Backplane hardware design

Hello there!
Problem description: As needed, I added 12V to 5V power supply on the B01 backplane. After welding, I found that the 5V power supply of the USB interface did not output. After checking the DSP1_PWR pin of the RTS5411S-GRT chip to control the EN pin of the TPS259530DSG chip, the DSP1_PWR pin always outputs a low level in the working state, which is in accordance with the relevant description in the chip manual. When the B01 development board purchased from the official website runs, the DSP1_PWR pin outputs a high level.
I would like to ask: What is the reason for this and how to solve it?

Hi,

Which board or GPU is it and what is the goal of the project?

Thanks
