Hello!

I see example "cyfxuartlpregmode"

I could not make it workable

determine the speed 115200, transfer to UART, I expected answer, but it absent.

What is it?

Or tell me how to correctly make UART a loop back (echo)

I'm using WIN7

Many stanks

Change the io_cfg.lppMode   = CY_U3P_IO_MATRIX_LPP_UART_ONLY; in CyU3PDeviceConfigureIOMatrix configuration to io_cfg.lppMode   = CY_U3P_IO_MATRIX_LPP_DEFAULT; and build the firmware then check.

This is needed for every firmware that is being tested on CX3 Kit.
