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 …
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 !
