Communication via FBK in uuu/ufb #42

Closed Grinimod closed 6 years ago

Grinimod commented 6 years ago

Hi, currently I am not able to receive/process FBK (ucmd) messages on my device. The first sent data package is 

0000   80 74 0b fb 1a 95 ff ff 53 03 01 0a 01 00 2d 00
0010   8f dc 51 5b 00 00 00 00 b9 c0 02 00 8d ff ff ff
0020   0f 00 00 00 0f 00 00 00 00 00 00 00 00 00 00 00
0030   00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
0040   55 43 6d 64 3a 65 63 68 6f 20 48 65 6c 6c 6f

(USB URB_BULK captured by wireshark) of which the last line translates to the command UCmd:echo Hello Running the ufb client on the imx will result in reading from /dev/utp* forever in the main-loop.

I expect my custom linuxrc to be insufficient, so I would kindly ask for a minimal example utilizing only uuu (single UDC)

FYI: I am using yocto krogoth but an update to rocko is pending

What's type storage do you want to program. Most storage program can be finished in uboot. 

    mkdir /sys/kernel/config/usb_gadget/g1
cd /sys/kernel/config/usb_gadget/g1
echo 0x066F > idVendor
echo 0x9BFF > idProduct
mkdir strings/0x409

if [ -e /sys/devices/soc0/soc_uid ]; then
    cat /sys/devices/soc0/soc_uid > strings/0x409/serialnumber
else
    echo 0000000000000000 > strings/0x409/serialnumber
fi

echo "FSL i.MX Board" > strings/0x409/product
mkdir configs/c.1
echo 5 > configs/c.1/MaxPower

echo 1 > os_desc/use
echo "MSFT100" > os_desc/qw_sign
echo 0x40 > os_desc/b_vendor_code

mkdir functions/ffs.utp
mkdir /dev/usb-utp
mount -t functionfs utp /dev/usb-utp
ln -s functions/ffs.utp configs/c.1/
ln -s configs/c.1 os_desc

you can check here if there are /dev/usb-utp/ep0

if no, kernel have not built in ffs gadget support.

    ufb /dev/usb-utp/ep0 &

echo run utp at /dev/usb-utp$2/ep0;
while [ ! -e /dev/usb-utp/ep1 ]
do
    echo "."
    sleep 1;
done

echo  "you udc gadget controller"  > UDC

I tried 

#!/bin/sh
export PATH=/sbin:/bin:/usr/sbin:/usr/bin

mount -t sysfs none /sys
mount -t proc none /proc
mount -t devtmpfs none /dev
mount -t configfs none /sys/kernel/config

modprobe sysflags

# disable turn off display
echo -e "\033[9;0]" > /dev/tty0

#mkdir -p /myconf/config/usb_gadget/g1
#cd /myconf/config/usb_gadget/g1
mkdir -p /sys/kernel/config/usb_gadget/g1
cd /sys/kernel/config/usb_gadget/g1

echo 0x066F > idVendor
echo 0x9BFF > idProduct
mkdir -p strings/0x409
echo 0000000000000000 > strings/0x409/serialnumber
echo "FSL i.MX Board" > strings/0x409/product
mkdir -p configs/c.1
echo 5 > configs/c.1/MaxPower

mkdir os_desc
echo 1 > os_desc/use
echo "MSFT100" > os_desc/qw_sign
echo 0x40 > os_desc/b_vendor_code

mkdir -p functions/ffs.utp
mkdir  /dev/usb-utp
mount -t functionfs utp /dev/usb-utp
ln -s functions/ffs.utp configs/c.1/
ln -s configs/c.1 os_desc

resulting in

mkdir: can't create directory 'functions/ffs.utp': No such file or directory
mount: mounting utp on /dev/usb-utp failed: No such device
ln: configs/c.1/ffs.utp: No such file or directory

Switching the config location will only leave the mount failing.

To answer your questions above, there is eMMC to flash: fuses to burn and partitions to fill and tests to run, which can be done atm by ucl2 scripts in the old MFGTool on windows.

Many thanks!

Check your kernel config if CONFIG_USB_F_FS=y

Grinimod commented 6 years ago

It was initially not set, setting it to yes seems to not have any impact.

The full initial USB kernel config was

Grinimod commented 6 years ago

Problem lies in kernel config, my changes never made it into the build/.config, because

Value of CONFIG_USB_CONFIGFS is redefined by fragment ***/usb-otg.cfg.sanitized:
Previous value: # CONFIG_USB_CONFIGFS is not set
New value: CONFIG_USB_CONFIGFS=y

but somehow the changes got overridden (merge_log.txt & mismatch.txt)

Value requested for CONFIG_USB_CONFIGFS not in final .config
Requested value:  CONFIG_USB_CONFIGFS=y
Actual value:     # CONFIG_USB_CONFIGFS is not set

As CONFIG_USBCONFIGFS is not set, all following * are not even mentioned, which is consistent. Tried to manipulate the .config and start the kernel package at -C compile, but that left me with numerous inconsistent choice states.

I tried -c menuconfig, but was not able to locate the parameters that way yet.

A last trial could be to inject a whole working .config (+apply needed customization patches for own kernel modules) to continue the flow and fix the kernel config build afterwards.

Grinimod commented 6 years ago

Got it corrected via:

  1. Path in menuconfig Device Drivers       USB support              USB gadget support (very last entry)                     USB Gadget Drivers (...)                            USB functions configurable through configfs                                   Mass storage                                   Function filesystem (functionFS)

  2. Diffed the result and added that to usb-otg.cfg

  3. build/.config now contains

CONFIG_USB_HID=y CONFIG_USB_OHCI_LITTLE_ENDIAN=y CONFIG_USB_SUPPORT=y CONFIG_USB_COMMON=y CONFIG_USB_ARCH_HAS_HCD=y CONFIG_USB=y CONFIG_USB_DEFAULT_PERSIST=y CONFIG_USB_EHCI_HCD=y CONFIG_USB_EHCI_ROOT_HUB_TT=y CONFIG_USB_EHCI_TT_NEWSCHED=y CONFIG_USB_EHCI_PCI=y CONFIG_USB_EHCI_MXC=y CONFIG_USB_CHIPIDEA=y CONFIG_USB_CHIPIDEA_OF=y CONFIG_USB_CHIPIDEA_PCI=y CONFIG_USB_CHIPIDEA_UDC=y CONFIG_USB_CHIPIDEA_HOST=y CONFIG_USB_PHY=y CONFIG_USB_MXS_PHY=y CONFIG_USB_GADGET=y CONFIG_USB_GADGET_VBUS_DRAW=2 CONFIG_USB_GADGET_STORAGE_NUM_BUFFERS=2 CONFIG_USB_LIBCOMPOSITE=y CONFIG_USB_F_MASS_STORAGE=y CONFIG_USB_F_FS=y CONFIG_USB_CONFIGFS=y CONFIG_USB_CONFIGFS_MASS_STORAGE=y CONFIG_USB_CONFIGFS_F_FS=y

In the end it did solve the mount problem:

/dev/usb-utp:
dr-x------    1 root     root             0 Jan  1 00:00 .
drwxr-xr-x    5 root     root          2560 Jan  1 00:00 ..

Good So I can close this issue
