I have made a custom carrier board for the Jetson AGX Xavier.This is my hardware design.
When the board is powered up, it can’t find pcie device(Tsi721) and there is some pcie bus errors.
Q1:Is PEX_CLK5_P/N HCSL or LVDS level?
Q2:Whether the reset time（PEX_L5_RST_N） can be modified?
Q3:When the pcie device link down, how to let pcie device link again?
Have you checked the NVIDIA Jetson Linux Driver Package Software Features : Jetson Module Adaptation and Bring-Up | NVIDIA Docs to bring up your AGX Xavier module with PCIE device?
I changed the Jetson Linux Driver Software, it’s ok now.
tegra-l4t-r32.7.1 is not ok.
tegra-l4t-r32.5.2 is ok.
