Add a trivial shell program that scans for all slaves on an I2C bus by iterating
all of the possible 127 I2C addresses and checking for the ACK of the device.
The build system contains several instances of
INCLUDES += -I$(RIOTBASE)/sys/posix/include
This is bypassing the module management system, by directly accesing
headers without depending on a module. The module is the posix module.
That line is also added when one of the posix_* modules is requested.
According to the docs, the posix module provides headers only, but in
reality there is also inet.c.
This patch:
- Moves `inet.c` into `posix_inet`, leaving `posix` as a headers-only
module.
- Rename `posix` as `posix_headers` to make it clear the module only
includes headers.
- Makes `posix_*` modules depend on `posix_headers`, thus removing the
explicit `INCLUDES+=...` in `sys/Makefile.include`.
- Ocurrences of `INCLUDES+=...` are replaced by an explicit dependency
on `posix_headers`.
In UniFlash 4.4.0 the directory where 'xds110reset' is changed.
Try to use the newest one available. If none is found in UNIFLASH_PATH,
try to use one from the PATH to be sure to have a value.
./uniflash_4.1/simplelink/gen2/bin/xds110reset
./uniflash_4.3.0/simplelink/gen2/bin/xds110reset

Linkerscript for `nrf52dk` has been updated to use `cortexm.ld` so does
not need the configuration anymore for the removed
`cpu/nrf52/ldscripts/nrf52832xxaa.ld`.
JLink flasher used by the only supported board `nrf52dk` has been updated.
FLASHFILE must now be defined by the board to use this in case a new one
wants to be supported.
Refactor to define REALMODULES incrementally without overwriting
'NO_PSEUDOMODULES'.
This also allows an external makefile to maybe add something there if it really
needs to.
Factorize the reused value in a private variable.
I define it private as somehow 'USEPKG' is supposed to be removed so the
variables can be removed later.
BASELIBS is used only in the main Makefile.include or included files.
As it is not used in sub make executions or scripts it does not need to
be exported.
The canned recipe is preferred to using $(FLASHER) $(FFLAGS) as it
allows to specify additional action actions (like what preflash is
currently doing.)
A canned recipe had previously been defined to perform the flashing
procedure. The canned recipe is preferred to calling $(FLASHER) $(FFLAGS)
as there might be additional steps involved in flashing (this is handled by
preflash currently but with the canned recipe we will be able to fix it.)
Modern versions of GDB support multiple targets with the same gdb binary.
At least Ubuntu and Debian have dropped the gdb-arm-none-eabi package in favour
of gdb-multiarch.
Here, no $(PREFIX)-gdb binary is availiable, instead gdb-multiarch should be used.
This patch tries to automatically detect the presense of gdb-multiarch and uses it
instead of arm-none-eabi-gdb.
Using 'link' was working too but will introduce a circular dependency
when FLASHFILE is one of the slot files.
This trims down to the minimal required dependency to work. It is now
the same as `ELFFILE` dependencies.
If FLASHFILE is set keep the original value.
It changes the variable from an immediate to a deferred variable but if
murdocks keeps working there is no issue.
