SATA activation on M2U


#1

Hi everybody,

I have recently bought a Banana PI M2Ultra I have implemented 2017-05-25-raspbian-jessie-preview3-bpi-m2u-sd-emmc.img I boot on eMMC

my questions are : 1- how to boot on eMMC when an USB key is already connected ? 2- most important : my little 320Go HDD connected to SATA port is not recognized ! have you already a solution ?

Thanks in advance Sorry for my poor English (I’am French)

For question 2 : i have just understood the reason why …

http://linux-sunxi.org/Sinovoip_Banana_Pi_M2_Ultra The SATA power port is directly wired to DC-DC so connected disks will neither be powered when running on battery nor when users try to power BPi M2 Ultra through the Micro USB port. Without an appropriate PSU with 4.0mm/1.7mm barrel plug you can forget about powering a disk from the board.

So i will bought the appropriate device !
