    Use a proper Hard Fault handler and identify the code that is faulting so you can ascertain why.

    You can use the .MAP file to identify functions/code by address, and you can understand register usage/content by reviewing the code disassembly at and immediately before the faulting instructions.

    Review if the code you are calling is thread/interrupt safe, and if you need to implement some mutex/semaphore to prevent re-entry.
