   1 DFU TEST CASE DESCRIPTION:
   2
   3 The prerequisites for running this script are assured by dfu_gadget_test_init.sh.
   4 In this file user is able to generate their own set of test files by altering
   5 the default set of TEST_FILES_SIZES variable.
   6 The dfu_gadget_test_init.sh would generate test images only if they are not
   7 already generated.
   8
   9 Moreover, on a target device the "dfu_alt_info" env variable should be extended
  10 to have "dfu_test.bin fat 0 6;" \ entry ([1]). For reference please consult the
  11 config file for TRATS/TRATS2 devices (./include/configs/trats{2}.h)
  12
  13 One can use fat, ext4 or any other supported file system, which can be
  14 created in a convenient way with exporting partitions via UMS (ums 0 mmc 0)
  15 and using standard tools on host (like mkfs.ext4).
  16
  17 Example usage:
  18 1. On the target:
  19    env default -a
  20    dfu 0 mmc 0
  21 2. On the host:
  22    ./dfu_gadget_test.sh 11 [test_file]
  23
  24 where 11 is the mumber of alt setting corresponding to entry [1] and [test_file]
  25 is an optional parameter, with which one can explicitly indicate the test file
  26 to be used.
  27
  28 The number of the alt setting entry can be obtained with dfu-util -l command.
  29 In its output one should look for the 'name="dfu_test1.bin"' and corresponding
  30 alt=11.
