So I get two kayla boards and two GT640 cards as suggested by NVIDIA on https://developer.nvidia.com/content/kayla-platform. Sometimes if I was lucky enough, one of the card works perfectly. But in most time it turns out none of the card works on either kayla board. Dmesg gives me something like this:
[ 13.551232] NVRM: failed to copy vbios to system memory.
[ 13.552338] NVRM: RmInitAdapter failed! (0x30:0xffffffff:711)
[ 13.552364] NVRM: rm_init_adapter(0) failed
I am booting from the on board eMMC and didn’t change the factory default rootfs too much. My change includes:
- Install PAPI/TAU/PDT under /opt and update ld.so.conf.
Those are tools/libs for performance analysis. See links below:
- Kayla comes with nVidia driver v313.24, but I have also installed/tried v325.15 and v319.32 (of cause I uninstalled old driver before install the other one).
I tried to mount those two GT640 cards on my PC (x86_64, Debian SID) and it works like a charm with NVIDIA driver, so I guess this should be a software / configuration issue.
What should I do next to debug this issue? Also please kindly let me know if this is not the right forum to post such question.
