fd13ce5e60 stm32/mboot: Add support for H7 MCUs, with H743 flash layout. 2019-04-08 14:33:57 +10:00

5688c9ba09 stm32/usb: Allow to override USB strings & VID/PID in app and mboot.
The override #define's should go in the board's mpconfigboard.h file.

c551169bd8 stm32/mboot: Add hook to run board-specific code early on startup. 2019-02-15 15:34:05 +11:00

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.

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.

9570297dd1 stm32/mboot: Use USB HS as main USB device regardless of USB_HS_IN_FS. 2019-02-07 16:03:18 +11:00

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.

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.

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

9b158d60e1 stm32/mboot: Always use a flash latency of 1WS to match 48MHz HCLK. 2018-06-26 00:06:04 +10:00

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.

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.

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.

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.

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.

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.

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.
