Cannot upload sketch - not in sync

I have been uploading different sketches to the NyBoard v1.1 so I can use different I2C devices with it. At one point, I started getting an error and it does not allow me to upload any new sketches, always with the same type of error. Below I am simply trying to upload a blank sketch:

Sketch uses 3852 bytes (11%) of program storage space. Maximum is 32256 bytes.
Global variables use 578 bytes (28%) of dynamic memory, leaving 1470 bytes for local variables. Maximum is 2048 bytes.

Failed uploading: uploading error: exit status 1

Any ideas?

Edit:

There is data coming from the serial console from a previous sketch, so the ATMega is still working:

09:47:57.058 -> Init servos: k 
09:47:57.192 -> Init IMU 
09:47:57.678 -> Init servos: k 
09:47:57.810 -> Init IMU 
09:47:58.309 -> Init servos: k 
09:47:58.417 -> Init IMU 
09:47:58.960 -> Init servos: k

What type of warranty does the mainboard have? 😪

Thanks for the offer. I have actually gone another route with the Bittle and am more than happy to share my research with you. I am in the process of replacing the entire NyBoard with a Pi Pico W, as it is significantly more powerful, has 16 PWM channels, built-in WiFi and other nifty features.

I will start another thread on it. I have some challenges that I am dealing with and would love some help (driving the servos with 3.3V logic, translating the kinematics from what's in the code to actual servo angles, etc.).

You may refer to the OpenCatEsp32 code, which uses a more powerful chip with less confusing memory management.

Thanks for bringing it to my attention! Yes, the BiBoard looks great. Almost same price as NyBoard. Save me all the trouble of figuring out the Pico+bittle!

"programmer is not responding" is often happened when there is no correct serial port found. If you operate in Windows, please check the serial port is found correctly and the port set in the Arduino IDE as follows before upload the sketch.

Port found just fine. Arduino won't even properly attempt an upload if port not found. Attempted on two different Windows laptops.

1. Make sure you have selected the right board and port correct board under Tools > Board (Arduino Uno) and Tools > Port (correct port).

2. Do a loopback test can be performed, which will rule out problems with the serial chip.

Connect a jumper cable from RESET to GND.

Connect a jumper cable from Digital 0 (RX) to Digital 1 (TX). as follows:

If the loopback test passes, or if you can’t do a loopback test, reprogramming the bootloader may resolve the issue.

I just did a successful loopback test but a failed bootloader reprogram attempt, see error I posted to Li's thread. Thanks.

Hi, could you take a short video to show the LEDs on the green uploader during the uploading process? Is the yellow LED consistently lighting up?

For the details about Step1: Open the ArduinoISP firmware (in Examples) to your Arduino board:

Note: Please do not connect to USB or power supply the boards while you set up the connections and wires. We also suggest that you first program the Arduino used as ISP programmer before you proceed with the wiring to the target board.

Load the sketch

The Arduino that you will use as programmer needs a specific sketch. You find it under Examples > 11. ArduinoISP > ArduinoISP .

I was able to flash the bootloader!

After doing so, I uploaded the stock OpenCat sketch successfully. However, it does not appear to be working the same.

Here are the messages I receive when turning it on:

12:14:19.936 -> k 
12:14:20.058 ->  
12:14:20.058 -> * Start * 
12:14:20.058 -> N230305 
12:14:20.058 -> Bittle 
12:14:20.609 -> IMU 
12:14:21.108 -> Servo:25.00 
12:14:21.148 -> Skill

It does a beep, then stops there. It does not respond to anything, or even buzz due to no battery. Thoughts?

Please use Arduino IDE, upload the sketch as follows:

1. Configure the robot type and board version

2. Setup the configuration mode

3. Plug the USB uploader into your computer

4. Plug the USB uploader into the NyBoardv

5. Upload the configuration mode sketch

6. Open the serial monitor

7. Reset joint offsets (Input ‘n’ and hit Enter)

8. IMU (Inertial Measurement Unit) calibration (Input ‘Y’ and hit Enter)

9. Calibrate the servo controller chip PCA9685 (Do nothing, this step CAN be skipped)

10. Upload the major functionalities sketch

11. The module macro in the code

The details please refer to the Petoi Doc Center:

Sometimes it does start the board correctly, sometimes not. When it does work, this is the serial output:

There are two special cases in the design:

If the battery is not turned on, it will beep the low power melody.
If the robot is tilted when booting up, it will enter the calibration posture.
