I’m not sure I can provide any positive answer to these questions.
We used the default GR740 BSP, compiled by Thanassis Tsiodras. We did not change anything

As far as i can see, the BSS is zeroed by start.S
do you have any recommendation to perform the diagnosis you prescribe ?

As far as I can provide details
size (from binutils) can parse the ELF file, but that does not mean a lot
stack pointer is set by the linker script (if I understood correctly this part), and we did not change it
