Damien George 04c7cdb668 stm32: Enter bootloader via a system reset.
Entering a bootloader (ST system bootloader, or custom mboot) from software
by directly branching to it is not reliable, and the reliability of it
working can depend on the peripherals that were enabled by the application
code.  It's also not possible to branch to a bootloader if the WDT is
enabled (unless the bootloader has specific provisions to feed the WDT).

This patch changes the way a bootloader is entered from software by first
doing a complete system reset, then branching to the desired bootloader
early on in the start-up process.  The top two words of RAM (of the stack)
are reserved to store flags indicating that the bootloader should be
entered after a reset.

Damien George b80bccccff esp32/modnetwork: Still try to reconnect to WLAN even with AUTH_FAIL.
WIFI_REASON_AUTH_FAIL does not necessarily mean the password is wrong, and
a wrong password may not lead to a WIFI_REASON_AUTH_FAIL error code.  So to
improve reliability connecting to a WLAN always reconnect regardless of the
error.

Damien George 34c04d2319 py/nlrthumb: Save and restore VFP registers s16-s21 when CPU has them.
These s16-s21 registers are used by gcc so need to be saved.  Future
versions of gcc (beyond v9.1.0), or other compilers, may eventually need
additional registers saved/restored.

See issue #4844.

Damien George 3ee3995be1 esp32: Update to use ESP IDF v3.3-beta3.
This updates ESP IDF to use v3.3-beta3.  And also adjusts README.md to
point to stable docs which provide a link to download the correct toolchain
for this IDF version, namely 1.22.0-80-g6c4433a-5.2.0

Chris Mason 14cf91f704 stm32: In link script, define start of stack separately from heap end.
Previously the end of the heap was the start (lowest address) of the stack.
With the changes in this commit these addresses are now independent,
allowing a board to place the heap and stack in separate locations.

Damien George 8b18cfedee stm32/usbd_msc: Allow to compile when USB enabled and SD card disabled. 2019-06-11 21:01:14 +10:00
Damien George 53200247b7 stm32/usb: Add "msc" kw-arg to pyb.usb_mode to select MSC logical units.
With this the user can select multiple logical units to expose over USB MSC
at once, eg: pyb.usb_mode('VCP+MSC', msc=(pyb.Flash(), pyb.SDCard())).  The
default behaviour is the original behaviour of just one unit at a time.

Damien George 9e68eec8ea stm32/usb: Use ARG_xxx enums to access kw args in pyb_usb_mode. 2019-06-11 15:50:21 +10:00
Damien George 38bcc99a58 stm32/usbd_msc: Provide Mode Sense response data in MSC interface.
Eventually these responses could be filled in by a function to make their
contents dynamic, depending on the attached logical units.  But for now
they are fixed, and this patch fixes the MODE SENSE(6) responses so it is
the correct length with the correct header.

Damien George 829aa58c5c stm32/usbd_msc: Provide custom irquiry processing by MSC interface.
So the MSC interface can customise the inquiry response based on the
attached logical units.
2019-06-11 15:43:58 +10:00
Damien George 518aa571ab stm32/usbd_msc: Rework USBD MSC code to support multiple logical units.
SCSI can support multiple logical units over the one interface (in this
case over USBD MSC) and here the MSC code is reworked to support this
feature.  At this point only one LU is used and the behaviour is mostly
unchanged from before, except the INQUIRY result is different (it will
report "Flash" for both flash and SD card).

Damien George 9d3031cc9d tools/mpy-tool.py: Fix linking of qstr objects in native ARM Thumb code.
Previously, when linking qstr objects in native code for ARM Thumb, the
index into the machine code was being incremented by 4, not 8.  It should
be 8 to account for the size of the two machine instructions movw and movt.
This patch makes sure the index into the machine code is incremented by the
correct amount for all variations of qstr linking.

See issue #4829.

Damien George fd839221fd stm32/boards/PYBD_SFx: Enable ussl module using mbedTLS. 2019-06-05 15:38:01 +10:00
Damien George fed4c23590 stm32: Integrate optional mbedTLS component for ussl module.
To use it a board should define MICROPY_PY_USSL=1 and MICROPY_SSL_MBEDTLS=1
at the Makefile level.  With the provided configuration it adds about 64k
to the build.

Damien George 9d72f07b6d unix/mpconfigport.mk: Update comment about TLS implementations.
As long as the submodule is checked out, mbedTLS is now fully integrated
into the unix build if MICROPY_SSL_MBEDTLS=1.
2019-06-05 15:28:30 +10:00
Damien George 678ec182cd extmod/extmod.mk: Integrate mbedTLS so it is built from source.
Setting MICROPY_PY_USSL and MICROPY_SSL_MBEDTLS at the Makefile-level will
now build mbedTLS from source and include it in the build, with the ussl
module using this TLS library.  Extra settings like MBEDTLS_CONFIG_FILE may
need to be provided by a given port.

If a port wants to use its own mbedTLS library then it should not set
MICROPY_SSL_MBEDTLS at the Makefile-level but rather set it at the C level,
and provide the library as part of the build in its own way (see eg esp32
port).

Yonatan Goldschmidt 7cf26ca4bd py/obj: Optimise small-int comparison to 0 in mp_obj_is_true.
Instead of converting to a small-int at runtime this can be done at compile
time, then we only have a simple comparison during runtime.  This reduces
code size on some ports (e.g -4 on qemu-arm, -52 on unix nanbox), and for
others at least doesn't increase code size.

Damien George faf3d3e9e9 tools/mpy-tool.py: Fix linking qstrs in native code, and multiple files.
Fixes errors in the tool when 1) linking qstrs in native ARM-M code; 2)
freezing multiple files some of which use native code and some which don't.

Fixes issue #4829.

Damien George ce8262a164 stm32/modnetwork: Replace generic netif NIC polling with specific code.
It doesn't work to tie the polling of an underlying NIC driver (eg to check
the NIC for pending Ethernet frames) with its associated lwIP netif.  This
is because most NICs are implemented with IRQs and don't need polling,
because there can be multiple lwIP netif's per NIC driver, and because it
restricts the use of the netif->state variable.  Instead the NIC should
have its own specific way of processing incoming Ethernet frame.

This patch removes this generic NIC polling feature, and for the only
driver that uses it (Wiznet5k) replaces it with an explicit call to the
poll function (which could eventually be improved by using a proper
external interrupt).

Nicko van Someren 8e3af7d4c8 esp32: Add machine.SDCard class using built-in HW SD/MMC controller.
This adds support for SD cards using the ESP32's built-in hardware SD/MMC
host controller, over either the SDIO bus or SPI.  The class is available
as machine.SDCard and using it can be as simple as:

    uos.mount(machine.SDCard(), '/sd')

Martin Dybdal de76f73d34 esp32/machine_timer: Reuse Timer handles, deallocate only on soft-reset.
The patch solves the problem where multiple Timer objects (e.g. multiple
Timer(0) instances) could initialise multiple handles to the same internal
timer.  The list of timers is now maintained not for "active" timers (where
init is called), but for all timers created.  The timers are only removed
from the list of timers on soft-reset (machine_timer_deinit_all).

Fixes #4078.
