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.	2018-06-08 15:29:52 +10:00
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.	2018-05-24 23:21:19 +10:00

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.

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.
