Mbed-OS build fails for FUTURE_SEQUANA/family of targets with ARM Compiler 6.11 #9578
Description
Description
Mbed OS will be upgrading to ARMc6 Toolchain with upcoming releases. We are in the process of ensuring that all currently supported targets successfully compiles/passes tests with ARMC6 toolchain but we do have some targets currently failing the build with ARMc6 toolchain. The failures are in source code under targets folder and thus needs to be updated.
The error and warning details are as follow:
When compiling with ARMc6 toolchain for FUTURE_SEQUANA(and other related targets - FUTURE_SEQUANA_M0, FUTURE_SEQUANA_PSA, FUTURE_SEQUANA_M0_PSA) build fails with following errors:

Targets Affected: FUTURE_SEQUANA, FUTURE_SEQUANA_M0, FUTURE_SEQUANA_M0_PSA, FUTURE_SEQUANA_PSA
Toolchain used: ARM Compiler 6.11 (Version 6.11)
Note that there may be other changes required to make build successful for ARMc6, so please address them as well.
How to reproduce the issue?
- Install ARMC6 compiler with version 6.11
- Set ARMC6_PATH config variable as below.
mbed config --global ARMC6_PATH<Path to ARMC6 Toolchain bin directory> - Run the compile as: mbed compile -t ARMc6 -m
<target name>
Note that you may see an "Error" when trying to use ARMc6 with "mbed compile". This is expected, but the compilation process should continue to proceed. We will be removing this Error/Warning once we switch to ARMc6 completely.
How to generate Pull Request to fix ARMc6 issues?
Please generate your pull requests addressing ARMc6 build issues with feature-armc6 as the target branch(not master branch).
