We have a custom platform mounting a Xeon D-1715TER . We're trying to launch Slimbootloader+Uboot or Slimbootloader+Netboot to launch our OS via network. Slimbootloader successfully launches Uboot, but Uboot then says "No ethernet found.".
Is this because Uboot doesn't have the device drivers for the E82X integrated Ethernet controller? Is is possible to add them in? I've heard of the "ice" driver but this seems available only on Win/Linux.
Or is the problem due to the Device Tree Source not configuring the PCI correctly? If so what are the correct ranges to configure in the .dts file?
Netboot on the other hand doesn't launch at all, this is being investigated.
On our Brighton City demo board everything works, but that's because the Brighton has an ethernet controller external to the SOC which we don't have on our target board.
Here's a snippet of the Uboot output on our target:
U-Boot 2025.07-rc2-00026-ga3e09b24ffd4-dirty (May 22 2025 - 09:00:10 +0200)
CPU: x86_64, vendor Intel, device 606c1h
DRAM: 18 GiB
Core: 11 devices, 7 uclasses, devicetree: embed
Warning: Device tree includes old 'u-boot,dm-' tags: please fix by 2023.07!
MMC: pci_mmc: 0
Loading Environment from nowhere... OK
Net: No ethernet found.
Thanks.
