Musca-B1 is a Cortex-M33 based target with security extension enabled.
- ARM_MUSCA_B1 is the non-secure target running mbed-os.
- ARM_MUSCA_B1_S is the secure target running TF-M.
- TF-M sources were imported and patched in previous commits.
- TF-M secure bootloader (McuBoot) for MUSCA_B1 is submitted by a
pre-built binary.
- A post-build hook concatenates The secure and non-secure binaries,
signs it and then concatenates the bootloader with the signed binary.

Support secure/non-secure combined build for non-PSA target:
1. In secure post-build, deliver built secure image to TARGET_NU_PREBUILD_SECURE
directory which is to combine later.
2. In non-secure post-build, merge non-secure image with secure image saved in
TARGET_NU_PREBUILD_SECURE directory.
3. In non-secure post-build, user can also drop pre-built secure image saved in
TARGET_NU_PREBUILD_SECURE directory and provide its own by adding the line below
in mbed_app.json:
"target.extra_labels_remove": ["NU_PREBUILD_SECURE"]
Musca-A1 is a Cortex-M33 based target with security extension enabled.
- ARM_MUSCA_A1 is the non-secure target running mbed-os.
- ARM_MUSCA_A1_S is the secure target running TF-M.
- TF-M sources were imported and patched in previous commits.
- TF-M secure bootloader (McuBoot) for MUSCA_A1 is submitted by a pre-built binary.
- A post-build hook concatenates The secure and non-secure binaries,
signs it and then concatenates the bootloader with the signed binary.
Change the heuristic for selection of CMSE in the tools python, so that
a non-TrustZone ARMv8 build can happen.
Ideally we would have more direct flagging in the targets, but this
refines the heuristic so the necessary behaviour can be easily
achieved.
* DOMAIN_NS=1 is based purely on the `-NS` suffix on the core name.
* Enabling CMSE in the compiler and outputting a secure import library
is now enabled when the core doesn't have an `-NS` suffix by either
the target label `TFM` being present or the flag `trustzone` being set.
This covers the existing ARMv8-M behaviour - TF-M builds have the TFM
label, as per its documentation; M2351 secure builds have no explicit
flagging, so we ensure that the M2351_NS target has the trustzone flag
set, and the out-of-tree secure target inherits that.
PSA code generation will be called automatically upon mbed invocation.
The autogenerated files will be created under <mbed-os-root>/PSA_AUTOGEN directory.
The "hook tools" were capable of hooking into many commands run by the build system.
To my knowlage, the only hook is the "post-build-hook". The post build hook could be
easier to reason about if the implementation is specialized for just post-build
hooking.
This commit make it much easier to point out where post build hooks are called by
making the call explicit.
Rename the existing PSoC-specific m0_core_img key in targets.json
as a more generic hex_filename key. Update makefile exporter to select
the subset of resources.hex_files matching the hex_filename value.
Without this fix, multiple prebuilt CM0+ hex files are found in the
target resources and erroneously passed to the srec_cat tool.
The fix is generic so other targets that need post-build hex merging
can use this key to pass the correct image to srecord tool.
The fix also removes sub_target key: instead, rely hex_filename json
key to detect if the hex image merging needs to be done.
The sub_target is not used in mbed-os codebase for anything else.
It is possible to override the hex file name in mbed_app.json:
{
"target_overrides": {
"*": {
"target.hex_filename": "my_custom_m0_image.hex"
}
}
Exporter hooks removed completely.
Cleanup and improvements to the comments, including removal of the redundant doxygen comments.
Code run through astyle. Additionally:
- changes to drivers/Timer.cpp reverted
- ipcpipe_transport.* files removed as they are not used for now,
- fixed condition in stdio_init.cpp to perform serial initialization only when STDIO is enabled,
- added missing resurce manager call in PWM initialization,
- us_ticker initialization changed to use pre-reserved clock divider (to avoid resource manager call).
Changed reporting level from info to debug in PSOC6.py.
Added missing includes for function declarations in startup files.
Fixed (removed) garbadge text in psoc6_utils.c
Precompiled binaries updated for recent changes in psoc6_utils.c and moved to a separate folder; README and LICENSE files added.
1. In drivers/Timer.cpp make sure that hardware timer is initialized outside of critical section.
This is because on PSoC 6 hardware resources are shared between both cores
and we have to make sure that the other core is not already using a particular resource.
This mechanism is based on interprocessor communication taht cannot be handled iside of
critical section.
2. Added support for post-binary hook function for PSoC 6 targets, so the hex image for M0+ CPU core
can be merged with M4 core image for the final image.
3. Added possibility to use hook function from exportes, so the M0+ hex image could be included
in the generated project.
4. Included hex images in the build dependency list, so the update of image is catched by the
build process.
### Description
Noticed by the online compiler:
When a user has an incomplete target definition, the error is not show
to the user. That's because it's reported as a `KeyError`. This PR adds
an outer `NotSupportedException` so that the outer catch statement knows
that this is not a build system crash, but a user error.

### Description
The NRF51 post build hook finds it's hex files using the Resources
object. This PR fixes the corner case where the hex files within a
project have a name!=path (This really only happens online).
