Can't load program / unable to run
I have a ATtiny84a. Everything worked until I tried to upload new code via debugwire:
Unconnected. > device tty.usbserial-AH06TDUZ
Connected to ATtiny84 on /dev/tty.usbserial10 at 30949 baud.

Questions:
- What should I do next? quit and restart doesn't seem to work. The program is not running (or sth is running but not what should)
- Why is the application telling it's device dev/tty.usbserial10? There's no such device, only tty.usbserial-AH06TDUZ
- If I add baudrate, eg 9600 or any other value not around 30949 baud the device is not found at all, how come?
- I also tried with a CH340, but no device is found even /dev/tty.wchusbserial1420 is there :-(
Maybe someone can help me getting things going on?
Just a short update: I was able to update new code by switching to ISP mode with the command "qi" and updating fuses or software via ISP connector.
THIS APPEARS TO BE WRONG: Somehow the *.elf file was broken. I 1st checked to generate a correct elf file until uploading it via isp works. Now that file also can be uploaded with debugwire.
It seemed to work, because I uploaded the same elf. And then no error is thrown. So seems that I can't upload a file via debugwire. No matter what I do (I even changed to a 1N4148 to be sure), I get some errors. This seems to somehow mess up the memory, as afterwards nothing works anymore. No reset, no go, no nothing...
