stm32/mboot: Add support for erase/read/write of external SPI flash.2018-06-22T05:30:34+00:00Damien Georgedamien.p.george@gmail.com2018-06-22T05:30:34+00:00urn:sha1:ec7982ec6dc195a6b1381af2a18590414ef9e621
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.
stm32/qspi: Don't require data reads and writes to be a multiple of 4.2018-06-22T05:07:01+00:00Damien Georgedamien.p.george@gmail.com2018-06-22T05:07:01+00:00urn:sha1:7f41f73f0f81e0ecbdb37d32ea7ad8cbc7468b06
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.
stm32/boards/NUCLEO_F091RC: Fix TICK_INT_PRIORITY so it is highest prio.2018-06-20T02:24:18+00:00Damien Georgedamien.p.george@gmail.com2018-06-20T02:23:46+00:00urn:sha1:561ae9a91bebac3184596cefc85f5cea82974aae
Fixes issue #3880.
stm32/mboot: Define constants for reset mode cycling and timeout.2018-06-19T13:23:17+00:00Damien Georgedamien.p.george@gmail.com2018-06-19T13:23:17+00:00urn:sha1:5962c210c59c21cd1641bac9d7a84c3a4a8b0cf6
And fix timeout value so that it does actually finish with reset_mode=1.
stm32/spi: Fix SPI driver so it can send/recv more than 65535 bytes.2018-06-18T07:41:14+00:00Damien Georgedamien.p.george@gmail.com2018-06-18T07:36:52+00:00urn:sha1:e49cd106b4bbbb47b782f73b66000df6094f7afe
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.
