PCIE error PEX_ERR_DR[CRST]

We configured our custom P3041 board as root complex mode, and connect via PCB to another PCIe device.

From u-boot, when we do enumeration, we can see another bus appear (bus 1).

Trying to read from configuration space of the other device will result in 0xffffffff no matter which address.

And error PEX_ERR_DR[CRST]  is detected.

 

What should I do to know more about the error details to troubleshoot the problem?
