TPS650330-Q1: no output voltage issue

Tool/software:

Hi, Support Team

our client first time use TPS65033000-Q1, input Vin=12V but no output voltage(+3V3/+1V8/+1V2/V1P8)

how to confirm IC is work?

 schematic as below chart:

also we find TPS6503xx-Q1 Camera PMIC Programming Guide:

about 2.3 Default Register Settings
The TPS65033000-Q1 is tailored to program in mass production. The following features help enable this:
• Only the VSYS/VSYS_S/PVIN_B1 input voltage and I2C pull-up voltage are required to communicate with
the device through I2C.
• The SEQ pin must be logic HIGH to enable all regulators.
• The GPIO pin must be logic HIGH to enable Buck3 and the LDO.
This definition enables various paths to production programming as discussed in detail in the following sections.
1. Production line programming
2. Serializer-Deserializer (SerDes) back-channel programming
For a high level overview of the TPS65033000-Q1 default voltage, sequence, and other settings, see the
Camera PMIC Spin Selection Guide.

its mean SEQ pin and GPIO pin default should be pull high and than start up output voltage?

if yes, how to Production line programming  do not use SEQ and GPIO pin?

if any suggestion, Please advise me.

Thanks,

Best regards,

Lawrence
