The old open/opendir functions did not provide a route for errors and
relied on implementations manually setting errno. Updated to return
errors directly.
Required for other representations of FileSystems, ie LocalFileSystem
Introduces FileSystemHandle for the same behaviour as FileHandle and
DirHandle.
Requires the following to hook into file/dir lookup:
```
int open(FileHandle **file, const char *filename, int flags)
int open(DirHandle **dir, const char *path)
```
This hook is provided by the FileSystem class, so requires no changes
from implementations.
This is necessary for support of block devices with >512 byte
blocks, such as most SPI flash parts.
- Enabled support of up to 4096 byte blocks
- Added support for heap-backed buffers using _FS_HEAPBUF
- Necessary to avoid stack overflows
- Avoids over-aggresive allocations of _MAX_SS
- Enabled _FS_TINY to further reduce memory footprint
- Haven't found a downside for this yet except for possible
thread contention
Add the attribute flash to enable priority inheritance and robust mode.
The robust flag allows mutexes held by terminated threads to be
properly released.
Wrap the file mbed_rtos_storage.h in extern "C". This allows the
functions inside rtx_lib.h to have correct definitions when included
in a C++ file.
This is required for the RTX5 error trapping.
Trigger an assert if a file is read from or written to from an
interrupt handler or critical section. This includes using printf
from an interrupt handler or critical section. This makes failures
due to use in incorrect context deterministic and easier to locate.
This feature is enabled by defining MBED_TRAP_ERRORS_ENABLED to 1 or
by using the debug profile.
External EMAC drivers are currently directly attaching to lwip_stack.c
via mbed_lwip_bringup et al. Restore the original prototypes to avoid
compatibility breakage.
This is temporary, as this test does not fit to some 16kB RAM devices. This requires few more steps: some small devices are using big async HAL structures, RTX changes increased the RAM footprint, plus this test seems to be too big. With all these, it won't fit in RAM regions for some devices.
* Initialization clear interrupt status
* Remove state in management of interrupt
* Handle timestamp in the past
* Handle current seconds, even if out of the relative timestamp.
* Simplify interrupt handling logic.
Certain public APIs are being added to mbed.h so as to make them
part of namespace mebd.
APIs being added are:
* drivers/UARTSerial.h
* platform/ATCmdParser.h
* platform/mbed_poll.h
* netsocket/nsapi_ppp.h
