Cortex v8 architecture based devices support secure/non-secure builds.
Secure build should generate the object file/library from elf during link
process which is used by non-secure binary during linking.
--out-implib=file specifies output library in which symbols are exported
--cmse-implib requests libraries mentioned above are secure gateway
libraries
Creation of secure library is done as part of linking process in GCC/ARMC6/IAR
Non-Secure project should add this secure object file as part of the
linking process.
Secure library is named as cmse_lib.o.
The introduction of pretty-bar had broken the handling of
"mbed compile"'s "--stats-depth" argument. No matter what one gave
as parameter to it, the result output is just using the default 2.
Fix the logic in build_api.
LoRaMacChannelPlan class provides APIs which are not usable for
PHY layer implementations who do not support custom channel plans.
So we had some code in APIs which was explicitely using magic numbers
for the channel mask. Although it turned out to be not a bug as a layer
down we were checking for custom channel support. However, we now
check for custom channel support before going deep into PHY layer that will
make the code run faster and we have done some cosmetics to the code for
readability.
Channel mask is manipulated with inline methods
The features/mbedtls/targets/TARGET_STM/* files include constant needed
for the error codes returned from the MD functions.
The features/mbedtls/targets/hash_wrappers.c provides thin redirection
layer for the hardware accelerated MD implementations that rely on the
old API.
The TESTS/mbedtls/multi/main.cpp has been changed to use the new API
as its build environment does not rely on the translation unit
containing the necessary wrappers.
Regression after ChanFS update: Due to parameter changes in the f_mkfs
function, the option to use a separate block for MBR (FDISK) was turned
back on. This should be off as it conflicts with an explicit MBR when
using the MBRBlockDevice.
Default value for timer/idle thread trustzone identifier is 0, updated
it to 1 to allow threads to access secure functions when timer is secure device.
The PHY layer had a lot of duplicated code in various geographic regions.
In this commit we have tried to concentrate all common functionaliy into
one single class which LoRaPHY that provides three kind of methods:
i) Non virtual base methods which are there for upper layer use, e.g.,
providing access to driver or generic PHY layer functionality which
needs to be exposed to upper layers.
ii) Virtual methods (no hard limit on implementation) that can be overriden
in derived classes. Some PHY implementations will need that as they may
come with very peculiar channel schemes, e.g., dynamic channel schemes
in US bands.
iii) Protected methods which are only available for the derived PHYs
We have adopted a mechanism for the dervied PHYs to announce their differenmtiating
parameters in their constructors by filling up a data structure known as lora_phy_params_t
which exists at base level. Access modifier for this data structure is protected so it can only be
used by the base or derived classes, i.e., no exposure to upper layers.
For extra functionality and differentiating controls, a derived PHY can override any virual method as necessary.
In addition to that we have adopted the Mbed-OS style guide and have changed data structures and code to reflect that.
Some data structures are removed.
* Algorithm to get alternate DR is modified. Current scheme, works as multiples of 6 as EU and EU like PHYs
provide 6 datarates. We make sure that we try a datarate at least once. If nuber of join retries is a multiple
of 6, we may try multiple times on each data rate.
* Most of the PHYs with dynamic channel plans, always override the above mentioned algorithm as the rules governing
this algorithm do not hild in their case.
* band_t data structure is enhanced with lower band frequency and higher band frequency. That enables us to validate
frequency based upon the band and hence we can have a single function for all PHYs to validate frequency.
* In some PHYs, there were some extra channel masks were defined which were not being used. Hence removed.
* EIRP table corrected in some PHYs based upon spec.
* PHY functions in response to Mac commands are renamed to reflect what they exactly do.
for example accept_rx_param_setup_req() because that's what they do. they can either accept
the mac command or reject it.# Please enter the commit message for your changes.
This commit also introduces API change for disconnect(). disconnect() will
now return LORAWAN_STATUS_DEVICE_OFF for successfull disconnect.
* LoRaWANStack::handle_tx() can be called with NULL buffer when length is 0.
This commit fixes the case where user has provided NULL buffer and length
is > max_possible_size.
handle_tx() now always returns LORAWAN_STATUS_PARAMETER_INVALID if given
buffer is NULL pointer and length > 0.
General error checking is added and some asserts are added for events.
