RockPro64 + SATA Port Multiplier

Recommended Posts

Hi I need help,
I have used in the past the Banana PI M1 card for many years with a SATA Port Multiplier.
To enable PMP support for this card, you had to edit:

 

nano /boot/boot.cmd

 

Go to line that starts with:

 

setenv bootargs and  add at the bottom of the row:

 

ahci_sunxi.enable_pmp=1


recompile with:

 

mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr

 

Restart Almbian and the SATA Port Multiplier was activated.

 

 

I now own a RockPro64 with Armbian and a 6-port PCIE sata card.

Should buy a card with 8-10 ports to add hdd that I will need to make backups.

At the moment, however, I would like to enable PMP support also on this card so that I can immediately install the backup disks because they are urgent because a disk has problems.

 

The procedure described above for Banana PI does not work, I believe it is due to a different CPU architecture.

 

Before Kernel 4.x on the "banana pi" you had to recompile the kernel, could you tell me what is the exact procedure to enable PMP support also on Rockchip RK3399 with 4.4.213 kernel?

Thank you
