Basic Assembly and Setup

I used this guides https://docs.petoi.com/api/raspberry-pi-serial-port-as-an-interface

and when try to run ardSerial.py get next

>> python3 ardSerial.py ksit
2022-07-10 00:59:24,082 __main__ - INFO - port[0] is /dev/ttyAMA0 
2022-07-10 00:59:24,082 __main__ - INFO - port[1] is /dev/ttyS0 
* Port ttyAMA0 cannot be opened!

* Port ttyS0 is not connected to a Petoi device!
No port found!
You can type 'quit' or 'q' to exit.
2022-07-10 00:59:28,097 __main__ - INFO - finish!

[17.07.2022] UPD: when upload new version OpenCat got error "sketch to big" for board ATmega328P (5V, 20 MHz) NyBoard V0_1

for Arduino uno compiled successful but I can't upload program to Nubble cat

I checked this post https://www.petoi.camp/forum/basic-assembly-and-setup/opencat-sketch-too-big-solved

installed IRremote 2.6.1v

in IRremote I disable RC5 RC6 params

Operation System is macOS Monterey(intel Core i7)

[24.07.2022] UPD I founded this code and comment it

and this issue is resolved 🎉

but I can't send command from PI getting the same error
