1 Purpose and Scope

This application note details the TPS2576x-Q1/TPS2577x-Q1 firmware update process. The TPS2576x-Q1/TPS2577x-Q1 firmware, which includes the boot and application code, is stored in the ROM to execute device functionality. The device can then accept patch bundles (containing code patch and application configuration) from an external host or EEPROM over the I2C bus and is stored in the SRAM. The patch bundles can be generated using the TPS2576x-Q1/TPS2577x-Q1 application customization tool (TPS257XX-Q1-GUI on TI's website). To learn more about the GUI, see the TPS257XX-Q1-GUI Configuration Guide.
