Rock 5b+ Both PCIE Slots

Hi,

I’m attempting to use both pcie slots (bottom) on my rock5b+ running Armbian v25.2 running Linux 6.1.84-vendor-rk35xx.

I’m testing using a Mediatek 7925 wifi card. It works on the bottom side middle slot (M-KEY1) but when I have it on the bottom slide upper slot (M-KEY2). I get some errors on startup:

rock5b login: [. 14.573256] rk-pcie fe150000.pcie: failed to initialize host [ 16.061459] Bluetooth: hci1: command 0xfc18 tx timeout [ 16.062360] Bluetooth: hci1: BCM: Reset failed (-110) [ 33.981660] [GTP-ERR] [__do_register_ext_module:79] Module [goodix-fwu] timeout

And it is not recognzied when I do lspci . Is there a something I need to install to be able to use both PCIe slots?

Thanks!
