Bug #350
openI225 PCIe device not detected on Harcuvar
0%
Description
Hello,
I'm working on an Harcuvar devboard (serial PWHA61500083) flashed with coreboot master branch (aade40c3).
I plugged a PCI QNAP 2G1T I225 PCI/Ethernet device on the Harcuvar PCIe x8 slot.
The device is not visible by coreboot and not listed in the lspci/dmesg output of
the mainline Archlinux distribution I'm using.
On an other machine, the PCI QNAP 2G1T I225 is correctly detected and the corresponding "igc" driver is loaded.
I plugged a completely different PCIe device (serial converter) on the same slot. It is detected correctly and
visible by Linux:
[DEBUG] PCI: 00:09.0 scanning...
[DEBUG] PCI: pci_scan_bus for bus 02
[DEBUG] PCI: 02:00.0 [1c00/3253] enabled
[INFO ] Enabling Common Clock Configuration
[INFO ] PCIe: Max_Payload_Size adjusted to 256
[DEBUG] PCI: 02:00.0: No LTR support
[DEBUG] scan_bus: bus PCI: 00:09.0 finished in 22 msecs
whereas for the I225, nothing appears on the same bus:
[DEBUG] PCI: 00:09.0 scanning...
[DEBUG] PCI: pci_scan_bus for bus 02
[DEBUG] scan_bus: bus PCI: 00:09.0 finished in 4 msecs
any idea what could go wrong here? A boot log with the I225 device plugged is attached.
Thanks,
Mathieu
