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

Age	Commit message (Collapse)	Author
2017-10-11	Cleanup 'unused parameter' warnings, a couple of which are actual coding errors.	Paul Selkirk

2017-10-11	Cleanup: signed/unsigned mismatches, mostly in loop counters	Paul Selkirk

2017-08-31	Withdraw SysTick_hook (commit 9ffead1), because it turns out there was ↵	Paul Selkirk
	already a user-callback mechanism with HAL_SYSTICK_IRQHandler() and HAL_SYSTICK_Callback().
2017-07-31	Add a generic SysTick hook, to call a function on every 1ms tick, because ↵	Paul Selkirk
	it's easier than setting up a dedicated timer.
2017-06-17	Fix optimization settings in HSM's build of libtfm.	Rob Austein

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

2017-04-17	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.
2017-04-01	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.
2016-09-20	Still some problem with uart receive under heavy load, so change to a 2-byte ↵	Paul Selkirk
	receive buffer with half-complete callbacks, and raise the dma priority.
2016-09-01	"make clean" needs to use "rm -f" to avoid gratuitous failures.	Rob Austein

2016-07-21	Use a fresh port of libcli, which retains more of the original API.	Paul Selkirk

2016-07-06	Fix the way code is commented out, to avoid compiler warnings.	Paul Selkirk

2016-07-06	Simplify library Makefiles by using symbols defined in top-level Makefile, ↵	Paul Selkirk
	rather than re-deriving them.
2016-06-25	Split LIB*_DIR into _SRC and _BLD.	Paul Selkirk
	Also rename all instances of GNUmakefile to Makefile.
2016-06-25	Finish unwinding subrepository hairball: VPATH setup.	Rob Austein

2016-06-24	Start unwinding subrepository hairball: remove submodules.	Rob Austein

2016-06-23	Drag in libhal update.	Rob Austein

2016-06-23	Drag submodule updates into sw/stm32.	Rob Austein

2016-06-21	Update sw/stm32 to track recent subrepository commits, since without them it ↵	Rob Austein
	no longer compiles (sigh).
2016-06-14	Pull in sw/libhal CLIENT_TRANSPORT makefile fix.	Rob Austein

2016-06-14	Pull libhal changes into stm32 subrepo.	Rob Austein

2016-06-14	Bring sw/stm32 super-repository up to date with the ten zillion	Rob Austein
	commits which have been made in other repositories since the last time anybody bothered to synchronize this. Poster child for why this kind of recursive hairball belongs in release engineering rather than in source code repositories which are under active development, but that yak can wait a little while longer for its shave.
2016-06-13	Only the HSM project needs the RTOS; most of the test projects can use the ↵	Paul Selkirk
	STM32 HAL code directly.
2016-06-13	Add __end symbols for CCMRAM and SDRAM sections.	Paul Selkirk
	This lets us, say, use these sections for stack or heap.
2016-06-13	SDRAM is for uninitialized data only.	Paul Selkirk
	We don't plan to put initialized data in SDRAM, and we don't have startup code to copy initialized data, so don't even bother. Further, the linker will reserve space in FLASH, even for uninitialized data, so just don't.
2016-06-09	Put thread stack buffers in SDRAM, because pkey uses a lot of stack.	Paul Selkirk
	Also rearchitect the way we handle RPC requests - have a bunch of waiting dispatch threads rather than continually creating and deleting threads.
2016-06-07	fix some comments	Fredrik Thulin

2016-06-06	Split HAL_UART_RxCpltCallback into uart-specific callbacks.	Paul Selkirk

2016-06-06	Refactor HAL_UART_MspInit, link DMA in MX_USART*_UART_Init so ↵	Paul Selkirk
	HAL_UART_MspInit doesn't have to.
2016-06-06	Fix UART pin assignments. (It uses the Alternate in any case.)	Paul Selkirk

2016-06-06	Fix definition of LED_RED in mbed_die.	Paul Selkirk

2016-06-02	Use DMA for UART RX instead of interrupts.	Fredrik Thulin
	DMA is more efficient and less prone to miss characters than interrupts. An open question is if circular mode is really the best. If someone copy-pastes more than the RX buffer size of configuration into the CLI, we risk the DMA controller catching up with the reader and overwriting data not yet read. Since we don't have flow control back to the users terminal, we will always fail if too much data is entered before we can process it. The question is if failing to stuff new data at the end of a buffer might be better than data being overwritten - thus messing up the commands in unpredictable ways.
2016-06-01	Implement circular buffer UART RX using interrupts.	Fredrik Thulin

2016-05-26	Implement a bootloader.	Fredrik Thulin
	This bootloader is now the application at 0x08000000 (FLASH start), which the STM32 will execute upon reset. The other applications are now loaded at 0x08030000 (128 KB into the flash) and will never get started unless the bootloader has been programmed into flash too.
2016-05-25	More DFU code. This might actually work.	Fredrik Thulin
	The applications to be uploaded using 'dfu upload' have to have another FLASH defined in their linker script. Have to recompile some firmware tomorrow and test if this actually works.
2016-05-25	remove non-free files we're not using anyways	Fredrik Thulin

2016-05-24	non-working code to upload an application and jump to it	Fredrik Thulin
	Committing my work in progress in case someone else wants to help.
2016-05-23	SDRAM initialization and test code from Pavel.	Fredrik Thulin
	Integrated into the cli-test program as such: cryptech> test sdram Initializing SDRAM Starting SDRAM test (n = 0) Run sequential write-then-read test for the first chip Run random write-then-read test for the first chip Run sequential write-then-read test for the second chip Run random write-then-read test for the second chip Run interleaved write-then-read test for both chips at once SDRAM test (n = 0) completed SDRAM test completed successfully cryptech>
2016-05-23	commit bugfix from Pavel fixing initialization of the second SDRAM chip	Fredrik Thulin

2016-05-21	Add code to access the keystore memory (SPI flash).	Fredrik Thulin

2016-05-18	Add FPGA bitstream upload command to cli-test.	Fredrik Thulin
	This code needs more error checking etc. but together with the Python script 'filetransfer', a new bitstream may be loaded into the FPGA config memory like this: filetransfer --fpga /path/to/bitstream The bitstream is identified by 'file' e.g. like this: alpha_test_top.bit: Xilinx BIT data - from alpha_test_top.ncd;UserID=0xFFFFFFFF - for 7a200tfbg484 - built 2016/05/12(13:59:24) - data length 0xe0164
2016-05-18	FPGA config memory access code from Pavel.	Fredrik Thulin

2016-05-18	build libcli	Paul Selkirk

2016-05-16	Add code to talk with the external RTC chip.	Fredrik Thulin

2016-05-12	Add build target for the alpha	Fredrik Thulin

2016-04-24	This time for sure - async receive, and everything that flows from that.	Paul Selkirk

2016-04-14	import mbed rtos library	Paul Selkirk

2016-04-11	Reorganize Makefile and directory structure, because it's messy, and it's ↵	Paul Selkirk
	about to get messier.
