I try to rescan my Pcie devices after booting but it doesn't work.
The command used for rescan is : "echo 1 > /sys/bus/pci/rescan"
This command is very very fast and gives no output. "Lspci" gives nothing. If i reboot my IMX8M card, i can see my pcie devices.
Have you got an idea about the problem ?
(I use yocto with BSP and kernel 4.14.78)
