IPG-UI: How to programming to EEPROM

Hi Hirotsugu,

In IPG-UI there should be a tab called "Device Controls". In this tab there is a sub-section called "PROGRAM". Inside this sub-section, there should be an area to "Re-program EEPROM".

You need to click the "Do Action" button to commit the new settings to EEPROM memory as the new defaults.

Hi Hirotsugu,

In IPG-UI you can use the "Write All" button to commit all pending writes to the registers. Then you can program the settings to EEPROM.

In production, you will need a way to write all the registers that require changes. The TPS65218x can handle up to 400kHz I2C speeds so this would be the fastest option.

If you are only talking about IPG-UI then the "Write All" button is your best bet. "Write Group" will write every register under the "Configuration Registers" tab, but since this is the only tab available it is functionally the same a "Write All" so either one will work.

Hi Hirotsugu,

I don't see an issue with the first process. You should be able to make changes to the registers, press "Write All" to send those changes to the PMIC.

Make sure to read back the changed registers after you click "Write All" to make sure the registers have the new values.

Once you confirm that the write operation went through correctly, you can click "Do Action" and those settings should be the new defaults after a power cycle.

Double check that the bit fields you are changing are marked with "E2" *in the datasheet register map.
