Age	Commit message (Collapse)	Author
2016-06-20	Ring buffers for more reliable UART receives.	Paul Selkirk

2016-06-20	Use SDRAM for a very limited sort of heap.	Paul Selkirk

2016-06-14	Whack shell scripts to work on Debian Jessie too.	Rob Austein

2016-06-14	hsm project was failing with obscure make error because makefile did not ↵	Rob Austein
	specify dependency on libcli.
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	Track libhal RPC_MODE simplification; add bootloader to "all" target.	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.
2016-06-14	Import cli-test into hsm pretty much as-is.	Paul Selkirk

2016-06-13	Change gpio setups from macros to inline functions.	Paul Selkirk

2016-06-13	RSA keygen needs even more stack space than I thought.	Paul Selkirk
	Also, it turns out the linker wants to include initializers for sdram variables in the .elf and .bin files, even though it should handle it like bss. So now we manage sdram directly with a pseudo-malloc.
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.
2016-06-13	Hide sdram initialization functions and defines.	Paul Selkirk

2016-06-13	Use a delay loop, so sdram can be initialized from the startup code, before ↵	Paul Selkirk
	the clock is running.
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.
2016-06-09	Rename main.c to hsm.c for consistency and a slightly simpler Makefile.	Paul Selkirk

2016-06-08	Include strings.h, for strcasecmp().	Rob Austein

2016-06-08	bootloader doesn't need stm-fmc either	Fredrik Thulin

2016-06-08	Merge branch 'master' of git.cryptech.is.:sw/stm32	Fredrik Thulin

2016-06-07	Don't reboot when CLI logout is intended.	Paul Selkirk

2016-06-07	Check the HARDWARE_EARLY_DFU_JUMP flag as soon as possible in the boot process.	Paul Selkirk
	This avoids the situation where the bootloader systick happens during firmware initialization, and freaks out. Also build the bootloader with the minimum resources needed (no RTOS, no SPI, no I2C).
2016-06-07	fix some comments	Fredrik Thulin

2016-06-06	Use refactored slip/serial code.	Paul Selkirk
	Client daemon sends client ID, echo it back in response.
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

2016-06-06	Change enum stm_uart_port port to a typedef.	Paul Selkirk

2016-06-06	Restore LED definitions for dev-bridge board.	Paul Selkirk

2016-06-06	Remove the 6-second blue blink for alpha board.	Paul Selkirk

2016-06-06	Remove unused hex file.	Paul Selkirk

2016-06-06	Remove unused projects.	Paul Selkirk

2016-06-06	Don't break builds for dev-bridge board.	Paul Selkirk

2016-06-02	Merge branch 'ft-uart_it'	Fredrik Thulin

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.
2016-06-02	Move the rest of the CLI commands out of cli-test.c.	Fredrik Thulin

2016-06-01	Implement circular buffer UART RX using interrupts.	Fredrik Thulin

2016-06-01	Move FPGA related commands to mgmt-fpga.c	Fredrik Thulin

2016-06-01	Wait for FPGA_DONE on startup (available on Alpha board)	Fredrik Thulin

2016-05-31	Update huart names to reflect change in stm-uart.	Fredrik Thulin

2016-05-27	Merge branch 'ft-dfu-code-loading'	Fredrik Thulin

2016-05-27	formatting	Fredrik Thulin

2016-05-27	Merge branch 'master' of git.cryptech.is.:sw/stm32	Fredrik Thulin

2016-05-27	DFU working - but no signature validation for now.	Fredrik Thulin

2016-05-27	cli_command_root_node: bugfix missing command callback	Fredrik Thulin

2016-05-26	Figure out if the user (me) has a NUCLEO board.	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.
