Can't Upload Sketch - Resource Busy

ndreisg commented 5 years ago

Hi!

When I try to upload a sketch to the Arduino Nano with my Macbook I get the following error:

avrdude: ser_open(): can't open device "/dev/cu.usbserial-1410": Resource busy

I found some tips on stackoverflow (create /var/lock directory, check for other processes blocking the port with lsof, disable csrutil, use newer driver version 1.5) but unfortunately none of them could solve my problem.

I also tried with a Debian system, but that didn't work either.

I tried to use another USB cable to make sure the delivered cable isn't broken, but that also din't help.

Is there something else I can try, or did I miss something?

Regards Alex

@ndreisg Any luck with the issue?

ndreisg commented 5 years ago

Yes. I switched processor to "ATmega328P (Old Bootloader)" in Arduino IDE.

IDE version bigger than 1.8.5 need use old bootloader

emakefun / emakefun-nano-kit
