Dan Halbert 7c219600a2 WIP: after merge; before testing 2018-07-11 16:45:30 -04:00
Damien George a2ac7e4fc9 stm32/boards: Add .ld and af.csv files for STM32F722.
These files can also be used for F723, F732 and F733 MCUs.

Damien George ec7982ec6d stm32/mboot: Add support for erase/read/write of external SPI flash.
This patch adds support to mboot for programming external SPI flash.  It
allows SPI flash to be programmed via a USB DFU utility in the same way
that internal MCU flash is programmed.

Damien George 7f41f73f0f stm32/qspi: Don't require data reads and writes to be a multiple of 4.
Prior to this patch the QSPI driver assumed that the length of all data
reads and writes was a multiple of 4.  This patch allows any length.  Reads
are optimised for speed by using 32-bit transfers when possible, but writes
always use a byte transfer because they only use a single data IO line and
are relatively slow.

Damien George 561ae9a91b stm32/boards/NUCLEO_F091RC: Fix TICK_INT_PRIORITY so it is highest prio.
Fixes issue #3880.

Damien George 5962c210c5 stm32/mboot: Define constants for reset mode cycling and timeout.
And fix timeout value so that it does actually finish with reset_mode=1.

Damien George e49cd106b4 stm32/spi: Fix SPI driver so it can send/recv more than 65535 bytes.
The DMA peripheral is limited to transferring 65535 elements at a time so
in order to send more than that the SPI driver must split the transfers up.

The user must be aware of this limit if they are relying on precise timing
of the entire SPI transfer, because there might be a small delay between
the split transfers.

Fixes issue #3851, and thanks to @kwagyeman for the original fix.

rolandvs ca2b1d6b36 stm32/boards/NUCLEO_F091RC: Add Arduino-named pins and rename CPU pins.

rolandvs 0d3de68669 stm32/boards/stm32f091_af.csv: Split labels that are multiple funcs. 2018-06-18 13:05:24 +10:00
Damien George ceff433fcc stm32/mboot: Adjust user-reset-mode timeout so it ends with mode=1.
If the user button is held down indefinitely (eg unintenionally, or because
the GPIO signal of the user button is connected to some external device)
then it makes sense to end the reset mode cycle with the default mode of
1, which executes code as normal.

Damien George 7be4a23c0c stm32/i2cslave: Fix ordering of event callbacks in slave IRQ handler.
It's possible (at least on F4 MCU's) to have RXNE and STOPF set at the same
time during a call to the slave IRQ handler.  In such cases RXNE should be
handled before STOPF so that all bytes are processed before
i2c_slave_process_rx_end() is called.

Damien George bc5e8a2cb6 stm32/i2c: Fix num_acks calculation in i2c_write for F0 and F7 MCU's.
Due to buffering of outgoing bytes on the I2C bus, detection of a NACK
using the ISR_NACKF flag needs to account for the case where ISR_NACKF
corresponds to the previous-to-previous byte.

Damien George cc5a94044a drivers/memory/spiflash: Rename functions to indicate they use cache.
This patch renames the existing SPI flash API functions to reflect the fact
that the go through the cache:

    mp_spiflash_flush -> mp_spiflash_cache_flush
    mp_spiflash_read  -> mp_spiflash_cached_read
    mp_spiflash_write -> mp_spiflash_cached_write

Damien George 565f590586 ports: Enable IOBase on unix, stm32, esp8266 and esp32.
It's a core feature, in particular required for user-streams with uasyncio.

Damien George b2fa1b50ed ports: Call gc_sweep_all() when doing a soft reset.
This calls finalisers of things like files and sockets to cleanly close
them.

Damien George 24c416cc66 stm32/mboot: Increase USB rx_buf and DFU buf sizes to full 2048 bytes.
The DFU USB config descriptor returns 0x0800=2048 for the supported
transfer size, and this applies to both TX (IN) and RX (OUT).  So increase
the rx_buf to support this size without having a buffer overflow on
received data.

With this patch mboot in USB DFU mode now works with dfu-util.

Damien George 190c7dba89 stm32/mpconfigport.h: Enable DELATTR_SETATTR and BUILTINS_NOTIMPLEMENTED
MICROPY_PY_DELATTR_SETATTR can now be enabled without a performance hit for
classes that don't use this feature.

MICROPY_PY_BUILTINS_NOTIMPLEMENTED is a minor addition that improves
compatibility with CPython.
2018-06-08 12:55:18 +10:00
Damien George 93150a0d40 ports: Enable descriptors on stm32, esp8266, esp32 ports.
They are now efficient (in runtime performance) and provide a useful
feature that's hard to obtain without them enabled.

See issue #3644 and PR #3826 for background.

Damien George 7d86ac6c01 stm32: Add network driver for Wiznet5k using MACRAW mode and lwIP.
The Wiznet5k series of chips support a MACRAW mode which allows the host to
send and receive Ethernet frames directly.  This can be hooked into the
lwIP stack to provide a full "socket" implementation using this Wiznet
Ethernet device.  This patch adds support for this feature.

To enable the feature one must add the following to mpconfigboard.mk, or
mpconfigport.mk:

    MICROPY_PY_WIZNET5K = 5500

and the following to mpconfigboard.h, or mpconfigport.h:

    #define MICROPY_PY_LWIP (1)

After wiring up the module (X5=CS, X4=RST), usage on a pyboard is:

    import time, network
    nic = network.WIZNET5K(pyb.SPI(1), pyb.Pin.board.X5, pyb.Pin.board.X4)
    nic.active(1)
    while not nic.isconnected():
        time.sleep_ms(50) # needed to poll the NIC
    print(nic.ifconfig())

Then use the socket module as usual.

Compared to using the built-in TCP/IP stack on the Wiznet module, some
performance is lost in MACRAW mode: with a lot of memory allocated to lwIP
buffers, lwIP gives Around 750,000 bytes/sec max TCP download, compared
with 1M/sec when using the TCP/IP stack on the Wiznet module.

Damien George d9f1ecece2 stm32/modnetwork: Provide generic implementation of ifconfig method.
All it needs is a lwIP netif to function.

Damien George 7437215ad7 stm32/modnetwork: Change base entry of NIC object from type to base.
mod_network_nic_type_t doesn't need to be an actual uPy type, it just needs
to be an object.
2018-06-01 13:31:28 +10:00
Damien George 6d87aa54d6 stm32/modnetwork: Don't take netif's down when network is deinited.
It should be up to the NIC itself to decide if the network interface is
removed upon soft reset.  Some NICs can keep the interface up over a soft
reset, which improves usability of the network.

rolandvs 958fa74521 stm32/boards: Ensure USB OTG power is off for NUCLEO_F767ZI.
And update the GPIO init for NUCLEO_H743ZI to consistently use the mphal
functions.

rolandvs 50bc34d4a4 stm32/boards: Split combined alt-func labels and fix some other errors.
Pins with multiple alt-funcs for the same peripheral (eg USART_CTS_NSS)
need to be split into individual alt-funcs for make-pins.py to work
correctly.

This patch changes the following:
- Split `..._CTS_NSS` into `..._CTS/..._NSS`
- Split `..._RTS_DE` into `..._RTS/..._DE`
- Split `JTDO_SWO` into `JTDO/TRACESWO` for consistency
- Fixed `TRACECK` to `TRACECLK` for consistency

Damien George f497723802 stm32: Allow to have no storage support if there are no block devices.
If no block devices are defined by a board then storage support will be
disabled.  This means there is no filesystem provided by either the
internal flash or external SPI flash.  But the VFS system can still be
enabled and filesystems provided on external devices like an SD card.

bootloader interface.

Damien George cda964198a stm32: Integrate lwIP as implementation of usocket module.
This patch allows to use lwIP as the implementation of the usocket module,
instead of the existing socket-multiplexer that delegates the entire TCP/IP
layer to the NIC itself.

This is disabled by default, and enabled by defining MICROPY_PY_LWIP to 1.

When enabled, the lwIP TCP/IP stack will be included in the build with
default settings for memory usage and performance (see
lwip_inc/lwipopts.h).  It is then up to a particular NIC to register itself
with lwIP using the standard lwIP netif API.
