Try adding `dtoverlay=pcie-32bit-dma` to your `/boot/config.txt` and reboot.
That overlay helps with PCIe devices like the Coral TPU on the Pi 4. After reboot, check if it's detected with `lspci`.
If `lspci` doesn’t show anything, it could also be a hardware issue. Make sure the Coral TPU is firmly seated in the PCIe slot and powered properly. On some setups, it won’t even show up if the connection is loose or the PSU isn't delivering enough current.
