Connection in Flash Programm cannot be established about rtd266xflash

Did you change the baud rate in both the GUI tool and the Arduino code (Serial.begin(115200))?

A flashing LED on the Arduino indicates a connection problem. The GUI tool tries to read the error code in btnConnect_Click but this already fails in your case. You should check the connection again. Sometimes the HDMI connector on the display is very sensitive. On one of my boards I had to use a lot of power to plug my HDMI plug into the connector to make it work.

The data you see in response reads overflo when you convert the bytes to ASCII characters. Did you add any output code to the Arduino sketch (Serial.write or Serial.print)? The original code does not print overflo to the serial connection. Any additional output will break the communication between Arduino and the GUI tool

Hello,

thanks for your reply and sorry for the confusion.
Initially the LED was off on the Arduino. After the adjustments to check the sketch the flashing starts.
Now the Arduino is running with the sketch you've provided and the LED is off. Seams to work. But still the flash program ends with error.

The issue still exist in the same method ReadComPort but with a different configuration now.
if (_comPort.BytesToRead > 0) will never be performed because _comPort.BytesToRead is 0. As this is the case the statement will run until the timeout check happens.
This is then also the returning statement return Result.Timeout;

As already mentioned I've no idea and if you would have one would be great. But as it looks like I'm the only one with this issue and if you've also no further idea then the issue can also be closed. I can also live with the ugly screen. Maybe the next screen will work better :)

Best regards
Christian

There either seems to be a problem with the virtual COM port (but it worked with your debug outputs?) or the Arduino is stuck at some place.

I suggest you put some debug output into the Arduino function setup and use the Arduino IDE's serial monitor to display them. Check if it reaches the end of setup and if loop is executed.

I seem to have the same problem, LED not blinking, Serial is working with debug-code in setup() and loop().
I2C Scanner is showing three device IDs. When trying to connect with your programmer I just get "error".

Edit: I just changed the baudrate to 9600 and it connects

Hi,

thanks for the hint. Tried it right now with baud rate 9600 and it connects. Flashing works as well.
Problem solved. Perfekt 👍

Thanks a lot for your help.
Best regards

I have changed them both. When using 115200 baud it didn't work, haven't checked any other baudrate.

[bluesbrother84]

I did the same in GUI and Arduino.

i'm also facing the same issue....
tried 115200 (flashed Arduino) and selected in GUI.... no success
tried 9600 (flashed Arduino) and selected in GUI.... no success

also tried to change the Bit Rate for the port.... no success

disappointing....
