Hello. nVIDIA staff
TX 1 may not start depending on the power supply source, which is troubling.
It occurred during product start-up test.
For the power supply system 1, start up 100%.
In the case of the power supply system 2, only about 50% is normally activated.
· It is a custom board.
· It adopts Auto-Power_ON mode.
· The power supply of the carrier board is 100% normal.
· The power supply of the carrier board is on, and RESET is negated.
· There is no log output on UART 0.
Is there something the TX 1 does not move while the power management IC is running?
What is the cause?
Please let me know if there are regulations that I must not protect.
