Before, if the semaphore recieved a wait of zero, the semaphore
would erronously drop the ticker event to wake up the device,
causing the device to go to sleep without any mechanism to wake
itself up.
During a dispatch operation, the event queue dispatches all events
that have expired, so the call to equeue_sema_wait very rarely
has a wait of zero. But this can happen when an event is posted
just after a dispatch has occured.
Originally the ethernet ISR would be linked in to all mbed-os based
firmware because it was named ENET_IRQHandler() so that it would be
automatically placed in the FLASH image's interrupt vector table. This
meant that programs which made no use of the lwIP stack still pulled in
this ISR.
This commit changes the name of the routine so that the ISR isn't
automatically placed in the interrupt vector table at link time but is
instead dynamically placed in the interrupt vector table at runtime
when the lwIP stack is initialized. Now the ethernet ISR is only linked
in when it is actually needed.
Example arm-none-eabi-size output for a simple LED blinking program
showing the before and after size results:
text data bss dec hex filename
13208 148 7784 21140 5294 LPC1768/HelloWorld.elf
text data bss dec hex filename
12700 148 7468 20316 4f5c LPC1768/HelloWorld.elf
stop using scope for \addtogroup. It was placing class methods into the
group documentation instead of the class documentation. The new style is
to explicitly tag the class as @ingroup. This new method will allow the
class to be linked in the group page, and the class page will contain
the detailed documentation of the class methods.
The input format is now determined by the OUTPUT_EXT key in
targets.json, and defaults to "bin" when not specified. This changes the
Teensy3_1 and the NRF51x targets' post bulid hooks.
Teensy3_1 just converted to intelhex, so we do nothing instead.
NRF51x assumed that it was taking in a bin format file. I made it detect
file type by extension.
The current implementation of semihost_disabledebug() hangs when used
with mbed interface firwmare revision 21164, the first version which
added support for this semihost call. I encountered this hang when
running a Release build on my mbed-LPC1768 board as the RTOS attempted
to disable the debugger before the idle thread put the CPU to sleep.
The 21164 interface firmware expects that R1 points to a valid argument
block but the current implementation passes in NULL. The fix was to
pass in a dummy block which is ignored by the newer 141212 revision of
the firmware and allows the 21164 version to proceeed without halting
the CPU until a manual reset.
Before this fix semihost_disabledebug() did work with the latest
mbed interface firmware revision 141212 but I rarely use this revision
of the interface firmware due to the instability issues I have
encountered in the past with its CDC and LocalFileSystem functionality.
With this proposed fix, the code now works with both the 21164 and
141212 revisions of the mbed interface firmware on the mbed-LPC1768.
The extra space between "--no_wrap_diagnostics" and "-e" is inconsistent with the development and release targets.
It bugs people (like me) that have little OCD tics 😉.
* Update i2c driver to tackle multiple I2C object instances on different pins
* Update pinmap to enable the extra peripherals of EFx32xG12 over EFx32xG1
targets.json contained a key for some targets, `OUTPUT_EXT`, which I
moved to `Target`, the root of all targets. Following on that, the tools
now use this extension provided by `OUTPUT_EXT` to determine the file
type of the output executable.
