![]() 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.
