BPI-M2Berry + JMB321 5 Port SATA Multiplier

Hello Guy.

I’ve buy a BPI-M2Berry + a SATA Multiplier with JMB321 and Raspbian Jessie ( i’0ve download in here: http://forum.banana-pi.org/t/bpi-m2-ultra-bpi-m2-berry-new-image-2017-08-24-raspbian-jessie-beta-bpi-m2u-sd-emmc-img).

unfortunately the JMB321 interface does not work with this kernel.

Is a solution possible?


Hi, you have to modify ahci driver and build the kernel.

Get the kernel here: https://github.com/BPI-SINOVOIP/BPI-M2U-bsp

Modify driver as described here: https://forum.armbian.com/topic/5199-banana-pi-m2u-wont-boot/?tab=comments#comment-39587 (thanks to Armbian developers)

Follow instructions how to build and install the kernel here: https://github.com/BPI-SINOVOIP/BPI-M2U-bsp/blob/master/BPI-M2Ultra_Compiler_SOP.pdf

Please note, that PMPs are not reliable. More info here: https://linux-sunxi.org/SATA#Port_multipliers

I have tested it on BPI-M2U.
