I have sucessfully used an XTRX in PCIe x1 with my CM4 board. To do that, requirements are:

config.txt must be updated by adding dtoverlay=pcie-32bit-dma to this file to force DMA to be 32bits
in xtrx_linux_pcie_drv VA_DMA_ADDR_FIXUP must be defined. Unlike rk3399, without this workaround there is no kernel panic but samples are wrong.

Good evening @trabucayre I have done what you suggested and still cannot make it work. Any other hint?
