Hi All, I am testing with ‘AMD Radeon Graphics Card’ with two different vendors computer-on-modules. This graphics card works fine with “RadiSys Corporation CEGM45 – COM” and “Phoenix Technologies Ltd BIOS” , but fails with “BT2 Adlink COM Express Type 2 module” and “American Megatrends Inc – BIOS”. Lspci does not even show the graphics card. Complete kernel log is attached. Any idea, what might be the reason for not detecting the PCIe graphics card? Is there any BIOS settings related to PCIe needs to be checked? lspci output: 00:00.0 Host bridge: Intel Corporation ValleyView SSA-CUnit (rev 11) 00:02.0 VGA compatible controller: Intel Corporation ValleyView Gen7 (rev 11) 00:13.0 SATA controller: Intel Corporation ValleyView 6-Port SATA AHCI Controller (rev 11) 00:14.0 USB controller: Intel Corporation ValleyView USB xHCI Host Controller (rev 11) 00:17.0 SD Host controller: Intel Corporation ValleyView MIPI-HSI Controller (rev 11) 00:1a.0 Encryption controller: Intel Corporation ValleyView SEC (rev 11) 00:1b.0 Audio device: Intel Corporation ValleyView High Definition Audio Controller (rev 11) 00:1c.0 PCI bridge: Intel Corporation ValleyView PCI Express Root Port (rev 11) 00:1c.1 PCI bridge: Intel Corporation ValleyView PCI Express Root Port (rev 11) 00:1c.3 PCI bridge: Intel Corporation ValleyView PCI Express Root Port (rev 11) 00:1d.0 USB controller: Intel Corporation ValleyView USB Enhanced Host Controller (rev 11) 00:1f.0 ISA bridge: Intel Corporation ValleyView Power Control Unit (rev 11) 00:1f.3 SMBus: Intel Corporation ValleyView SMBus Controller (rev 11) 03:00.0 Ethernet controller: Intel Corporation I210 Gigabit Network Connection (rev 03) -- Thanks, Sekhar
