sw/stm32 - Cryptech HSM on STM-32 ARM processor

Age	Commit message (Collapse)	Author
2017-05-06	Correct offset to get the PC.	Paul Selkirk
	A previous version of this code ran over the RTOS, where threads used the Process Stack, while the SysTick interrupt used the Main Stack. Now everything's on the main stack, so we need to account for 2 extra words that SysTick_Handler pushes on the stack at entry.
2017-05-05	Port profiling code, using a new SysTick hook and new CLI commands.	Paul Selkirk

2017-05-04	Copy profiling code from MCUOnEclipse.	Paul Selkirk

2017-05-03	Add some task metrics.	Paul Selkirk

2017-05-02	Merge branch 'init_cleanup' into no-rtos	Paul Selkirk
	Clean up Makefiles and initialization code.
2017-05-01	Remove bogus counting-loop version of HAL_Delay.	Paul Selkirk

2017-05-01	Add HAL_Delay as an alias for task_delay, but don't wedge if the tasker ↵	Paul Selkirk
	isn't running yet.
2017-05-01	Addendum to commit e0e97a5: Remove all references to the tasker from cli-test.	Paul Selkirk

2017-04-30	Need stdint.h if we're going to use uint32_t.	Rob Austein

2017-04-30	Merge branch 'ksng' into no-rtos	Rob Austein
	Required minor manual intervention to resolve merge issues git had no way of understanding: git is clever, but not quite clever enough to understand that a commit in branch had removed the entire RTOS that a commit in the other branch was using. No big deal, just a couple of osDelay() calls needing conversion to HAL_Delay() or task_delay().
2017-04-29	Add minimal mutexes to the minimal tasking system	Paul Selkirk

2017-04-29	cli-test doesn't use the tasker, even though it might have previously used a ↵	Paul Selkirk
	semaphore from the rtos
2017-04-29	Add task_delay.	Paul Selkirk

2017-04-29	Simplify hsm makefile.	Paul Selkirk

2017-04-29	Port cli-test to the new task API.	Paul Selkirk

2017-04-29	Remove exception handlders that I probably shouldn't have defined in the ↵	Paul Selkirk
	first place.
2017-04-29	Remove rtos source files.	Paul Selkirk

2017-04-27	Replace the RTOS with a simple cooperative tasker.	Paul Selkirk
	There are no priorities and no preemption, so tasks run in a round-robin fashion, and explicitly yield control.
2017-04-27	Refactor cryptech_upload to work either directly or via cryptech_muxd.	Rob Austein

2017-04-26	Add support for hal_sleep().	Rob Austein

2017-04-17	Rewrite the wait-for-ready loop in uart_send_bytes() to actually work.	Paul Selkirk

2017-04-17	Add a short delay to osMailAlloc, since we're no longer calling it in an ISR.	Paul Selkirk

2017-04-17	Use default SysTick interrupt priority.	Paul Selkirk
	We really don't want SysTick_Handler, which runs the task scheduler, to run at a higher priority than SVC_Handler, which runs supposedly-atomic operations like mutex locking and unlocking. I've seen a mutex lock/unlock mismatch which I think is due to interrupting rt_mut_release at a particularly inopportune moment.
2017-04-17	Merge remote-tracking branch 'origin/uart_rx_thread' into ksng	Paul Selkirk

2017-04-16	Switch to libhal's CRC-32 code.	Rob Austein

2017-04-15	Missing include files, doh.	Rob Austein

2017-04-15	sw/stm32 Makefiles are a mess.	Rob Austein
	Apparently it's easier to duplicate source files into multiple project directories than to write Makefiles that do something sane. Feh.
2017-04-15	Move hal_log() support to separate module.	Rob Austein

2017-04-15	Logging implementation for Alpha hardware.	Rob Austein

2017-04-12	Handle race condition while fetching key metadata for display.	Rob Austein
	Fetching a list of keys and all of their metadata isn't an atomic process, nor, probably, should it be, so we need to cope with things like a key being deleted via the RPC interface while we're fetching its metadata for display on the console interface.
2017-04-11	Track API changes on sw/libhal pkcs8 branch.	Rob Austein

2017-04-01	Change RPC UART to have a high-priority thread monitoring a large(ish) DMA	Paul Selkirk
	buffer, because we've observed out-of-order receives under load.
2017-03-02	Try to be a bit more robust in the face of normal errors.	Paul Selkirk
	If hal_rpc_server_dispatch() returns an XDR decode error because the request packet was too short, don't call Error_Handler() and kill the dispatch thread, just drop the request. Add more ibuf_queue entries, but don't panic and kill the dispatch thread if we can't get one, just drop the incoming character (which will lead to an XDR decode error if/when we finally get an ibuf).
2017-02-23	Add --pin and --quiet options.	Paul Selkirk

2017-02-23	Speed up file upload enormously.	Paul Selkirk
	We need to start with a long serial timeout, in order to catch the reboot messages for a firmware upload (this has to be done through the bootloader). But once we start sending the file, cut the serial timeout to 1ms. (I've tested it down to 1us, but that may not work for everyone, and it doesn't improve performance in a statistically significant way.) This brings the time to upload a 4.5MB bitstream from 38:23 to 1:25.
2017-02-22	Refactor flash code.	Paul Selkirk

2017-02-21	Use libcli return codes where appropriate; show whether PINs are set.	Paul Selkirk

2017-02-21	Use bulk erase in the one place it makes sense.	Paul Selkirk

2017-02-20	Move dangerous auto_erase functionality to where it's actually used.	Paul Selkirk

2017-02-19	Remove unnecessary delays in flash code.	Paul Selkirk

2017-02-19	Simplify spiflash test code slightly, add keystore test code.	Paul Selkirk

2017-02-15	Add performance tests for spiflash_n25q128.c	Paul Selkirk

2017-02-15	Add n25q128_erase_bulk	Paul Selkirk

2017-02-02	Add locking around keystore operations.	Rob Austein

2016-12-23	Don't wrap key number in "keystore show keys".	Rob Austein

2016-12-21	Initialize PINs before trying to use them in bootloader.	Rob Austein

2016-12-21	Rewrite core upload loop to simplify and fix race conditions.	Rob Austein
	The main loop in cryptech_upload:send_file() was much more complicated than necessary, and also contained some hidden assumptions about serial I/O timing which happened to fail on the first two machines I tested. We already had a perfectly good buffered-input function, so rewrote to use that, and simplified control structure in the process. In theory, the new code should work in any environment where the old one did, but this has not yet been confirmed.
2016-12-20	Flush output to serial device after writing.	Rob Austein

2016-12-20	Merge branch 'master' into ksng	Rob Austein
	Bootloader DFU fixes.
2016-12-20	Make stm_flash_sector_num a little more efficient.	Paul Selkirk
