Flash error: avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00

Hello, I am trying to flash my Arduino Nano and I can't figure out where the error is coming from. The error is avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00 This prevents me from flashing at all.

Thanks for reading!

Are you able to flash this Arduino in other ways, eg from Arduino IDE, or using avrdude on the command line?

I'm assuming you're connected via the Micro USB port— are you certain you have permissions set up correctly? See: https://www.arduino.cc/en/Guide/Linux#toc6

Try to press the RESET button at the beginning of the upload process.

Hey, I've been running into this issue (and a similar one) and was hoping to see if there has been any progress on this, here's some info about what I'm doing:

• I'm running the rosserial-arduino cmake tutorial NOTE: this is apart of a larger package, so my rospackage name is arduino-ros and not helloworld as indicated in the tutorial...I have made sureto update everything as necesarry
• I have been able to run and deploy this via the arduino IDE
• Yes I tried looking through the link in @mikepurvis' comment
• I have tried deploying to an Arduino Uno follwing the instructions in that tutorial, and I get the following error when attepmpting to run make arduino-ros_firmware_hello-upload :

avrdude done. Thank you.

Any help or pointers would be appreciated--thanks!

**EDIT** 
- I have been pressing the reset button at the beginning of the upload process, no change
- I am running ros melodic (not sure if that matters, but I figured having the system might be important)

Update: After digging WAY to deep for nothing, I found out that you need to set SERIAL in the cmake function generate_arduino_firmware, so the full function for me is:

generate_arduino_firmware(hello
  SRCS chatter.cpp ${ROS_LIB_DIR}/time.cpp
  BOARD uno
  PORT /dev/ttyS4
  SERIAL picocom /dev/ttyS4
)

It uploads correctly for me and runs by adding that line.

Would it be possible to update the tutorial? Not sure if this is the right place for that. -T
