External USB does not work on BPI-M2 Berry

Banana Pi SBCs design BPI-M2 Ultra / BPI-M2 Berry(A40i)

I have an issue with an external USB Drive: Once connecting it works for some minutes, but after a short time I see in dmesg the following:

Also tried an USB-Y-Cable with externel USB power Supply, but will not work either. Anybody who tried an external HDD with the BPI?

2

everything works well

3

What kind of power supply are you using? Does your external HDD has its own Power Supply?

(I’m using Micro USB PS)

4

I’m using a 2A Power Supply with Micro USB. I tried with a different HDD, but no difference. The external HDD does not have a power supply, and it has a USB 3.0 connection. I also tried an Y-Cable to get more power, but that doesn’t help either …

5

What I noticed is, that the error occours mostly when longer write action is performed. Speaks for power issue … but how to solve?

6

The worse thing is also - once the issue came, I need to reboot the machine, as it doesn’t can been forced back to work …

7

I have exactly the same problem on a BPI-M2 Ultra. I tried a couple of different HDD closures with the same result, also I tried with different disk without any improvement.

As you said the problem is when you trying write operations, once the error happens it freezes for 2-5min and the it remount the filesystem as readonly, the only way to recover from that I found is just to reboot the whole system.

Unfortunately I don’t have a fix for it :frowning:

Same for me… I moved the usb drives to an other sbc… Before this, I have tried several hard drives, also ssd and usb stick… of course different power supplies… Always the same writing a big bunch of data to a USB drive will crash the connection to the drive… I think it is not a power issue, I think it is timing issue… Actually have posted this issue months ago, without any response…

I have the same problems … the connection to my USB drive crahes during intensive write access. It’s a WD-Elements harddrive with external power supply! Therefore it can’t be a power problem (the drive works fine on any other computer).

System: Debian Stretch 3.10.107 2017-08-28

Here are the messages from syslog:

Does anybody have an idea how to get more system information about this issue?

I also tested “Ubuntu mate 3.10.108 2017-11-13” with the same error. Could it be a hardware defect?

Thanks a lot!

Does anyone has any news or a clue on what’s going on?

11

I guess I found a solution - I had the following entry in /etc/fstab for the external HDD:

LABEL=DATA /data xfs rw,user,exec,auto,nofail 0 2

I just thought about, that it could be relying to a cache overflow of some kind, so I have added wsync to disable the cache:

LABEL=DATA /data xfs rw,user,exec,auto,nofail,wsync 0 2

And so, I didn’t got the issue since a couple of days (keep fingers crossed …)

12

Okay, the previous thing does it not solve entirely - next thing looks promisiing: hdparm -W 0 /dev/sda1 So afterwards I was able to save huge files without issues.

13

It seems so: hdparm -W 0 /dev/sda1 did it

14

hello, Did you use sata => usb to connect M2 Berry? and have this problem?

Did you try on board sata interface?

15

No, I’m using the “normal” USB-Interface to connect to an external USB-HDD. As the external HDD is capsuled, i didn’t have even the chance to connect to the SATA port.

16

could you take a picture? and please tell me what is your USB HDD device , I’ll do a test, thanks.
