Trying to boot from SATA

[AaronNGray (Aaron Gray)]

Is it possible to directly boot from SATA ?

I don’t seem to be able to do this from the uEnv.txt script.

The following is my attempt :- https://gist.github.com/AaronNGray/bde5dae82d13716ea2f19cafe75d8e26

I have also made mods in /etc/fstab in both the /boot image and on the SSD /

Banana Pi BPI-M3 New Image Release: Raspbian jessie 8.0 2018-5-28 V1.1

okay moving to SATA is very easy, I over complicated it at first due to my past implementation without the SATA module being in the kernel. Instructions :- Attach SATA drive and power to BPI bootup run ‘fdisk /sda’ and create three partitions :- sda1 a 100MB vfat partition sda2 an ext4 partition of the main paritition the bulk of the disk sda3 a 8 or 16 GB swap partition mount the SSD mkdir /mnt/sda2 mount /dev/sda2 /mnt/sda2 copy main directories from SDCard ext4 root https:…

I am trying this method and I run into the following:

root@bpi-iot-ros-ai:/home/pi# sudo chmod u+x make.sh

root@bpi-iot-ros-ai:/home/pi# ./make.sh

cp: cannot stat ‘/man’: No such file or directory

cp: cannot stat ‘/run/user/1000/gvfs’: Permission denied

Yeah, I have just got back tothis after a long time. I am sorry I found it did not work in the end due to multiple issues. TheM3 cannot be booted from SATA directly, even just mapping usr and var over using fstab runs into problems. Theres issues with the M3 SATA being routed via the USB interface internally on the board which causes latency problems and the SATA interface is too slow. I am looking at this again. But might consider possibly getting a W3 board which I think solves this.

I should have added that I am running a BPI-M2u. Armbian-config alows you to choose installation options, including SATA and seems to work well.

[AaronNGray (Aaron Gray)]

Okay, right this is the M3 forum.

[McFrisch (Rob F)]

Oh, yea. Well at least you know it doesn’t work on M2u either It looks lit is should, but I notice even after making the mods to fstab and uEvn.txt, there is a message at boot time reverting to mounting the filesystem on mmcblk0p2:

EXT4-fs (mmcblk0p2): re-mounted. Opts: errors=remount-ro

I will look for another way… thanks for your effort!
