Hello,
I am using Yocto to build Linux image to run on IMX8M-MINI based DART-MX8M-MINI SOC ,on VAR-DT8M Board.
I booted the board with the fsl-image-gui image copied on SD card, and from log I doubt it is bringing up the PCIe bus.
The build procedure I am following the doc setup guide , and I didn't apply any changes on the Yocto project.
I haven't connected and mini PCIe device but wanted to know from the boot log i received if that is what is expected and if the bus is enabled, the CONFIG parameters for PCI in my dts file seems to be enabled.The boot log I received is:
