I2C detect sample - no UART output

[DmRu_4683001]

Sample code is a copy of https://iotexpert.com/2019/08/05/i2c-detect-with-psoc-6/

The Library Manager tells something strange when attempting to add retarget-io library:

WARNING: Uncommitted/Untracked files detected in C:/Users/user/mtw/ProbeI2C/libs/TARGET_CY8CKIT-062-WIFI-BT.

  Save your work in source control before updating this library.

The code compiles and uploads ok but no serial info displayed, same in BMI160 with UART doesn't work on CY8C6247BZI-D54 as described in "PSoC 6 101: Lesson 3-5a Basic Moti...

WICED UART projects work ok.

Hi DmRu_4683001​,

MTB 2.x uses the retarget-io library to enable printf with the SCB block of PSoC 6. Please make sure you have followed these steps to retarget the standard input/output (STDIO) messages to a UART port.

1. Use Library manager to add retarget-io MW to your project.

2. Add #include "cy_retarget_io.h"

3.Call cy_retarget_io_init(CYBSP_DEBUG_UART_TX, CYBSP_DEBUG_UART_RX, CY_RETARGET_IO_BAUDRATE);CYBSP_DEBUG_UART_TX and CYBSP_DEBUG_UART_RX pins are defined in the BSP and CY_RETARGET_IO_BAUDRATE is set to 115200. You can use a different baud rate if you prefer.

4. Start printing using printf()

If the above steps doesn't work. Please share your project to us so that we can debug the issue at our end.

Regads,
