Module to lock the shell after a given timeout of time x. When the
shell did not receive any input within time x, then the shell is
locked automatically.
When `MOST_RECENT_PORT` is set to `1`, the most recently added USB
serial is selected. This is a crude but surprisingly effective filter.
However, for the CC2560-Launchpad this doesn't work, as it provides
two USB serials. The first USB serial interface is the targeted UART
bridge and the second controls the debugger. Since the second is added
a tiny fraction after the first, this reliably selects the wrong
interface. Allowing the board to filter USB serials first can avoid
this issue.
This is also useful as e.g. an STM Nucleo board can easily be told
apart from an `samr21-xpro` or an nRF52840dk using such filters.
DEFAULT_MODULEs declared in defaultmodules_regular.inc.mk MAY only be
disabled at APPLICATION level or in BOARD/CPU Makefile.default. These
modules MAY have complex dependencies themselfs.
DEFAULT_MODULEs declared in defaultmodules_no_recursive_deps.inc.mk MAY be disabled
during dependency resolution. The MUST only have dependencies against
modules with no dependencies themselfs, and these dependencies must
be defined in makefiles/defaultmodules._deps.inc.mk
I think the intention was that SUIT_VENDOR_DOMAIN gets set to
$(SUIT_VENDOR) so it can be overwritten by the build system.
However, no such code was in place yet.
Individual files need to be converted to uf2 format, targets
flashing individual slots or the bootloader will work:
- riotboot/flash-slot%
- riotboot/flash-bootloader
'flash' also works by flashing both the bootloader and slot0
independently.
But not targets flashing combined/extended versions since conversion
of the blob is not possible with the uf2conv.py script.
When doing a `make debug` on a board with riotboot bootloader, the original
(non-offset) elf file gets selected.
This causes all ROM addresses to be at the wrong offset, leading to strange
debug behavior.
Set `DEBUG_ELFFILE` to the .elf file that already accounts for the bootloader
offset so the debugger gets the correct addresses.
Use -misa-spec=2.2 on newer toolchains, which allows passing the same
-march value to both the linker and the compiler even when binutils and
GCC support difference ISA specs.
This is intended for the bootloader module where we don't enter thread
mode, so mutex must never attempt to switch context.
Instead use a simple busy wait that is enough to make the possible mutex
users (e.g. interrupt based SPI) in bootloader mode work.
- move all generated manifests under $(BINDIR)/suit_files (this can be
overwritten.
- rename signed manifests so that they are of the form:
<somename>.<version>.bin, where <somename> is by default riot.suit.
This avoids cluterring BINDIR while as well having a naming scheme that
allows custom names for manifests addresssing different types of
payloads.
- rename riotboot files so that they are of the form: slot<n>.<version>.bin
- move all generated files under $(BINDIR)/riotboot_files (this can be
overwritten.
This adds:
* SUIT_MANIFEST_BASENAME: allow for non slotfiles payloads to have
different names that slotfiles payloads.
* SUIT_MANIFEST_PAYLOADS: firmware payloads to be published with the
manifest.
* SUIT_MANIFEST_SLOTFILES: firmware payloads referenced by the manifest
in the form 'filename:[offset]:[comp_name]' as expected by
gen_manifest.py.
With this the same recipes suit/publish suit/notify can be used with
non slotfiles payloads.
A backward incompatible change in the RISC-V resulting in instructions
previously included by rv32imac to only be available with
rv32imac_zicsr. All RISC-V CPUs supported by RIOT are hence either
considered as rv32imac (from the old ISA spec point of view) or as
rv32imac_zicsr (from the new ISA spec point of view). This adds a
simple test if GCC understands rv32imac_zicsr and uses it then as march,
but uses rv32imac as march if not.
This flag disables all builtin functions provided by the compiler as
well as disabling all optimizations and error checking related to
standard C library functions. If you're using a C library which
conforms to the ANSI C standard, you want to leave these compiler
features enabled.
