle programmers.

Thanks for your contributions to the MegaCoreX and megaTinyCore projects! Your time and knowledge are highly valuable 😊
