test: dfu: script enhancements
Various misc enhancements to dfu_gadget_test.sh: * After every write (download), perform a write to a different file with different data. This ensures that the DFU buffer's content is replaced, so that if the read (upload) succeeds, we know that the correct data was actually read from the storage device, rather than simply being left over in the DFU buffer. This requires two alt setting names to be passed to the script, and a dummy data file to be generated by dfu_gadget_test_init.sh. * Fix the assumption that dfu_gadget_test.sh is run from the directory that contains it, by cd'ing to that directory before invoking ./dfu_gadget_test_init.sh. * Use $DIR$RCV_DIR consistently, rather than using plain $RCV_DIR in some places. * Add 959, 961 test file sizes, to be consistent with having one more than and one less than all the other "round" sizes 64, 128, and 4096. * Remove references to $BKP_DIR from dfu_gadget_test_init.sh, since it isn't used.

DFU TEST CASE DESCRIPTION:
|
||||
|
||||
The prerequisites for running this script are assured by dfu_gadget_test_init.sh.
|
||||
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.
|
||||
|
||||
Moreover, on a target device the "dfu_alt_info" env variable should be extended
|
||||
to have "dfu_test.bin fat 0 6;" \ entry ([1]). For reference please consult the
|
||||
config file for TRATS/TRATS2 devices (./include/configs/trats{2}.h)
|
||||
On the target device, environment variable "dfu_alt_info" must contain at
|
||||
least:
|
||||
|
||||
One can use fat, ext4 or any other supported file system, which can be
|
||||
created in a convenient way with exporting partitions via UMS (ums 0 mmc 0)
|
||||
and using standard tools on host (like mkfs.ext4).
|
||||
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:
|
||||
env default -a
|
||||
setenv dfu_alt_info dfu_test.bin fat 0 6\;dfudummy.bin fat 0 6
|
||||
dfu 0 mmc 0
|
||||
2. On the host:
|
||||
./dfu_gadget_test.sh 11 [test_file]
|
||||
test/dfu/dfu_gadget_test.sh dfu_test.bin dfudummy.bin
|
||||
|
||||
where 11 is the mumber of alt setting corresponding to entry [1] and [test_file]
|
||||
is an optional parameter, with which one can explicitly indicate the test file
|
||||
to be used.
|
||||
|
||||
The number of the alt setting entry can be obtained with dfu-util -l command.
|
||||
In its output one should look for the 'name="dfu_test1.bin"' and corresponding
|
||||
alt=11.
|
||||
... where dfu_test.bin and dfudummy.bin are the names of the alt settings from
|
||||
$dfu_alt_info.
