When flashing some applications the flasher sometimes gets stuck which
prevents flashing after.
It may be from a specific firmware or operation but do not have one yet.
Connect with reset asserted fix flashing from this state.
It was found after the `stm32f3discovery` get stuck in a non-flashable mode
after some firmwares.
- Moved compiler & linker flags from boards/common/msba2 to cpu/arm7_common
- Moved dependency to newlib nano to cpu/arm7_common
- Moved config to link in cpu/startup.o to cpu/arm7_common
Enable the handling of flashing `softdevice.hex` when flashing the firmware
for openocd.
However, for flashing, only the `hexfile` and `binfile` can currently be used.
The `elffile` is generated with local pages aligned to `0x10000` which makes
the program starting at `0x1f000` be flashed from `0x10000` with padding bytes
even if the `.text` section is indeed at `0x1f000`:
readelf --sections bin/nrf52dk/gnrc_networking.elf
...
[ 1] .text PROGBITS 0001f000 00f000 00f698 00 AX 0 0 16
...
readelf --segments bin/nrf52dk/gnrc_networking.elf
...
LOAD 0x000000 0x00010000 0x00010000 0x1e6a0 0x1e6a0 R E 0x10000
...
The padding bytes would go through `verify_image` in `openocd` so be expected
to not be overwritten but are by `softdevice.hex`
Using --nmagic at link time removes the local page alignement but would
need dedicated testing.
- The Jiminy-Mega256RFR2 is seemingly unmaintained, as no one has responded
on requests to test changes on it. This lack of support has been blocking
various PRs in the last few months
- No one seems to use it
- Boards that are added to RIOT should match at least one of the following
- It is actively maintained
- It has a significant user base
- It is an off-the-shelf product, so it might be easily obtained for testing
==> The Jiminy is matching none of the above
Use the new OPENOCD_RESET_USE_CONNECT_ASSERT_SRST to configure
'reset_config connect_assert_srst' when flashing and resetting only.
This removes the need for a special debug configuration and should allow
connecting to a running target again.
When in an invalid state, the board could not flash anymore.
Like for example after flashing `tests/driver_adt7310` this makes it
flash again.
I used `reset_config srst_only` as the other kinetis boards are also
configured that way.
- Nucleo-f091rc can become unflashable when hardfaults occure.
To make sure flashing succeeds `connect_assert_srst` is called
before connecting to flash threw openocd.
Do not set 'OPENOCD_EXTRA_INIT' but rely on
'openocd/openocd-adapters/dap.inc.mk' to select the adapter.
Using 'OPENOCD_EXTRA_INIT' for this was deprecated.
When 'DEBUG_ADAPTER_ID' was set it was already the case but not with
'SERIAL'.
The compatibility with using 'SERIAL' is maintained.
The boards are using `pyterm` specific options that do not work on any
other `RIOT_TERMINAL`. It is a shame this is required but at least do
not pass arbitrary arguments to the other RIOT_TERMINAL.
So use the new PYTERMFLAGS for this.
cpu/$(CPU)/Makefile.features and cpu/$(CPU)/Makefile.dep are
automatically included
Part of moving CPU/CPU_MODEL definition to Makefile.features to have it
available before Makefile.include.

- Removed cc110x driver
- Updated all makefiles
- Kept both board specific configurations and support for it in RIOT's
upper layers, so re-implementations don't need to start from zero
softdevice needs the memory at 0x2000 to be initialized to 0xffffffff
according to #5893 and testing. However, the addresses [0x8bc, 0x3000[ are not
set in softdevice.hex.
So use a modified hex file with all the memory set to 0xff as it is the rom
reset value anyway.
This change updates the `.hex` file instead on relying on erasing the
memory.
When running tests using 'nordic_softdevice_ble', the 'softdevice.hex'
file must also be taken into account for the test hashing and be
uploaded to the separated murdock testing boards.
When listed as dependency from `test-input-hash` the file must have a
target, which he has not. The file is implicitly created when compiling
`ELFFILE` so declare it as order only dependency.
In practice `BASELIBS` could be enough or even `pkg-build-softdevice`
but I do not want to be depend that much on internals there.
- Boards using stm32f103xx use the same custom config for xtimer
which relies on the same underlying hardware timers that hang
when sleeping for <20us so spin when approaching that limit.
A new blue pill variant with only 32 KiB of flash (secretly coming with
64 KiB flash) instead of the use 64 KiB flash (secretly coming with 128 KiB)
is not compatible with `make flash`. This commit changes the OpenOCD config
so that both variants can be flashed.
While testing the Arduino example for ESP32 boards, the problem of gpio_read for output ports was figured out. During these tests, also the wrong comment has been fixed.
- SPIM0/SPIS0/TWIM0/TWIS0 have the same priority and are mutually exclusive,
to allow concurrent use we change the default TWIM used for i2c to
TWIM1 since spi uses SPI0 by default
