Found and fixed the issue for the kinetis-based boards: The kinetis
code is using some macros to map some IRQ names, that differ in
some versions of vendor headers, to a RIOT wide unique name. The
doxygen of this mapping states, that this mapping must be done before
any vendor header is included. Unfortunately, the mapping was so far
placed in cpu/kinetis/vectors.c, before any other include statement.
In some cases, the vendor headers might be included before the
mapping macros in vectors.c, leading to the compilation errors down
the line. To fix this, the adaption defines are moved into
cpu/kinetis/cpu_conf.h, which is the file that actually includes
the vendor headers. This way it is ensured, that these adaption
macros are always defined before any vendor header is included,
and therefore preventing this kind of error for good.
If there is an event to be handled by _esp_eth_isr(), don't
overwrite it if a new packet has been received.
In my testing, all SYSTEM_EVENT_ETH_CONNECTED events except the first
are immediately followed by at least one SYSTEM_EVENT_ETH_RX_DONE event.
This causes the SYSTEM_EVENT_ETH_CONNECTED to not get handled, and the
IP stack will not be notified of the new link state.
Protect the other events by dropping the packet instead. If an earlier
unhandled SYSTEM_EVENT_ETH_RX_DONE event exists, overwrite it with the
newer packet.
I only saw this happen with lwIP and not with GNRC - I am not sure why.
But it still is a race waiting to happen. The nice long term solution
is probably to have a queue of unhandled events, allowing them all to
be processed once there is time.
The ADC SYNCBUSY.SWTRIG gets stuck to '1' after wake-up from Standby Sleep mode.
Ignore the ADC `SYNCBUSY.SWTRIG` status bit, this functionality is not used by
the driver anyway.
The global core/ldscripts/xfa.ld doesn't match our cortexm_base.ld.
This commit directly adds the two XFA lines to cortexm_base.ld.
In addition to that, a dummy (empty) xfa.ld is added, which the linker will pick
instead of core/ldscripts/xfa.ld, effectingly not using it.
nRF52833 has POWER_MAINREGSTATUS_MAINREGSTATUS_High, but no POWER->DCDCEN0
register.
This breaks all builds on this MCU.
Fix the ifdef to fix the build.
