TPS6593-Q1: Not getting power on VOUT_LDO2 (pin no 11)

Part Number: TPS6593-Q1

Tool/software:

Hello Ti,
I am using   TPS65931211RWERQ1 with AM62A34ASMSIAMBRQ1
In some of the boards i am not getting 1.8V on  VOUT_LDO2. But in most of the boards I am getting 1.8V. The VPP_EN is coming from the IO_exp as similar to the EVM ( PROC135A) design.

please find the attached snap of the schematic


Best regards

    Hello Abhineet,

    In TPS65931211RWERQ1  NVM, the LDO2 is configured in such a way that it gets enabled in Active state whenever there is detection of rising edge on GPIO9 after NRSTOUT has been released. So have you checked that are you doing that correctly as expected?
