Introduction

This example demonstrates reading data from I2C based EEPROM devices present in the board. Application reads 20 samples from the EEPROM and exits.

Attention

For AM64xSK, Board ID EEPROM address is 0x51u.

Supported Combinations

Attention

A53 NORTOS support is experimental and is NOT supported by TI.

Parameter	Value
CPU + OS	r5fss0-0 nortos
	a53ss0-0 nortos
	a53ss0-0 freertos
Toolchain	ti-arm-clang
	arm.gnu.aarch64-none
Board	am64x-evm, am64x-sk
Example folder	examples/drivers/i2c/i2c_read

Steps to Run the Example

• When using CCS projects to build, import the CCS project for the required combination and build it using the CCS project menu (see Using SDK with CCS Projects).
• When using makefiles to build, note the required combination and build using make command (see Using SDK with Makefiles)
• Launch a CCS debug session and run the executable, see CCS Launch, Load and Run
