The test case which checks full range cannot be executed at the moment due to a hardware bug in FPGA-Test-Shield.
This test case will be restored when the final version of FPGA-Test-Shield is ready.
In Mbed OS, there are configuration options with Mbed TLS that we
are more comfortable allowing than we do with Mbed TLS on its own.
Add a check-config adjusting script to enable removing or changing
options in check_config.h
For L0/L4/H7/F7/WB targets that have tickless enabled, remove the tickless from
us ticker and the delay ticks as the C++ wrapper layer is being removed
and replaced by the low layer handling.
For now, the few F4 targets with LPTIM are left with previous configuration
as test results are showing a few instabilities not yet understood.
LP TICKER mbed-os wrapper needs to be disabled as it introduces too much latencies.
LP TICKER wrapper has been disabled and we need to managed the HW constraints at low level:
- main HW constraint is that once the comparator has been programmed once,
driver cannot program it again before CMPOK HW flag is set, which takes about 3 30us cycles.
To make it even more complex, the driver also needs to cope with "LP ticker workaround"
See commit:
LP ticker workaround
There is an errata in LPTIM specification that explains that CMP Flag
condition is not an exact match (COUNTER = MATCH) but rather a
comparison (COUNTER >= MATCH).
Also the disable interrupt is more complete now:
- always check sleep manager status and restore it
- remove irq_handler as comparator is always programed and might get called
eventually when LP TICK is restarted
- reset delayed_prog
Also in set_interrupt, make sure interrupt does not fire early.
If needed, we decide to slightly delay the tick to cope with the HW limitation to
make sure it will fire as soon as HW is capable.
Functions are called under critical section as they may be called from
the IRQ handler now, not only from driver layer.
There is an errata in LPTIM specification that explains that CMP Flag
condition is not an exact match (COUNTER = MATCH) but rather a
comparison (COUNTER >= MATCH).
As a consequence the interrupt is firing early than expected when
programing a timestamp after the 0xFFFF wrap-around.
In order to
work-around this issue, we implement the below work-around.
In case timestamp is after the work-around, let's decide to program the
CMP value to 0xFFFF, which is the wrap-around value. There would anyway be
a wake-up at the time of wrap-around to let the OS update the system time.
When the wrap-around interrupt happen, OS will check the current time and
program again the timestamp to the proper value.
In rtos/mbed_lib.json:
Enlarge idle-thread-stack-size-debug-extra for all Nuvoton targets.
In rtos/TARGET_CORTEX/mbed_rtx_conf.h:
MBED_DEBUG also must be defined for this configuration parameter to take effect.
The file 'fsl_powerquad_data.h' declares several dctXXX_cosFactor
arrays with sizes twice larger compared to the actual definitions in
'fsl_powerquad_data.c'.
Fixes#9744
Appears to be a lwIP porting bug. Comments in our porting layer say:
This function should support recursive calls from the same task or interrupt. In other words, sys_arch_protect() could be called while already protected.
If "lwip.tcp-enabled" is set to false, ARMC6 compilation fails to error
Error: L6218E: Undefined symbol netconn_recv_tcp_pbuf
LWIP::socket_recv() is TCP socket specific method so implementation can be
enabled only when LWIP_TCP flag is set.
Static keyword causes problems when trying to use force-inlined
functions from normal inlined functions. This is not legal:
static inline void forced() { }
inline void normal() { forced(); }
You cannot reference internal-linkage things from external-linkage
inline functions.
Removal of the static implies that in C there would need to be a
non-inline definition in case anyone calls it non-inlined, but if the
force attribute is doing its job, that should not happen.
Only significant in-tree user of the MBED_FORCEINLINE macro is
the atomic operations - making this change permits atomic operations
from non-static inline functions.
Use `+ 1` to set the "Thumb" indicator on the `delay_loop` routine
address, rather than `| 1`. That makes it something that can be done
by the linker, rather than needing to be done at run-time.
Saves one instruction and one cycle.
