Jetson Xavier PCIe reset de-assert two times on PCIE0&PCIE1 during system power-up

Hi~

We used the same image on Xavier A02 & A03 module to measure PCIe power-up sequence, but we got a different result as blew:

Xavier A02 module(SD card sku) → PCIe RST & CLK de-assertion one time

Xavier A03 module(eMMC sku) → PCIe RST & CLK de-assertion two times

Could you explain what difference between A02 & A03 modules??
