When loading U-Boot into RAM over USB protocols using tools such as
|

tegrarcm or L4T's exec-uboot.sh/tegraflash.py, Tegra's USB device
|
||||
mode controller is initialized and enumerated by the host PC running
|

the tool. Unfortunately, these tools do not shut down the USB
|
||||
controller before executing the downloaded code, and so the host PC
|

does not "de-enumerate" the USB device. This option shuts down the
|

USB controller when U-Boot boots to avoid leaving a stale USB device

present.

DFU TEST CASE DESCRIPTION:
|
||||
|
||||
The prerequisites for running this script are assured by
|
||||
dfu_gadget_test_init.sh, which is automatically invoked by dfu_gadget_test.sh.
|
||||
In this file user is able to generate their own set of test files by altering
|
||||
the default set of TEST_FILES_SIZES variable.
|
||||
The dfu_gadget_test_init.sh would generate test images only if they are not
|
||||
already generated.
|
||||
|
||||
On the target device, environment variable "dfu_alt_info" must contain at
|
||||
least:
|
||||
|
||||
dfu_test.bin fat 0 6;dfudummy.bin fat 0 6
|
||||
|
||||
Depending on your device, you may need to replace "fat" with
|
||||
"ext4", and "6" with the relevant partition number. For reference please
|
||||
consult the config file for TRATS/TRATS2 devices
|
||||
(../../include/configs/trats{2}.h)
|
||||
|
||||
One can use fat, ext4 or any other supported file system supported by U-Boot.
|
||||
These can be created by exporting storage devices via UMS (ums 0 mmc 0) and
|
||||
using standard tools on host (like mkfs.ext4).
|
||||
|
||||
Example usage:
|
||||
1. On the target:
|
||||
setenv dfu_alt_info dfu_test.bin fat 0 6\;dfudummy.bin fat 0 6
|
||||
dfu 0 mmc 0
|
||||
2. On the host:
|
||||
test/dfu/dfu_gadget_test.sh X Y [test file name] [usb device vendor:product]
|
||||
e.g. test/dfu/dfu_gadget_test.sh 0 1
|
||||
or
|
||||
e.g. test/dfu/dfu_gadget_test.sh 0 1 ./dat_960.img
|
||||
or
|
||||
e.g. test/dfu/dfu_gadget_test.sh 0 1 0451:d022
|
||||
or
|
||||
e.g. test/dfu/dfu_gadget_test.sh 0 1 ./dat_960.img 0451:d022
|
||||
|
||||
... where X and Y are dfu_test.bin's and dfudummy.bin's alt setting numbers.
|
||||
They can be obtained from dfu-util -l or $dfu_alt_info.
|
||||
It is also possible to pass optional [test file name] to force the script to
|
||||
test one particular file.
|
||||
If many DFU devices are connected, it may be useful to filter on USB
|
||||
vendor/product ID (0451:d022).
|
||||
One can get them by running "lsusb" command on a host PC.

sudo test/ums/ums_gadget_test.sh VID PID PART_NUM [-f FILE_SYSTEM] [test_file]

e.g. sudo test/ums/ums_gadget_test.sh 0525 a4a5 6 -f vfat ./dat_14M.img
|

|
||||
... where:
|
||||
VID - UMS device USB Vendor ID
|
||||
PID - UMS device USB Product ID
|
||||
PART_NUM - is the partition number on which UMS operates or "-" to use the
|
||||
whole device
|
||||
|
||||
Information about available partitions on the target one can read with using
|
||||
the 'mmc part' or 'part list' commands.
|
||||
|
||||
The partition num (PART_NUM) can be specified as '-' for using the whole device.
|
||||
|
||||
The [-f FILE_SYSTEM] optional switch allows for formatting target partition to
|
||||
FILE_SYSTEM.
|
||||
|
||||
The last, optional [test_file] parameter is for specifying the exact test file
|
||||
to use.
