1 | DFU TEST CASE DESCRIPTION: |
2 | ||
7ad67e55 SW |
3 | The prerequisites for running this script are assured by |
4 | dfu_gadget_test_init.sh, which is automatically invoked by dfu_gadget_test.sh. | |
a4c86bbb ŁM |
5 | In this file user is able to generate their own set of test files by altering |
6 | the default set of TEST_FILES_SIZES variable. | |
7 | The dfu_gadget_test_init.sh would generate test images only if they are not | |
8 | already generated. | |

10 | On the target device, environment variable "dfu_alt_info" must contain at |
11 | least: | |
a4c86bbb | 12 | |
7ad67e55 SW |
13 | dfu_test.bin fat 0 6;dfudummy.bin fat 0 6 |
14 | ||
15 | Depending on your device, you may need to replace "fat" with | |
16 | "ext4", and "6" with the relevant partition number. For reference please | |
17 | consult the config file for TRATS/TRATS2 devices | |
18 | (../../include/configs/trats{2}.h) | |
19 | ||
20 | One can use fat, ext4 or any other supported file system supported by U-Boot. | |
21 | These can be created by exporting storage devices via UMS (ums 0 mmc 0) and | |
22 | using standard tools on host (like mkfs.ext4). | |

24 | Example usage: | |
25 | 1. On the target: | |
7ad67e55 | 26 | setenv dfu_alt_info dfu_test.bin fat 0 6\;dfudummy.bin fat 0 6 |
a4c86bbb ŁM |
27 | dfu 0 mmc 0 |
28 | 2. On the host: | |

29 | test/dfu/dfu_gadget_test.sh X Y [test file name] |
30 | e.g. test/dfu/dfu_gadget_test.sh 0 1 | |
31 | or | |
32 | e.g. test/dfu/dfu_gadget_test.sh 0 1 ./dat_960.img | |
a4c86bbb | 33 | |

34 | ... where X and Y are dfu_test.bin's and dfudummy.bin's alt setting numbers. |
35 | They can be obtained from dfu-util -l or $dfu_alt_info. | |
36 | It is also possible to pass optional [test file name] to force the script to | |
37 | test one particular file. |
