@mprse Could you include more detail in the commit message and PR title? I don't know what you are updating when you just say that you update. |
…oryPool.h header file. Provide fix for pool buffer size: pool block size must be a multiple of 4 bytes. Add assertion to forbid creation of MemoryPool object with queue size equal to 0. Update description of free() function. Add information about statuses returned by this function.

I'm proposing a different fix for this issue in CMSIS repo, please see the below URL with description. Once/If that gets through we have to make changes to mbed-os repo to use the new alignment macro instead of hard-coding the alignment in MemoryPool.h which creates memory alignment knowledge duplication. In case, it doesn't get through we can use the solution in this PR as short-term fix. |
👍 Thanks for going upstream, let's wait for CMSIS team review |
