Robert Fisk	7e073a091d	Sleep instead of busy-wait, approx 50% power reduction!	8 years ago
Robert Fisk	cb6a861341	Implement flash write lockout by spamming the unlock register, then ... checking that the correct unlock sequence fails.	9 years ago
Robert Fisk	1262c5337a	All tabs to spaces	9 years ago
Robert Fisk	08e6846cc5	Add missing option to clock configuration	9 years ago
Robert Fisk	21de622469	Added hardware check on bootup: fault LED will light if Upstream ... firmware is placed on Downstream hardware or vice versa.	9 years ago
Robert Fisk	2983da24b2	Changed Upstream and Downstream SPI transfers back to DMA. DMA works ... correctly now, either because SPI is in 16-bit mode, or because I found all the other bugs! Doubled SPI baudrate to 10.5Mbps. Transfer speed now limited (again) by Downstream's lack of FIFO buffering in the USB host controller. Also disabled DMA transaction half-complete interrupt in stm32f4xx_hal_dma.c, as it wasn't doing anything useful.	9 years ago
Robert Fisk	58308c4a89	Added Mozilla Public License information to file headers. ... Mozilla Public License v2.0 is compatible with the various licenses used by ST and ARM.	9 years ago
Robert Fisk	ce03845623	Completed moving Upstream to interrupt-based SPI. ... Although I am not entirely convinced this is necessary, as the SPI data stall issue only appeared with optimisation off (-O0). Perhaps re-visit this if Upstream needs more free CPU time later...	9 years ago
Robert Fisk	f24714cd8c	Revisit Upstream project to: ... - Implement Upstream state machine, with Downstream-dependent device emulation - Add fault LED flashing - Improve fault handling and freakouts - Misc bug fixes	9 years ago
Robert Fisk	4350666330	Refactor a bunch of stuff in Upstream project to avoid endless confusion ... with Downstream project. Also fixed a couple of things in upstream_spi.c and upstream_interface_msc.c but due to file rename the diff is not obvious...	9 years ago
Robert Fisk	503d79de56	Streamlining Downstream project	9 years ago
Robert Fisk	69d1490faa	Upstream debugged and working again, emulating a 128MB storage device. ... Implemented mock downstream_interface_msc.c for debugging purposes. Multiple bugfixes and tweaks to: - downstream_interface_msc.c - downstream_spi.c - usbd_core.c - usbd_msc.c - usbd_msc_scsi.c - stm32f4xx_hal_pcd.c	9 years ago
Robert Fisk	d3da69eb07	Draft implementation of downstream SPI interface. Significant mods ... required to USB MSC class, mainly in usbd_msc_scsi.c. Currently untested!	9 years ago
Robert Fisk	6d7d86b2f5	Initial commit! ... Upstream (device) firmware builds, emulates a small USB block device filled with zeroes.	10 years ago
