Hi MTK:
As the title, the ubuntu system on Genio 1200 can not detect the PCIe device (APU). But the device can be detected by ROCK 5B EVB. For this issue, can you give some suggestions about it? Or deliver the correspond PIC? Thanks a lot.
The details as follows:
HW platform:
Genio 1200 EVK
Image:
Ubuntu Desktop 22.04 LTS
https://ubuntu.com/download/mediatek-genio
PS:
We connect to the other M.2 slot, not remove the PCIe WiFi module.
Add more kernel log:

You’ll need to check the schematic, power, gpio pins for the M.2 slot and your APU PCIe device at first. Then check the power on, reset, resume sequence for each pins for the APU PCIe device. Have you already get these documents (datasheets) from the APU module maker?
You’ll need also require oscilloscope to debug these power up signaling to make sure the APU module is working and could response handshake with PCIE host controller.
By the way, Genio 1200 has only one M.2 Slot for PCIE. Where is the second M.2 slot?
