Hi,
The problem was found in .cproject settings.
For some reason this block:
<sourceEntries>
<entry flags="LOCAL|VALUE_WORKSPACE_PATH|RESOLVED" kind="sourcePath" name="component"/>
<entry flags="LOCAL|VALUE_WORKSPACE_PATH|RESOLVED" kind="sourcePath" name="startup"/>
<entry flags="LOCAL|VALUE_WORKSPACE_PATH|RESOLVED" kind="sourcePath" name="CMSIS"/>
<entry flags="LOCAL|VALUE_WORKSPACE_PATH|RESOLVED" kind="sourcePath" name="source"/>
<entry flags="LOCAL|VALUE_WORKSPACE_PATH|RESOLVED" kind="sourcePath" name="utilities"/>
<entry flags="LOCAL|VALUE_WORKSPACE_PATH|RESOLVED" kind="sourcePath" name="drivers"/>
<entry flags="LOCAL|VALUE_WORKSPACE_PATH|RESOLVED" kind="sourcePath" name="device"/>
<entry flags="LOCAL|VALUE_WORKSPACE_PATH|RESOLVED" kind="sourcePath" name="CMSIS_driver"/>
<entry flags="LOCAL|VALUE_WORKSPACE_PATH|RESOLVED" kind="sourcePath" name="board"/>
<entry excluding="freertos_kernel/portable/MemMang/heap_1.c|freertos_kernel/portable/MemMang/heap_2.c|freertos_kernel/portable/MemMang/heap_3.c|freertos_kernel/portable/MemMang/heap_5.c|freertos_kernel/portable/MemMang/heap_useNewlib.c" flags="LOCAL|VALUE_WORKSPACE_PATH|RESOLVED" kind="sourcePath" name="freertos"/>
</sourceEntries>
had been reduced to this:
<sourceEntries>
<entry flags="LOCAL|VALUE_WORKSPACE_PATH|RESOLVED" kind="sourcePath" name="source"/>
</sourceEntries>
I added in the differences and the project appears to be compiling fine.
Is this an issue with the new version of mcuxpresso ide 11.2? Is it not possible to use a project that was using an earlier version of the ide and updte to the latest with ease?
