In VStartSimpleLinkSpawnTask we change xTaskCreate to xTaskCreateStatic
so that the task is created using statically allocated memory for the TCB
and stack.
This means that xTaskCreate function is no longer needed (the static
version is now used exclusively).
This function is no longer used. Having the .boot section attribute
meant that it was included in the firmware regargless of use. Without
this attribute the linker can remove the function.
This allows to statically allocate the TCB (thread control block) and
thread stack in the BSS segment, reducing the need for dynamic memory
allocation.
This is a pristine copy (actually a subset of files) of upstream FreeRTOS
v9.0.0.
Modifications to the previous version of FreeRTOS (v8.1.2) included
addition of __attribute__ ((section (".boot"))) to the following
functions:
pxPortInitialiseStack
prvTaskExitError
prvPortStartFirstTask
xPortStartScheduler
vPortSetupTimerInterrupt
xTaskGenericCreate
vTaskStartScheduler
prvInitialiseTCBVariables
prvInitialiseTaskLists
prvAllocateTCBAndStack
This attribute will need to be reinstated on a case-by-case basis
because some of the above functions are now removed/changed.
A standard I2C address is 7 bits but addresses 0b0000xxx and 0b1111xxx
are reserved. The scan() method is changed to reflect this, along with
the docs.
- add template rule that converts a specified source file into a qstring file
- add special rule for generating a central header that contains all
extracted/autogenerated strings - defined by QSTR_DEFS_COLLECTED
variable. Each platform appends a list of sources that may contain
qstrings into a new build variable: SRC_QSTR. Any autogenerated
prerequisities are should be appened to SRC_QSTR_AUTO_DEPS variable.
- remove most qstrings from py/qstrdefs, keep only qstrings that
contain special characters - these cannot be easily detected in the
sources without additional annotations
- remove most manual qstrdefs, use qstrdef autogen for: py, cc3200,
stmhal, teensy, unix, windows, pic16bit:
- remove all micropython generic qstrdefs except for the special strings that contain special characters (e.g. /,+,<,> etc.)
- remove all port specific qstrdefs except for special strings
- append sources for qstr generation in platform makefiles (SRC_QSTR)
Properly calculate the period and the prescaler, this now allows to
set the PWM frequency down to 5Hz. Make Timer IDs go from 0 to 3.
Add the trigger definitions for the channel IRQ.
The first argument to the type.make_new method is naturally a uPy type,
and all uses of this argument cast it directly to a pointer to a type
structure. So it makes sense to just have it a pointer to a type from
the very beginning (and a const pointer at that). This patch makes
such a change, and removes all unnecessary casting to/from mp_obj_t.
To let unix port implement "machine" functionality on Python level, and
keep consistent naming in other ports (baremetal ports will use magic
module "symlinking" to still load it on "import machine").
Fixes#1701.
This makes select.poll() interface fully compatible with CpYthon. Also, make
their numeric values of these options compatible with Linux (and by extension,
with iBCS2 standard, which jopefully means compatibility with other Unices too).
The default setting of using the "highest" method available doesn't
work with some servers like Microsoft Azure. TLSV1 seems to work with
pretty much any server.
