Expose the auto-negotiation feature of the Ethernet device via the
pseudo-module stm32_eth_auto. With this enabled, the static speed configuration
set in the boards periph_conf.h will only be used if the PHY lacks
auto-negotiation capabilities - which is unlikely to ever happen.
This feature is only used to blacklist stdio via CDC ACM.
Introduce the `highlevel_stdio` feature instead to indicate
that stdio functionality requires a running thread to print
anything
This adds a check in the build process to verify that no ERROR_ Kconfig
symbols are set. These symbols indicate invalid conditions in the
Kconfig configuration.
This commit introduces a common storage backend for SUIT manifest
payloads. Different backends can be compiled into a single firmware.
Degending on the component name in the SUIT manifest, a storage backend
is selected by the parser.
- Set XTIMER_HZ to something that is actually possible to generate with one
of the available clock dividers from the core frequency
- Use xtimer_on_ztimer if xtimer is used and not ztimer_xtimer_compat is used
- This is needed because xtimer is simply not compatible with any of the
possible clock frequencies of this board
Kconfig.dep depends on FORCE, so it is always generated when compiling
with Kconfig under normal conditions. Whan TEST_KCONFIG=1 is set, this
file is no longer a dependency for out.config. So when cleaning the
'bin' directory, out.config has no direct dependencies that force its
rebuilding (the generated directory is order only). This causes the file
not to be produced when calling `TEST_KCONFIG=1 make clean all`.
This PR changes the dependency on the 'generated' directory to a direct
dependency when `CLEAN` is set and leaves it as order-only when not.
This allows to generate out.config only when needed by not depending on
FORCE.
Use riscv-none-elf instead of legacy riscv-none-embed as target triplet for
RISC-V development. However, if ricsv-none-elf is not present, try
riscv64-unknown-elf and riscv-none-embed instead. If the legacy riscv-none-embed
is used, a warning is printed.
Add `TARGET_ARCH_<ARCH>` for each architecture (e.g. `TARGET_ARCH_CORTEX` for
Cortex M) to allow users to overwrite the target triple for a specific arch
from ~/.profile or ~/.bashrc (or the like) without overwriting it for all others
as well.
It has no real purpose other than pulling in `gnrc_ipv6_router` as a
dependency, which is already done in other places (or by pulling in its
dependencies).
CDC ACM, ethos, Semihosting and SLIP all benefit from sending data out
in larger chunks and will benefit from stdout buffering.
`stdio_rtt` does have an internal TX buffer, so we don't need to do any
buffering on top.
With plain UART there was a slight advantage *without* buffering when
testing with `tests/periph_uart_nonblocking` (with the non-blocking feature
disabled).
Since the removal of the buffering saves us some RAM and ROM, disable it by
default there.
This will be different with DMA enabled UARTs.
