J721EXSOMXEVM: After connecting a PCI expansion card to the J721E, the system reports an error during startup.

Part Number: J721EXSOMXEVM

Since the PCIe2 slot is damaged, I want to use the PCI expansion card to connect multiple EP devices. However, after plugging in the expansion card, the J721E shows the error on boot:
bridge configuration invalid ([bus 00-00]), reconfiguring; SError Interrupt on CPU1, code 0x00000000bf000000 -- SError.

I tested multiple SDK versions ( like 10.00.00.08 and 09.00.00.08) but the error persists.

However, this expansion card works normally when connected to development boards from other brands without this issue.
