Hi,

I bought a new CY8CKIT049-42xx. I just started writing code. I have read and implemented CY8CKIT-049-4xxx PSoC® 4 Prototyping Kit Guide to program. But I get a mistake. I have read the forums but I have not found a solution.

Error: Communication port reported error 'Unable to read data from the target device'.

Can you help me?

Hi user_4595331​,

Can you let me know how you are programming the device?

Please try the following debug steps -

1. Connect the Kit to your PC.

2. Open PSoC Programmer and see if the device gets connected.

3. If the device gets connected, click on Erase All Flash icon.

4. Program a hex file using the PSoC Programmer and check if you are able to program the device.

Please share the screenshot of the error in PSoC Programmer if you are unable to program the device.

Thanks and Regards,
