Damien George afecc124e6 py: Fix location of VM returned exception in invalid opcode and comments
The location for a returned exception was changed to state[0] in

Damien George 6d19934463 py: Get optional VM stack overflow check compiling and working again.
Changes to the layout of the bytecode header meant that this debug code was
no longer compiling.  This is now fixed and a new compile-time option is
introduced, MICROPY_DEBUG_VM_STACK_OVERFLOW, to turn on this feature (which
is disabled by default).  This option is needed because more than one file
needs to cooperate to make this check work.

Damien George b33f108cde stm32/sdcard: Properly reset SD periph when SDMMC2 is used on H7 MCUs. 2018-12-30 01:28:34 +11:00
Dave Hylands c932639063 tools/pydfu.py: Fix regression so tool runs under Python 2 again.
Under python3 (tested with 3.6.7) bytes with a list of integers as an
argument returns a different result than under python 2.7 (tested with
2.7.15rc1) which causes pydfu.py to fail when run under 2.7.  Changing
bytes to bytearray makes pydfu work properly under both Python 2.7 and
Python 3.6.

roland 4d8504425a stm32/modmachine: Fix reset_cause to correctly give DEEPSLEEP on L4 MCU.
Before this fix it returned SOFT_RESET after waking from a deepsleep
(standby).

Damien George f334816df0 stm32/uart: Make sure user IRQs are handled even with a keyboard intr. 2018-12-30 01:03:22 +11:00
Damien George 7bdbea9a0c stm32/uart: Clear overrun error flag after reading RX data register.
On MCUs other than F4 the ORE (overrun error) flag needs to be cleared
independently of clearing RXNE, even though both are wired to trigger the
same RXNE IRQ.  In the case that an overrun occurred it's necessary to
explicitly clear the ORE flag or else the RXNE interrupt will keep firing.

Damien George 0d860fdcd0 stm32/uart: Always enable global UART IRQ handler on init.
Otherwise IRQs may not be enabled for the user UART.irq() handler.  In
particular this fixes the user IRQ_RXIDLE interrupt so that it triggers
even when there is no RX buffer.

Tobias Badertscher 06236bf28e lib/utils: Add generic MicroPython IRQ helper functions.
Initial implementation of this is taken from the cc3200 port.

Damien George fa50047bbc py/runtime: Unlock the GIL in mp_deinit function.
This mirrors what is done in mp_init.  Some RTOSs require this symmetry to
get back to a clean state (when doing a soft reset, for example).

Damien George 7cd59c5bc3 py/mpconfig: Move MICROPY_VERSION macros to static ones in mpconfig.h.
It's more robust to have the version defined statically in a header file,
rather than dynamically generating it via git using a git tag.  In case
git doesn't exist, or a different source control tool is used, it's
important to still have the uPy version number available.

Andrew Leech ce0c581179 stm32/main: Add board config option to enable/disable mounting SD card.
The new option MICROPY_HW_SDCARD_MOUNT_AT_BOOT can now be defined to 0 in
mpconfigboard.h to allow SD hardware to be enabled but not auto-mounted at
boot.  This feature is enabled by default to retain previous behaviour.

Previously, if an SD card is enabled in hardware it is also used to boot
from.  While this can be disabled with a SKIPSD file on internal flash,
this wont be available at first boot or if the internal flash gets
corrupted.

Paul Sokolovsky 5ed578e5b4 py/gc: Adjust gc_alloc() signature to be able to accept multiple flags.
The older "bool has_finaliser" gets recast as GC_ALLOC_FLAG_HAS_FINALISER=1
so this is a backwards compatible change to the signature.  Since bool gets
implicitly converted to 1 this patch doesn't include conversion of all
calls.

Paul Sokolovsky a261d8b615 py/objarray: Introduce "memview_offset" alias for "free" field of object
Both mp_type_array and mp_type_memoryview use the same object structure,
mp_obj_array_t, but for the case of memoryview, some fields, e.g. "free",
have different meaning.  As the "free" field is also a bitfield, assume
that (anonymous) union can't be used here (for the concerns of possible
compatibility issues with wide array of toolchains), and just add a field
alias using a #define.  As it's a define, it should be a selective
identifier, so use verbose "memview_offset" to avoid any clashes.

Dave Hylands 39eef27083 tools/mpy-tool.py: Fix build error when no qstrs present in frozen mpy.
If you happen to only have a really simple frozen file that doesn't contain
any new qstrs then the generated frozen_mpy.c file contains an empty
enumeration which causes a C compile time error.

Damien George 0c46419323 windows: Remove remaining traces of old GNU readline support.
GNU readline support for the unix port was removed in
acaa30b604 and in
5e83a75c78, so it's also no longer supported
in the windows port.

Damien George 814d580a15 tools/mpy-tool.py: Fix calc of opcode size for opcodes with map caching.
Following an equivalent fix to py/bc.c.  The reason the incorrect values
for the opcode constants were not previously causing a bug is because they
were never being used: these opcodes always have qstr arguments so the part
of the code that was comparing them would never be reached.

Thanks to @malinah for finding the problem and providing the initial patch.

Damien George 6bf8ecfe3a py/bc: Fix calculation of opcode size for opcodes with map caching.
All 4 opcodes that can have caching bytes also have qstrs, so the test for
them must go in the qstr part of the code.  The reason this incorrect
calculation of the opcode size did not lead to a bug is because the caching
byte is at the end of the opcode (byte, qstr, qstr, cache) and is always
0x00 when saving/loading, so was just treated as a single byte no-op
opcode.  Hence these opcodes were being saved/loaded/decoded correctly.

Thanks to @malinah for finding the problem and providing the initial patch.

Damien George dc23978dde stm32/uart: Add ability to have a static built-in UART object.
A static UART is useful for internal peripherals that require a UART and

Damien George e0c2432503 stm32/uart: Simplify deinit of UART, no need to call HAL.
The HAL just clears UE and then clears all the UART control registers.

Damien George bc3f0dddac stm32/uart: Remove HAL's UART_HandleTypeDef from UART object struct.
This UART_HandleTypeDef is quite large (around 70 bytes in RAM needed for
each UART object) and is not needed: instead the state of the peripheral
held in its registers provides all the required information.

Damien George 55830dd9bf py/objexcept: Make sure mp_obj_new_exception_msg doesn't copy/format msg
mp_obj_new_exception_msg() assumes that the message passed to it is in ROM
and so can use its data directly to create the string object for the
argument of the exception, saving RAM.  At the same time, this approach
also makes sure that there is no attempt to format the message with printf,
which could lead to faults if the message contained % characters.

Fixes issue #3004.
