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

Age	Commit message (Collapse)	Author
2021-06-28	Revert Peter's hardware flow control patch, as it sometimes causes	Paul Selkirk
	corruption on the sending side of USART2 (user/RPC) under load.
2020-10-15	Peter Stuge's fix for hardware flow control: Program CTS and RTS pins as ↵	Paul Selkirk
	alternate functions.
2017-10-17	Overhaul UART API	Paul Selkirk
	MGMT is the default UART, and no one should have to explicitly refer to the UART unless they need USER (hsm.c:hal_serial_send_char). The default UART is now exposed in the header file, so that the default-using functions can be macros, which saves a few bytes in code space, and a few microseconds in function call overhead.
2017-10-11	Cleanup 'unused parameter' warnings, a couple of which are actual coding errors.	Paul Selkirk

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

2016-07-06	Add uart_set_default() to make debugging output easier.	Paul Selkirk

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