Rock3a PCIe fails while using eMMC

#1

Hi, I tried using eMMC with Rock 3a.
I bought a 64Gb eMMC module. This one ( https://www.aliexpress.com/item/4000419649482.html?spm=a2g0o.order_list.0.0.5b1818021F5CDG )

After that, I download and flash img from ( https://github.com/radxa-build/rock-3a/releases/tag/main-a7204124 )

file: [rock-3a-ubuntu-focal-server-arm64-20220501-0200-gpt.img.xz]

But when I try to boot, I see PCIe Link Fail.

you can try to remove ”broadcom-wifibt-firmware" if you didn’t use it
when i using rock-3a-debian-buster-xfce4-arm64-20220401-0150-gpt.img and upgrade the ”broadcom-wifibt-firmware" package i will facing the same error

What does this warning mean?
I also have this message in all the firmware that I used.
