I've no experience with that device at all, but from experience with

initialisation of variables in the bss.

[Hmmm... I don't see your post, David.  <frown>  Something must be
hosed in my server.  (actually, I don't see MANY posts, here!  Quiet?)]
BSS is a good warning.  I've been using other tools with the ARM that
I've "abandoned" ("moved past" might be a kinder way of reference).
I tend to rely on vendors tools *if* there is likely to be some
bug that the tools can workaround -- that a third-party vendor
may not be aware of (or address).

For the cortex M4, I'd avoid using TI's toolchain if at all possible.
Download a copy of GCC from ARM.

This is an A53 (ARMv8) -- at least the "main cores" are.  There's
also an M4(F) -- and, as typical of ARM, a couple of other
"specialty processors".

The general rule I've found to be true for the past 40 years is that
software/tools supplied by silicon vendors is crap.

That's a direct analog of the issues with "sample applications" for
hardware devices!
What about "support"?  Are there anything other than trained monkeys
available?  Or, is everything "forum based" (what a great scam!
outsource your support to your CUSTOMERS!!)
