C6678 PCIe note getting detected on Linux PC i5

Other Parts Discussed in Thread: TMDXEVMPCI

Hi,

I have installed C6678LE EVM on Intel core i3 PC running Ubuntu 12.04. When I boot my PC, the PC does not detect the PCIe card. Even the ehternet of PC is not getting enabled. I tried to program the IBL as said in wiki page (http://processors.wiki.ti.com/index.php/BIOS_MCSDK_2.0_User_Guide#IBL). But still I see the same issue. I am using AMC to PCIe adapter (TMDXEVMPCI)

If I connect the same card to an Core 2 Duo machine, the PC is able to detect the PCIe card.

Is there any limitation on the board with respect to Linux OS and motherboard or PC processor?

Regards,

Sri.

    Hello Sri,

    If after programming IBL and pick correct jumper settings, the cards work fine on one PC but no the other, then we can check the pc in your failed case. If you plug in another PCIe card, was it working fine? Can you also trype in beow command in Linux to get slot properties:

    sudo dmidecode --type 9

    Does your BIOS offer a slow boot option?

    If above doesn't work, then we need to connect code composer studio to debug it. One idea is to get PC value and dump of PCIe registers for both good and bad cases so that can be compared to find clues.

    regards,
