It allows SPI flash to be programmed via a USB DFU utility in the same way that internal MCU flash is programmed. stm32/mboot: Define constants for reset mode cycling and timeout. 2018-06-19T13:23:17+00:00 Damien George damien.p.george@gmail.com 2018-06-19T13:23:17+00:00 urn:sha1:5962c210c59c21cd1641bac9d7a84c3a4a8b0cf6 And fix timeout value so that it does actually finish with reset_mode=1. stm32/mboot: Adjust user-reset-mode timeout so it ends with mode=1. 2018-06-18T02:23:27+00:00 Damien George damien.p.george@gmail.com 2018-06-18T02:23:27+00:00 urn:sha1:ceff433fccb3f12b9ae39a726e4893366481822a 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. stm32/mboot: Increase USB rx_buf and DFU buf sizes to full 2048 bytes. 2018-06-08T05:29:52+00:00 Damien George damien.p.george@gmail.com 2018-06-08T05:29:52+00:00 urn:sha1:24c416cc66577a2cfbe8d6f01e1386340fc042f4 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. stm32: Add new component, the mboot bootloader. 2018-05-24T13:21:19+00:00 Damien George damien.p.george@gmail.com 2018-05-24T13:15:20+00:00 urn:sha1:15ddc2043687942c68d9ab54176fd837f44d3083 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.
