Hooking into the existing wrappers for `malloc()`, `calloc()`,
`realloc()`, and `free()`, the new (pseudo) module `malloc_tracing`
prints out the calls to the given functions, the program counter of
the caller, as well as the return result.
The intent is to aid debugging double-frees, invalid frees, or memory
leaks.
Modern binutils complain about segments with RWX permissions. While
this is indeed a bad habit, RIOT ignores segments permissions anyway.
(We do have a `mpu_noexec_ram` module to disable execution of all of
RAM, which would do so regardless of the segment permission.) So for
now, we can safely just disable the warning.
This fixes:
/usr/lib/gcc/arm-none-eabi/12.2.0/../../../../arm-none-eabi/bin/ld: warning: /home/maribu/Repos/software/RIOT/examples/default/bin/nucleo-f767zi/default.elf has a LOAD segment with RWX permissions
collect2: error: ld returned 1 exit status
The test for the requirement of disabling wchar_t size warnings assumed
that $(CC) is used for linking, instead of $(LINK). With GCC $(LINK)
and $(CC) happen to be (in most cases) identical, but with LLVM they
are not. This results in issues with compiling with LLVM.
GCC on some platforms does need an executable stack to generate
trampoline code, but use of nested functions is not allowed in
RIOT's code base anyway.
This allows including C headers from C++. It sadly reduced the
diagnostics on C++ code as well, were there warning may make sense as
unintended side effect. We may be able to drop that later on, when more
C APIs are properly wrapped in native C++ APIs, so that C headers do no
longer need to be compatible with C++ compilers.
In an ideal world everyone would just install `gdb-multiarch` and be
happy. However, some MCUs need magic GDB versions sprinkled with
unicorn-stardust-Espressif-patches...
Since there is little reason to have `$(target)-gdb` installed in
addition to `gdb-multiarch` if `gdb-multiarch` would work fine, let's
assume the user wants to use `$(target)-gdb` when present over
`gdb-multiarch`.

Add USE_MODULE += "stdio_uart_onlcr" to enable it.
This is named after the "onlcr" stty flag, which does the same thing.

Model the LoRaWAN integration to GNRC's netif command (ifconfig) as
submodule of it, namely `shell_cmd_gnrc_netif_lorawan`.
This should fix a regression introduced by
https://github.com/RIOT-OS/RIOT/pull/18355
When using podman instead of docker the registry is not set by default.
Docker has a builtin registry default "docker.io". Podman does not have a
default. By specifying the registry explicitly both tools can be used.
With RISC-V being a relatively young toolchain, a lot of inconsistencies
between different toolchains are to be found that differ in the target
triple and the flags supported. This build system performs run-time
tests to detect the toolchain and supported flags.
With `BUILD_IN_DOCKER=1` issues arise, as this checks are performed
outside of the docker container. However, the host may have no RISC-V
toolchain installed or a different toolchain, so there is little reason
in performing this detection then. Instead, a hard coded target triple
and supported flags are provided when using `BUILD_IN_DOCKER=1`.
If `AVRDUDE_PROGRAMMER` is already set to a programmer that is also
capable of debugging, we can assume that typically the user will want
to use the same hardware for debugging. Thus, let `AVR_DEBUGDEVICE`
default to the matching hardware.
`tiny_strerror()` is a drop-in replacement for `strerror()`, but
instead of a long help message it returns the much shorter macro name
matching the given number.
The (pseudo-)module `tiny_strerror_as_strerror` can be used to
replace all calls to `strerror()` with calls to `tiny_strerror()`.
Previously `shell_commands` was a "catch-all" module that included
shell commands for each and every used module that has a shell
companion. Instead, the new `shell_cmds` module is now used to provide
shell commands as individually selectable submodules, e.g.
`cmd_gnrc_icmpv6_echo` now provides the ICMPv6 echo command (a.k.a.
ping).
To still have a "catch all" module to pull in shell commands of modules
already used, `shell_cmds_default` was introduced. `shell_commands`
depends now on `shell_cmds_default` for backward compatibility, but
has been deprecated. New apps should use `shell_cmds_default`
instead.
For a handful of shell commands individual selection was already
possible. Those modules now depend on the corresponding `cmd_%` module
and they have been deprecated.
Add tracing support via GPIOs to trace the basic state of the Ethernet
peripheral. The following signals are provided:
- One GPIO pin is toggled on entry of the Ethernet ISR
- On TX start an GPIO is set, on TX completion it is cleared
- On RX complete an GPIO is set, once this is passed to the upper layer
the GPIO is cleared again
In order to reduce the overhead, GPIO LL is used. By default the
on-board LEDs are used as tracing GPIOs. This makes it easy to debug
when the state machine gets stuck without the need to attach a scope or
logic analyzer.
JLink presumably has information about the device's RAM available
internally. Not passing the precise symbol area (which would be
available in the ELF file) because a) that'd make the terminal break
when the flashed firmware does not equal the built one, and b) that
would introduce a dependency from `term` to the ELF file that other
terminals don't have.
When `stdio_cdc_acm` is used, assume `"RIOT-os\.org"` as vendor string
and `$(BOARD)` being used as model string. This is the default
behavior in RIOT since eaace28804
After introducing #18423 there are occasional messages that still happen.
These messages cause a diff output when testing with TEST_KCONFIG=1.
This then causes a failure when comparing make/kconfig modules and packages.
A if `netdev_driver_t::confirm_send()` is provided, it provides the
new netdev API. However, detecting the API at runtime and handling
both API styles comes at a cost. This can be optimized in case only
new or only old style netdevs are in use.
To do so, this adds the pseudo modules `netdev_legacy_api` and
`netdev_new_api`. As right now no netdev actually implements the new
API, all netdevs pull in `netdev_legacy_api`. If `netdev_legacy_api` is
in used but `netdev_new_api` is not, we can safely assume at compile
time that only legacy netdevs are in use. Similar, if only
`netdev_new_api` is used, only support for the new API is needed. Only
when both are in use, run time checks are needed.
This provides two helper function to check for a netif if the
corresponding netdev implements the old or the new API. (With one
being the inverse of the other.) They are suitable for constant folding
when only new or only legacy devices are in use. Consequently, dead
branches should be eliminated by the optimizer.
Allow issuing a reset to bootloader sequence by abusing the RTS and
the DTR pins of a TTL adapter. This makes flashing via UART much
more convenient, as no jumpers need to be placed to select booting to
the bootloader / flash and no reset buttons need to be pressed.
If Quad SPI modes qout or qio are set by variable FLASH_MODE, esptool.py has to be called with parameter `--flash_mode dio` so that the first stage bootloader is always using Dual SPI mode.
Examples have previously relied on the (really: some) nightly toolchain
to be the default. As that, in practice, is a problematic assumption,
the latest toolchain to use is now determined programmatically, and that
is set explicitly on the examples that use nightly.
Workaround-For: https://github.com/rust-lang/rustup/issues/3015
Let's consider firmwares as identical if their flash files are matching.
This will have the side effect that hash mismatches for ESP32 due to
different .debug sections in the ELFFILE are prevented, as for ESP32
the BINFILE is used.
This is also a workaround for Rust's [97685], but primarily to enhance
the error message by pointing out that -Zbuild-std is an option, and
generally presenting the error as RIOT usually does.

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.
Placing the SUIT key in the RIOT repository folder is dangerous as
a repo checkout is by most people considered a volatile location.
Since all important files are stored in git, deleting the entire folder
or it's contents is not an uncommon cleanup operation.
If the user is at that point unaware that SUIT key material is stored
in that folder, that key will then be lost.
Another workflow may involve multiple checkouts of the RIOT repository
to multiple folders to work on several features at the same time, or for
easy cross-referencing or splitting of off features from an integration
into a feature branch.
In that case each checkout would use it's own incompatible SUIT key.
To avoid all these pitfalls, place the SUIT keys outside the RIOT
repository in the $XDG_DATA_HOME directory.
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.
