George Oikonomou 332d56ac11 Make some CC2538 CFLAGS and LDFLAGS common
Some CFLAGS and LDFLAGS previously only enabled with SMALL=1 have
now been enabled for all builds, regardless of the value of SMALL.

Therefore, from now on, SMALL only chooses between -Os and -O2
2014-01-31 20:02:43 +00:00
George Oikonomou a63376f8be Use -Os for CC2538 builds
As discussed in #503, -Os was broken with one of the toolchains
recommended in the platform's README and for that reason we were
using -O2 by default.

This commit sets the default to -Os and updates the README to no
longer recommend the toolchain in question

Benoît Thébaudeau 42c287f363 cc2538: lpm: Fix build for LPM_CONF_ENABLE == 0
lpm.c needs to #include lpm.h in order to get the definition of
lpm_periph_permit_pm1_func_t, which made the replacement macros conflict with
the function definitions for the LPM_CONF_ENABLE == 0 case. This change fixes
this issue by #if-ing out the code in lpm.c in that case. Also, the replacement
macro for lpm_register_peripheral() was missing in that case, which is fixed
here.

Benoît Thébaudeau a562acb160 cc2538: Fix library linkage
If a project needs to use some libraries at link stage, then the corresponding
linker options (e.g. '-lm') have to be passed after any .o file depending on
these libraries. Hence, LDFLAGS cannot be used to add such options when invoking
$(LD) in Makefile.cc2538, or it should be moved to the correct location.
Instead, this change adds TARGET_LIBFILES to the correct location, like most
other Contiki targets.

Benoît Thébaudeau 37e73894f1 cc2538: Move SoC data to a dedicated section to save space
Some SoC data requires huge alignments. E.g., the µDMA channel control table has
to be 1024-byte aligned. This table was simply aligned to 1024 bytes in the C
code, which had the following consequences, wasting a lot of RAM:
 - As this table could be placed anywhere in .bss, there could be an alignment
   gap of up to 1023 bytes between the preceding data and this table.
 - The size of this table was also aligned to 1024 bytes, regardless of
   UDMA_CONF_MAX_CHANNEL, making this configuration option supposed to save RAM
   just useless.
 - .bss was also aligned to at least 1024 bytes, creating a huge alignment gap
   between .data and .bss.

Instead of relying on the compiler to force this alignment, and on the linker to
automatically place data, this change places carefully such SoC data in RAM
using the linker script. A dedicated section is created to place such SoC data
requiring huge alignments, and it is put at the beginning of the SRAM in order
to ensure a maximal alignment without any gap. In this way, the alignment of
.bss also remains normal, and the size of this table is not constrained by its
alignment, but only by its contents (i.e. by UDMA_CONF_MAX_CHANNEL).

In the case of the µDMA channel control table, the data is still zeroed by
udma_init() (instead of also being zeroed as part of .bss).

Benoît Thébaudeau ab4b955f17 cc2538: Sort link input sections by alignment to optimize size
Normally, the linker does not sort files and sections matched by wildcards, so
they are placed in the order in which they are seen during link. If numerous
objects with different alignments are mixed, or if objects with unusually large
alignments are present, this very likely leads to a lot of space being wasted
because of accumulated alignment gaps.

This commit forces input sections to be sorted by alignment (unless this is
overridden by the linker script), which decreases the number and the size of
alignment gaps, thus saving space.

For a typical Contiki project, this change saves nearly 1 kiB, mainly in .bss.

Note that this behavior is only enabled if the SMALL make variable is set to 1,
because this makes more sense for a size optimization.

Benoît Thébaudeau e1147ec787 cc2538: Set the type of the .nrdata output section to NOLOAD
The .nrdata section is volatile, so its initialization must be controlled by the
application, and not be automatically done by the startup code. It should
neither be zeroed like .bss, nor be initialized from data in flash memory like
.data. This was already supposed to be the case, but the output section type of
.nrdata was not set to NOLOAD, causing the generated ELF .nrdata section header
to be of type PROGBITS instead of NOBITS, i.e. load data was generated to be
programmed in RAM, thus producing huge unprogrammable .bin files.

Oliver Schmidt 63725eff36 Merge remote-tracking branch 'upstream/master' 2013-12-12 20:46:43 +01:00
Oliver Schmidt 3b2173e01f Have CBM DOS filetype of imported files match the one used by cc65.
CFS_WRITE implies O_TRUNC which is implemented on CBM DOS by deleting an
exsisting file. Hoewever this succeeds only if the CBM DOS filetype matches.

We need a working O_TRUNC in order to be able to overwrite the contiki.cfg
configuration file.

Note: Now it has be clarified why overwriting the configuration file started to
fail the CBM PFS (platform file system) can be activated for the recently added
ethconfig program.

Benoît Thébaudeau 5261bb861d cc2538: lpm: Fix RTIMER_NOW() upon wake-up
When returning from PM1/2, the sleep timer value (used by RTIMER_NOW()) is not
up-to-date until a positive edge on the 32-kHz clock has been detected after the
system clock restarted. To ensure an updated value is read, wait for a positive
transition on the 32-kHz clock by polling the SYS_CTRL_CLOCK_STA.SYNC_32K bit,
before reading the sleep timer value.

Because of this RTIMER_NOW() fixup, lpm_exit() has to be called at the very
beginning of ISRs waking up the SoC. This also ensures that all clocks and
timers are enabled at the correct frequency and updated before using them
following wake-up.

Without this fix, etimers could sometimes (randomly, depending on timings)
become ultra slow (observed from 10x to 40x slower than normal) if the system
exited PM1/2 very often. This issue occurred more often with PM1.
