I tried ASM2806 on Radxa ROCK 5B (RK3588). https://gist.github.com/RadxaNaoki/640e47d377add9fe38301de164d4058e It doesn't work on PCIe 2.0 (M.2 E Key), but it does work on PCIe 3.0 (M.2 M Key). Could you try PCIe 2.0 slot on your board? Best regards, -- FUKAUMI Naoki Radxa Computer (Shenzhen) Co., Ltd.
