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.
