Actually you can use any other clm info blob with this firmware as I tried. I also uploaded this to armbian's firmware repo. Hope we could get the proper firmware uploaded by Broadcom soon.

I realize it might not be easy to get an answer internally but this chipset is likely to appear in more RK3588 SBCs soon since it's the one on the evb. > >-Andy > >> Shengyu
