TPS65987D: Please let me know how to re-patch

Part Number: TPS65987D

Load the patch without flash using I2C.

I use CustomizationTool to create a patch.

PTCs-> PTCd-> PTCc

I confirmed that the Mode register returned 'APP '.

After this, how do you re-patch with different settings?

    If the host intends to load a different patch bundle (either application configuration and/or device patch) after the device has already transitioned to the 'Application' mode (either by loading the default configuration or after a previous patch download sequence), the patch download sequence detailed in www.ti.com/.../slva972a.pdf shall be preceded by a 'PTCr' (Patch Reset) and succeeded by a 'Gaid' (Warm Restart) 4CC command. Note that 'Gaid' shall not be executed if the device is operating in dead-battery mode. The host shall wait till VIN_3V3 becomes available to the device, and then clear the dead-battery flag for the new configuration to take effect.
