Could you share your project?
It is not related to any project, the problem is trying to communicate over I2C using the Bridge Control Panel. When connected to a sensor on the CY8CKIT-062-WIFI-BT board a "list" command properly returns the sensor address's. However when i connect the sensor exactly the same way(SCL @ 6.0, SDA @ 6.1) to the CY8PROTO-062-4343W board it does not work, or see the sensor.....
I don't have a I2C sensor, so i programmed an EZI2C demo project into P6 devices to do the test use BCP, i can read I2C address by using both DVKs
My test ModusToolsBox project and final elf file is attached(CY8CPROTO-062-4343W). If you still cannot find the i2c address use BCP, please check the resistor R15, R16 is exist on your CY8CPROTO-062-4343W board or not, they are pulled up resistors.
