Stephanos Ioannidis ecfd78776d tests: lib: mem_alloc: Increase malloc heap size for newlib test The newlib full malloc implementation (i.e. non-nano) requests a relatively large 4096-byte memory chunk through `_sbrk`, which exceeds the configured 512-byte heap size. This commit changes `CONFIG_NEWLIB_LIBC_ALIGNED_HEAP_SIZE` from 512 to 8192 in order to increase the size of the heap memory used by the newlib malloc function. For more details, refer to the issue #21167. Signed-off-by: Stephanos Ioannidis <root@stephanos.io>		2020-02-14 10:52:53 -06:00

Title: Kernel Access to Dynamic Memory Allocation functions provided by
Standard Libraries

Description:

This test verifies kernel access to the dynamic memory allocation functions
provided by standard C libraries supported in Zephyr:
NEWLIB and MINIMAL_LIB.
It is intended to catch issues in which a library is completely absent
or non-functional, and is NOT intended to be a comprehensive test suite
of all functionality provided by the libraries.

Building and Running Project:

This project outputs to the console.  It can be built and executed
on QEMU as follows:

    make run

--------------------------------------------------------------------------------

Troubleshooting:

Problems caused by outdated project information can be addressed by
issuing one of the following commands then rebuilding the project:

    make clean          # discard results of previous builds
                        # but keep existing configuration info
or
    make pristine       # discard results of previous builds
                        # and restore pre-defined configuration info
