Damien George c551169bd8 stm32/mboot: Add hook to run board-specific code early on startup. 2019-02-15 15:34:05 +11:00
Damien George 3669198403 stm32/mboot: Add support script which can program mboot and application. 2019-02-15 15:09:59 +11:00
Damien George 3d0c31e60e stm32/mboot: Move some BSS vars to new section that isn't zeroed out.
Zeroing out data on startup takes time and is not necessary for certain
variables.  So provide a declaration for such variables and use it.

Damien George ff04b78ffd stm32/mboot: Add support for loading gzip'd firmware from a filesystem.
This adds support to mboot to load and program application firmware from
a .dfu.gz file on the board's filesystem.  See mboot/README.md for details.

Damien George be4e5b1f87 stm32/mboot/mphalport.h: Include genhdr/pins.h for access to pin names.
So that mboot configuration can use names like pyb_pin_X1.

Damien George f38397ba8d stm32/mboot/Makefile: Generate all pin header files from board pins.csv. 2019-02-14 13:36:32 +11:00
Damien George 26a1ae295f stm32/mboot/Makefile: Support specifying BOARD_DIR for custom board. 2019-02-14 00:01:14 +11:00
Damien George 03a8b1cc50 stm32/mboot: Allow deploying via deploy-stlink. 2019-02-07 16:06:05 +11:00
Damien George a81cb3576b stm32/mboot: Add support for GPIO ports G, H, I and J. 2019-02-07 16:04:48 +11:00
Damien George 39eb1e9f81 stm32/mboot: Add support for STM32F769 MCUs. 2019-02-07 16:04:06 +11:00
Damien George 9570297dd1 stm32/mboot: Use USB HS as main USB device regardless of USB_HS_IN_FS. 2019-02-07 16:03:18 +11:00
Damien George e5509a910f stm32/mboot: Add option to autodetect the USB port that DFU uses.
Enable in mpconfigboard.h via #define MBOOT_USB_AUTODETECT_USB (1).
Requires MICROPY_HW_USB_FS and MICROPY_HW_USB_HS to be enabled as well.

Damien George a1c81761b1 stm32/mboot: Add documentation for using mboot on PYBv1.x. 2018-12-04 23:48:47 +11:00
Damien George eed522d69f stm32/mboot: Add support for 4th board LED. 2018-12-04 23:14:30 +11:00
Damien George 13e92e1225 stm32/mboot: Provide led_state_all function to reduce code size. 2018-12-04 23:11:51 +11:00
Andrew Leech 17f7c683d2 stm32: Add support for STM32F765xx MCUs.
This part is functionally similar to STM32F767xx (they share a datasheet)
so support is generally comparable.  When adding board support the
stm32f767_af.csv and stm32f767.ld should be used.

Damien George a23719e0ad stm32/mboot/main: Use correct formula for DFU download address.
As per ST's DfuSe specification, and following their example code.

Damien George 5f3016c663 stm32/mboot/Makefile: Use -Wno-attributes for ll_usb.c HAL source file.
A recent version of arm-none-eabi-gcc (8.2.0) will warn about unused packed
attributes in USB_WritePacket and USB_ReadPacket.  This patch suppresses
such warnings for this file only.

Damien George 9b158d60e1 stm32/mboot: Always use a flash latency of 1WS to match 48MHz HCLK. 2018-06-26 00:06:04 +10:00
Damien George 967123d42e stm32/mboot: Only compile in code for the USB periph that is being used.
Prior to this patch, if both USB FS and HS were enabled via the
configuration file then code was included to handle both of their IRQs.
But mboot only supports listening on a single USB peripheral, so this patch
excludes the code for the USB that is not used.

Damien George 37c4fd3b50 stm32/mboot: Fix bug with invalid memory access of USB state.
Only one of pcd_fs_handle/pcd_hs_handle is ever initialised, so if both of
these USB peripherals are enabled then one of these if-statements will
access invalid memory pointed to by an uninitialised Instance.  This patch
fixes this bug by explicitly referencing the peripheral struct.

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 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.
2018-06-19 23:23:17 +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 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 15ddc20436 stm32: Add new component, the mboot bootloader.
Mboot is a custom bootloader for STM32 MCUs.  It can provide a USB DFU
interface on either the FS or HS peripherals, as well as a custom I2C
bootloader interface.
