Hi All
I am trying to operate the PCIe bus board on the IMX6QSABRESD board by referring to i.MX Yocto Project User's Guide (Rev. L5.4.70_2.3.0 — 31 December 2020). However, it does not detect the PCI bus. If it is an old environment, it is detected as (* 2). I thought that the Kernel Config setting was insufficient, so I tried to modify the setting with "bitbake virtual / kernel -c menuconfig", but it was not detected. Please tell me the settings.
An excerpt of the settings at the time of kernel build is posted in (* 3).
Attach the config file.
Best Regards
Hiroaki Okoshi
