 In short: Yes, you need to write the startup code that initializes `.bss` and copies
 `.data` from flash to RAM manually when doing bare-metal programming.

+Also, supplying `-nostdlib` has the same effect as `-nostartfiles` *for this particular

+Regarding this topic, please also read "[From zero to main(): Bare metal C][zeromain]"
+on interrupt.memfault.com ([archive.org link][zeromainarch] in case website goes down).
+
+Another source that really made things "click" for me is
+"[Bare-metal C programming on ARM][bmarm]". Although the book handles the Cortex-A
+series, the section about startup code is really worth a read.
+The book is also [available as PDF][bmarmpdf] (again, [archive.org link][bmarch]).
