i.mx6 sabresd working with kernel 4.14.x

Gibbio commented 5 years ago

Hello everybody, great project, thanks for sharing. Played a bit with my Freescale i.mx6 sabresd dev board and I got it running. Used Kernel 4.14.86 (not working with v4.1.5 from Freescale) My start script is:

modprobe gadgetfs
mkdir /dev/gadget
mount -t gadgetfs gadgetfs /dev/gadget
/usr/bin/umtprd

My modded conf is:

loop_on_disconnect 1
wait 1
usb_dev_path   "/dev/gadget/2184000.usb"
usb_epin_path  "/dev/gadget/ep1in"
usb_epout_path "/dev/gadget/ep2out"
usb_epint_path "/dev/gadget/ep3in"

Hope this help!

Thanks for the feedback ! Have you tried the FunctionFS mode ?

Gibbio commented 5 years ago

Hello, im testing right now, but isn't working. My modded conf is:

usb_functionfs_mode 0x1

usb_dev_path   "/dev/ffs-umtp/ep0"
usb_epin_path  "/dev/ffs-umtp/ep1"
usb_epout_path "/dev/ffs-umtp/ep2"
usb_epint_path "/dev/ffs-umtp/ep3"

the umtprd-ffs.sh script give an error on line 38: ash: write error: No such device

If I start the daemon i get:

Nothing appears on dmesg on both host/client

Just edited to let you know that im using a very customized kernel/os so maybe something is missing.

jfdelnero commented 5 years ago

Replace the line 38 in umtprd-ffs.sh with this one :

ls  /sys/class/udc/ > cfg/usb_gadget/g1/UDC

then restart the system and retry.

Gibbio commented 5 years ago

Yes, it's working, I just have to put a sleep 1 after starting the daemon before line 38. So the script looks like:

modprobe libcomposite

mkdir cfg
mount none cfg -t configfs

mkdir cfg/usb_gadget/g1
cd cfg/usb_gadget/g1

mkdir configs/c.1

mkdir functions/ffs.umtp
mkdir functions/acm.usb0

mkdir strings/0x409
mkdir configs/c.1/strings/0x409

echo 0x0100 > idProduct
echo 0x1D6B > idVendor

echo "01234567" > strings/0x409/serialnumber
echo "Viveris Technologies" > strings/0x409/manufacturer
echo "The Viveris Product !" > strings/0x409/product

echo "Conf 1" > configs/c.1/strings/0x409/configuration
echo 120 > configs/c.1/MaxPower

ln -s functions/acm.usb0 configs/c.1
ln -s functions/ffs.umtp configs/c.1

mkdir /dev/ffs-umtp
mount -t functionfs umtp /dev/ffs-umtp
/usr/bin/umtprd &

cd ../../..

sleep 1

ls /sys/class/udc/ > cfg/usb_gadget/g1/UDC
