Redirecting `2>&1 >/dev/null` moves stderr to stdout first and then
stdout to /dev/null; when checking for command existence or otherwise
silencing output, this is usually not desired (but only starts producing
errors when the actual command fails, which is often not tested).
Introduce XMEGA EBI driver. This enable EBI for use with all memory
supported by the device and peripherals. It include support to SRAM,
SDRAM, LCDs or any other external bus access.
Note: This feature only works for A1/A1U series, which are, the series
with EBI hardware.

This is a regression which was introduced in #16114, without resetting
the color the red color will be used for all following text written to
the terminal and will also cause the shell prompt etc. pp. to be colored
in red which is undesirable. This commit fixes this regression by using
the ANSI escape sequences to reset the color after the error message has
been written.
Prefix delegation used to be the only supported feature of our DHCPv6
client, but by now it also supports MUD, DNS recursive name servers and
IA_NA is on the horizon. So it makes sense to make IA_PD an optional
module like all those other features are as well.
The `udp` command is a valuable debugging tool that is also useful
outside of the gnrc_networking example.
To enable easy sending of udp messages in other applications during
development, move the `udp` command to the shell module and introduce
the `gnrc_udp_cmd` pseudo-module to enable it.
There is no real reason for that pseudo-module to use the `gnrc_`
prefix. Neither does it need GNRC-components (except, but optionally, as
a network stack of course), nor is it implemented with in the GNRC
network stack.
A lot of things break if `GNRC_NETIF_FLAGS_HAS_L2ADDR` is not set.
In order to handle router advertisements and auto-configureation,
generate a faux l2 address based on the netdev ID.
Previously, external modules had to be individually added to both
EXTERNAL_MODULE_DIRS and USEMODULE. If those where not in sync, this
resulted in build errors.
With this commit, search folders for external modules are added to
EXTERNAL_MODULE_DIRS instead. So lets say the file system structure is
like this
```
└── /path/to/external/modules
├── mod_a
│ ├── Makefile
│ ├── Makefile.dep
│ ├── Makefile.include
│ ├── foo.c
│ └── include
│ └── external_module.h
└── mod_b
├── Makefile
└── bar.c
```
One now adds `/path/to/external/modules` to EXTERNAL_MODULES and only
with `USEMODULE += mod_a` the corresponding module, dependencies and
include settings are actually used. Hence, it is possible to configure
`EXTERNAL_MODULE_DIRS` from `~/.profile` or `~/.bashrc` once and never
needs to worry about them again.
c_xxxx functions can be used to wrap a piece of text in a
$(COLOR_X)...$(COLOR_RESET) block, thereby avoiding the easy mistake
of forgetting to place a COLOR_RESET.
The escape codes and special chars now live in their own module. The
color module is only concerned with detecting whether to use colors or
not.
Additional variables are defined with hard a coded ESC char, a tab and a
newline. This removes the need for echo or printf.
The color strings COLOR_* are redefined so that they don't have to be
processed by "echo -e". This is done by storing the already interpreted
ANSI sequence in a shell variable.
With this change, not only can color messages be printed using normal
`echo` with no switches: colors also work with the `info` and `warning`
builtins of make.
The COLOR_ECHO variable is kept because it is also being used (confusingly)
to intepret tabs an newlines. This will be fixed in another commit.
This change should change absolutely anything and colors should still work
as always.
The partition table of the device in the esp8266 and esp32 based boards
was set to a default table with one "factory" partition with exactly
the size of the compiled firmware. This is problematic if we want to
update the device on the field.
This patch allows to set the `PARTITION_TABLE_CSV` variable from the
Makefile to a .csv file with a custom partition table, for example this
could be set to a partition table with two ota entries, or with a single
factory entry but of a known fixed size.
While nice at first, this causes more issues than it's worth for
a slightly more pretty output.
Hiding information from developers is not a good idea, especially when
it comes to an often finicky programming step.
While in theory error output should be caught, there are enough
cases where the programmer will get stuck in a loop or require user
input that hiding programmer output by default is a bad idea.
The Silicon Labs Si705x sensors (Si7050/1/3/4/5) are very similar to the
Si7021 sensors featuring only a temperature sensor and no humidity
sensor. The only difference between the Si705x is the temperature
accuracy of the reading, ranging from +/- 0.1 C in the Si7051 to +/- 1 C
in the Si7050.
This patch adds support for this family of sensors extending the
functionality of the existing si70xx driver. Following the style of
other modules, this implements a pseudomodule per supported chip, adding
si7050, si7051, si7053, si7054 and si7055 pseudomodules.
As a minor change this patch also implements the missing
si70xx_get_serial, si70xx_get_id and si70xx_get_revision functions that
were declared in the si70xx.h header but implemented as private
functions. The si70xx_get_id() may be relevant for the application to
know at run time exactly which version of the hardware is installed.
The updated test running with a Si7051 shows the following output, which
seems consistent with the room temperature conditions during the test.
```
make SI70XX_VARIANT=si7051 -C tests/driver_si70xx/ all flash
```
```

When riotboot depends on a package for building that the main
application also depends on (e.g., gecko_sdk for efm32), previously,
that package would be checked out twice in parallel, which fails.
This commit adds pkg-prepare as dependency to the bootloader target,
ensuring any packages are already up-to-date before calling the
bootloader submake.

When multiple debuggers are connected then pyocd shows an interactive
UI to select the user interface to flash, with python wrapper this
is lost.
Until a similar functionality is implemented with the wrapper disable
the programmer wrapper script when pyocd is used.
`cosy` is a graphical memory usage analyzer.
It is a great tool, but pretty hidden.
Add it as a build target so it can be easiely summoned for any application and board.
The standard is 9 years old now, it is well supported in all mayor compilers.
In fact, features of the 'new' standard are already used in RIOT (std_atomic).
Let's make it the default and adapt the Makefiles accordingly.
clang/LLVM is a bit more finicky with what target triples it accepts compared
to GCC. However, the GCC target triple is needed to properly locate the C
libraries. In case a locally installed GCC toolchain uses a technically not
fully correct target triple, it might be impossible to build with LLVM.
The solution here is to allow specifying a TARGET_ARCH_LLVM target triple
(which defaults to TARGET_ARCH), which is passed to clang. For locating the
C lib, still TARGET_ARCH is used.
FEATURES_CONFLICTING previously was declared prior to the function it is
calling, resulting in empty output during the first dependency resolution
iteration. This fixes the order so that the conflicting features are detected
right from the first recursion.
Previously, FEATURES_REQUIRED_ANY didn't honor the order of the alternatives
provided, if none of the features were already in used and multiple options
are provided. This fixes this.
RISC-V support semihosting in very similar way as the cortex-m
microcontrollers. The code calls a breakpoint instruction and the
attached debugger reads/writes registers and memory for stdio.
The RISC-V architecture doesn't support a call number with the EBREAK
instruction, to allow the debugger to detect a semihosting break point,
the EBREAK instruction is wrapped in a SLLI and SRAI instruction. These
use x0 as output register, making them NOP instructions.
One caveat when using this is that the RISC-V core traps the EBREAK
instruction with trap code 3 when no debugger is attached. Restarting
the application with the debugger attached avoids this.
These targets cannot be used in an automated testing workflow without
complex configuration or extend rights.
- Add new 'test-as-root' target for tests that require to be root or
start an external daemon as root
- Add new 'test-with-config' target for tests that require a specific
configuration to succeed (module configuration or hardware
configuration)
This commit makes overflow of signed integers to behave as expected by at 90%
of the C developers, even though overflow of signed integers are strictly
undefined behavior.
Note: Please do not add code relying on a specific behavior for the overflow of
signed integers, even though `-fwrpav` will make that code work. This is
intended to mitigate the risk of bugs in overflow checks being exploited,
not to encourage adding new bugs.
See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=30475 for details and see
http://c-faq.com/misc/intovf.html on how to implement overflow checks properly.
The driver uses the netdev interface. Due to the limited
capabilities of the transceiver (32 byte FIFO and no source address in the layer2 frame),
it relies on 6LowPAN compression and adds the source address to the frame for that.
Split out Gunar Schorcht's clever approach to provide thread safe malloc for
AVR into a system module and make AVR depend on this. This allows other
platforms to also use this.
