how to enable mtp&adb at same time

[Roy996]

Hi, thanks for your project! I've run MTP on my board. But I met some trouble when I tried to enable mtp&adb at same time.

My script for adb is:
adb.txt
And it runs pretty well without function MTP.
However, it doesn't work when I tried to enable both of them.

When goes to these lines
mkdir /dev/ffs-mtp
mount -t functionfs mtp /dev/ffs-mtp
mkdir /dev/usb-ffs
mkdir /dev/usb-ffs/adb
mount -o uid=2000,gid=2000 -t functionfs adb /dev/usb-ffs

According to logs,
mount: mounting adb on /dev/ffs-mtp failed: No such file or directory

Do you have any ideas about this?

Thanks!

But why you have
<<mount: mounting adb on /dev/ffs-mtp failed: No such file or directory>> : (/dev/ffs-mtp)

When the mount command was
<<mount -o uid=2000,gid=2000 -t functionfs adb /dev/usb-ffs>> : (/dev/usb-ffs) ?

adb seems to try to use the mtp mount point for some reasons...

Have a look to umtprd-ffs.sh

To enable adb uncomment the lines "#mkdir functions/acm.usb0" and "#ln -s functions/acm.usb0 configs/c.1"
and try to change acm to adb

It works now!!!
I messed up the mount point.
Here is my scripts:
**mkdir functions/ffs.mtp
mkdir functions/ffs.adb
...
ln -s functions/ffs.mtp configs/b.1/ffs.mtp
ln -s functions/ffs.adb configs/b.1/ffs.adb
...
mkdir /dev/usb-ffs
mkdir /dev/usb-ffs/mtp
mkdir /dev/usb-ffs/adb
mount -o uid=1024,gid=1024 -t functionfs mtp /dev/usb-ffs/mtp
mount -o uid=2000,gid=2000 -t functionfs adb /dev/usb-ffs/adb

umtprd &

adbd &**

Both mtp and adb run base the "ffs", so changing acm.usb0 to adb.usb0 doesn't work.

Thanks :)
