Hi,
I try to boot from a network card in the PCIe slot but somehow U-Boot does not recognize it.
U-Boot 2016.07-g0ce7ca2 (Jul 20 2017 - 00:37:03 -0700)
TEGRA210
Model: NVIDIA P2371-2180
Board: NVIDIA P2371-2180
DRAM: 4 GiB
MC: Tegra SD/MMC: 0, Tegra SD/MMC: 1
*** Warning - bad CRC, using default environment
In: serial
Out: serial
Err: serial
Net: No ethernet found.
Hit any key to stop autoboot: 0

From the debug output it looks like it can’t see the PCI regions at all.
From other users in this forum I can see that U-Boot seems to detect the PCI regions and print them as debug info:
tegra-pcie: PCI regions:
tegra-pcie: I/O: 0x0000000012000000-0x0000000012010000
tegra-pcie: non-prefetchable memory: 0x0000000013000000-0x0000000020000000

tegra-pcie: 4x1, 1x1 configuration

tegra-pcie: link 0 down, retrying
tegra-pcie: link 0 down, retrying
tegra-pcie: link 0 down, ignoring
tegra-pcie: probing port 1, using 1 lanes
tegra-pcie: link 1 down, retrying
tegra-pcie: link 1 down, retrying
tegra-pcie: link 1 down, retrying
tegra-pcie: link 1 down, ignoring
Any idea how I to make it work ?!
Thanks,
