Sata port multiplier not working in Banana pi M2U

Hey, Is there is a way to make sata port multiplier work on Banana Pi ?. I want to make Small Nas server with 3 Hard Drives (kind of old)

You can only try it at the Banana Pi & Pro
fine. if it works?

there is no /boot/boot.cmd in OS. /boot is empty

as root
nano /boot/boot.cmd

git clone && cd jmb321-sata-port-multiplier && chmod +x


i didn’t work on banana pi m2u :frowning: is there is a way to make it work in m2u ?

Wrong, port multipliers still work with R40/V40 just the same way as with A20 years ago:
