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


      I has CY8CKIT-049, in this I completely uploaded UART Boolloader. Also many Project on Capsens and UART.


      After that I started to make my own KIT of PSoC, In which i used CY8C4245AXI-483 Chip which i bought from element14.


      However after completing soldering I connect that controller of PCB to USB to Serial Bridge (CY7C65211-24LTXI) for upload code to controller via UART. After that I start to upload code by Bootloader Host. But I got an error "Unable to read data from target device."


      So, I checked all the connection of UART, Power Supply first. Then I checked setting of COM port as well as UART Communication parameter like Baud-rate(115200), Data-Bit(8 bit), Stop-Bit(1), Parity(None). But It's all correct, and I also checked power supply. I am giving 5V DC to Controller.


      I attached PDF file which I follow to make my KIT(For follow circuit diagram as well as programming).


      Is fresh chip does not contain inbuilt UART boot-loader ? If yes then please give me steps for upload boot-loader.


      Please provide suggested solution for upload UART Boot-loader to fresh PSoC chip.


      Thank you,
