I’m on Montery (12.3.1) and I have a project that I need to modify. It’s worked fine previously, and I think even on the Mac although I had to load an unsigned “kext” to get things moving.
I usually work on Linux or Windows (at a pinch) but I’m stuck with the Mac for now.
This is what I THINK used to work.
upload_protocol = atmelice_isp upload_port = /dev/cu.usbserial-14130 upload_flags = -C $PROJECT_PACKAGES_DIR/tool-avrdude/avrdude.conf -p $BOARD_MCU -P $UPLOAD_PORT -c atmelice_isp
But now AVRDude is
bitching complaining about the USB port. I think someone had a fix for this but (as is typical) that seems to have gone missing in the mess of the Internet and vagaries of search engines.
avrdude: jtag3_open_common(): JTAGICE3/EDBG port names must start with "usb"
I’ve found the serial upload utterly hopeless on these cheap Chinese clones but right now it’s all I have and the only way I can make them work (at all) is to use an ICE programmer.
I’m migrating to ESP32 an other boards (like the Pi Pico and Teensy) but I need this thing uploaded to a Uno because it is deigned for a specific LCD HAT.
