PIC, AVR, and Arduino programming in Haiku

Off-Topic

That seems very very strange… perhaps the wrong oscillator setting is being used?

24

Dunno. I used the same makefile and fuse settings as I did from Debian 10. Except the avr build tools in Haiku did not recognize
avr-size --format=avr

That’s the setting I used in Linux. The haiku version gave me a choice of SysV or BSD style. I chose BSD and stopped after I had the success of seeing Haiku blinkenlight auf das protoboard. It was late and I didn’t feel like further pursuits at the time.

Here is what I changed from the makefile that worked in Linux to the one that barely worked in Haiku.

I’ll try some other settings to see what it does. IIRC, I did not have to make this change to the Makefile in my previous attempts. But previous attempts were totally fruitless.

Apparently avr-size in Haiku doesn’t recognize sysv formatting either.

avr-size is used to print some information about the size of your code. You could remove this line entirely and the makefile would still work.

The problem you had was with writing the fuses, anyway, not with flashing the program itself. So the .hex file isn’t even used for that step.

Probably there is still something wrong with our libusb port and it will somehow not manage to write the fuse data. I had that happen a few times as well here, but usually I got it to work after several retries, or I just flashed the fuses once on another system and then did not need to rewrite them.
