AM623: In boot the GPIO output issue

Part Number: AM623

Tool/software:

Hi

I have a question on E2E (see the following link) about the PMIC output. The main issue is that the AM623 output to the PMIC TPS6521904 causes LDO1 to switch to 1.8V. The AM623's GPIO0_31 is not pulled to "low", but to a strange half-level position, making the LDO1 output voltage become about 2.5V.

Another person asked us to open another topic to ask about this part. Please help me confirm what might be the problem here.

Thanks.
