Open jakubsuchybio opened 10 months ago

jakubsuchybio commented 10 months ago

hi, going through https://coral.ai/docs/m2/get-started/#2a-on-linux

point 6. Also verify that the PCIe driver is loaded: ls /dev/apex_0 => ls: cannot access '/dev/apex_0': No such file or directory

uname-r => 4.19.0-25-amd64 (debian 10) lspci -nn | grep 089a => b:00.0 System peripheral [0880]: Device [1ac1:089a]

some debugging i was able to find dmesg

root@debian-frigate2:~# dmesg | grep gasket
[    3.489309] gasket: loading out-of-tree module taints kernel.
[    3.489347] gasket: module verification failed: signature and/or required key missing - tainting kernel
root@debian-frigate2:~# dmesg | grep apex
[    3.492573] apex 0000:0b:00.0: Page table init timed out
[    3.492616] apex 0000:0b:00.0: MSI-X table init timed out
[    3.492814] apex: probe of 0000:0b:00.0 failed with error -110

but i couldnt find anything about these errors

my setup: esxi 6.7 host mini pcie coral tpu via pciem adapter in pcie slot passthrough enabled on that pcie card into the vm in the vm it is listed in lspci as you can see

but that is as far as i was able to get, please help 😅😭
