dfu-util allows filtering on USB device vendor:product ID by using the -d flag (-d 0451:d022). Such option is very handy when many DFU devices are connected to a single host PC. This commit allows testing when above situation emerges.

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.
