CC_FASTCALL was introduced many years ago for the cc65 tool chain. It was never used for another tool chain. With a798b1d648 the cc65 tool chain doesn't need CC_FASTCALL anymore.
The CC2538 the WDT cannot be stopped once it has been started.
The CC2530/1 WDT can be stopped if it is running in timer mode,
but it cannot be stopped once it has been started in watchdog mode.
Both platforms currently provide "dummy" implementations of `watchdog_stop()`,
one does nothing and the other one basically re-maps `_stop()` to
`_periodic()`.
This was originally done in order to provide implementations for all prototypes
declared in `core/dev/watchdog.h`. In hindsight and as per the discussion
in #1088, this is bad practice since, if the build succeeds, the caller will
expect that the WDT has in fact been stopped, when in reality it has not.
Since the feature (stopping the WDT) is unsupported by the hardware, this pull
removes those dummy implementations. Thus, we will now be able to reliably
detect - at build time - attempts at using this unsupported feature.
Those two warnings are optimisation-related
* 110 warns that an always-false if branch has been optimised out
* 126 warns about unreachable code which also gets optimised out
In disabling those warnings, we make the build less cluttered
This was used in the past because sdld was
very verbose when linking banked hex files. New
sdld versions do not exhibit this level of
verbosity and therefore the redirect can be
stopped
The CC2531 USB stick now identifies itself as a
'Texas Instruments CC2531 USB Dongle' and uses a
TI-assigmed VID:PID. The VID:PID is now configurable
in contiki- or project-conf.h
The sensinode platform does not support .upload and .serialdump
Their presence in the makefile has confused in the past confused
some users. This commit removes them
The commit also removes the $(OBJECTDIR)/%.rel: %.cS recipe which
is not used by either 8051 platform and is probably broken anyway,
since it has been unmaintained for years
Historically $(OBJECTDIR) was created when Makefile.include is read. A
consequence is that combining "clean" with "all" (or any other build
target) results in an error because the clean removes the object
directory that is required to exist when building dependencies.
Creating $(OBJECTDIR) on-demand ensures it is present when needed.
Removed creation of $(OBJECTDIR) on initial read, and added an order-only
dependency forcing its creation all Makefile* rules where the target is
explicitly or implicitly in $(OBJECTDIR).
This is mainly a naming convention thing, we want to have 'isr'
as part of the name, instead of 'int'. We also want port_2 instead
of p2 because we already had port_1
See Pull Request #18
The P2 Interrupt is shared across many periferal (I2C, USB, GPIO).
This adds a generic interrupt handler on which the differents drivers
can register a handler.
See Pull Request #18
Change to have a real usb VID/PID and better fit the capabilities
of the CC2531 hardware (enpoint size, location).
Compile only if the cdc-acm class is requested.
See Pull Request #18
- Moved to their own file
(so we can later copy the entire thing over to cc2430)
- Renamed the functions
(for naming convention reasons)
- The entire thing can be enabled/disabled
- Added a couple more macros
- Hooked into main()
__bit variables must be located after the 0x20 address
This force the stack to start after 0x20, thus decrease
the stack size by a considerable amount.
This add -fomit-frame-pointer by default, it decrease sliglty the
stack usage when several function call are nested.
On some specific case 30 bytes could be saved on the stack.
