A Sector Map Parameter Table contains a sequence of the following
descriptors:
* (Optional) configuration detection command descriptors, one for
each command to run to determine the current configuration. This
exists only if the flash layout is configurable.
* Sector map descriptors, one for each possible configuration. On
a flash device with a non-configurable layout, there is only one
such descriptor.
Previously we only supported the non-configurable case with a single
descriptor. This commit adds support for multiple configurations.
The second byte of the sector map descriptor is the configuration ID.
On a device with non-configurable layout, the only available map
descriptor's configuration ID must be 0x00 as required by the
JESD216D standard. This value is important, because we will check
each descriptor's configuration ID when we support multiple
configurations.
Note: The test data is fake - when we modified real data of a
configurable device to become non-configurable for test purpose, we
forgot to change this field.
The SFDP functions parse SFDP data which is fetched by a callback
called `sfdp_reader` provided by {SPIF,QSPIF,OSPIF}BlockDevice.
Currently, this callback interface only takes a read address and an RX
buffer to store output data. This has been enough, because other SPI
parameters are always the same when fetching the SFDP table only -
they are just hardcoded in each reader.
But in the future we will add support for flash devices with multiple
configurations (in a subsequent commit), and to detect which
configuration is enabled, we will need to send detection commands
which require device-dependent SPI parameters:
* address size
* instruction
* dummy cycles
This commit
* turns the above SPI parameters from predefined/hardcoded values
into parameters of the callback
* lets the SFDP functions pass the above parameters to the callback
(Note: To read the SFDP table itself, those values are constants
defined by the standard, not tied to any particular device, so they
can be known to the SFDP functions)
* updates the callbacks implemented by {SPIF,QSPIF,OSPIF}BlockDevice
* updates the mock callback for unit tests and expectations
The test case for multithreaded erase/program/read allocates a few
Thread objects from the heap and starts them. It has a few problems:
* To check that there will be enough heap to start a new thread, the
test case tries to allocate a dummy buffer of the thread's heap size
and then frees it, before starting the thread. Then the thread will
allocate its own stack. Such check is not reliable, because threads
that are already running also perform additional allocation (when
running `test_thread_job()`) and may take away the memory we just
checked.
* When deleting all threads in a loop, the loop boundary misses the
last thread if the last thread object was allocated but not started
(i.e. due to failed thread stack allocation check).
To fix the issues
* Start a thread without any allocation test. Following the preceding
commit "rtos: Thread: Make stack allocation failure runtime catchable",
`Thread::start()` now returns `osErrorNoMemory` if stack allocation
fails which we can handle.
* Store pointers to all threads in a zero-initialized array, and
free all elements at the end of the test.
Add tests for `sfdp_parse_sector_map_table()` which currently (at the
time of this commit) supports flash devices with
* no Sector Map Parameter Table (i.e. the whole flash is uniform and
non-configurable)
* a single descriptor in the Sector Map Parameter Table (i.e. the
flash layout is non-configurable and has multiple regions)
Support and unit tests for flashes with multiple configurable layouts
will be added in the future.
Note: The implementation of `sfdp_parse_sector_map_table()` assumes
the table to be valid if read succeeds, so the SFDP reader callback
needs to ensure it reads data correctly or return an error.
Individual libraries' `target_h` stub headers have now all been moved
from `mbed-headers-base` to `mbed-headers-<library>`.
Note: Even though headers previously in `target_h` are technically
stubs/fakes too, they are used by not only unit tests but also regular
libraries when compiled for unit tests, because no target-specific HAL
implementation exists in this case. In order for regular library
sources to pick up `target_h` headers, those headers must
* have the same names as regular headers
* appear first in include paths
This is why those headers are part of `mbed-headers-<library>` and not
`mbed-stubs-<library>`. Before this refactoring, `mbed-headers-base`
was the first in unit tests' include paths.
Previously a test executable was recognised as a single test by CTest.
However, test executables usually contain multiple test cases, the
results of the test cases should be individually reported. With our
previous setup we could miss test case failures that didn't cause the
executable to return an error code.
This commit uses gtest_discover_test to discover all test cases in a
test executable. This enables CTest to match test passes and failures
from the googletest binary output.
The CMake target `mbed-headers` brings in all headers, and we are
gradually moving away from it and explicitly use only headers needed
by each unit test.
The header `mbed.h` pulls in headers from a number of Mbed OS
components that are not necessarily used. It was intended for user
applications only, and libraries and unit tests should explicitly
include library headers it uses to limit dependencies.
This change avoids having to link unnecessary libraries in storage
unit tests' CMake definitions.
Move storage stubs from UNITTESTS/stubs into components inside the
top-level storage directory. Specifically,
* storage/blockdevice/tests/UNITTESTS/doubles/ for BlockDevice stubs.
* storage/kvstore/filesystemstore/tests/UNITTESTS/ for a stub used by
the FileSystemStore test. The stub has been renamed from
kv_config_stub.cpp to filesystemstore_kv_config_stub.cpp, to make it
evident why it doesn't go into storage/kvstore/kv_config/.
Assumption that greentea test file is always named main.cpp is
incorrect. Updated mbed_greentea_add_test() macro to make TEST_SOURCES
parameter compulsory, which is used to specify greentea test
file(s). This allows tests to use C, or have a different name.
Therefore also updated all pre-existing greentea test CMake files to
explicity add main.cpp to TEST_SOURCES.
- Remove redundant cmake script as already added the CMake configuration file
- Remove redundant empty_baseline as it is no longer needed with the help of CMake configuration file
- ChainingBlockModuleTest test case compares two strings with EXPECT_EQ
which normally compare strings residing memory address so replaced it with EXPECT_STREQ to compare strings.
Add license identifier to files which Arm owns the copyright to,
and contain either BSD-3 or Apache-2.0 licenses. This is to address
license errors raised by scancode analysis.
To allow overriding of the boot stack size from the Mbed configuration
system, consistently use MBED_CONF_TARGET_BOOT_STACK_SIZE rather than
MBED_BOOT_STACK_SIZE.
Fixes#10319
Previously we get the common erase size of the whole flash, which
may or may not exists if there are multiple regions. In this case
the size returned is zero and the test fails.
Fix this by allocating read and write buffers that are large enough
for all sectors. The test itself already supports non-uniform
erase sizes, and the erase size at any address can be smaller
than our buffers.
The test case only uses one specific sector, but the erase size
is obtained for the whole block device instead. This doesn't work
if different regions of the flash don't have a common erase size.
Fix the issue by getting the erase size at the address we use.
