pub fn app_elf_sha256() -> &'static [u8; 32]Expand description
The ELF’s content hash, straight from the esp-idf application descriptor —
the first bytes distinguish two images built from the same commit with
different uncommitted edits. Unambiguous with no consumer input needed: it
is a function of the linked image, computed and patched in by espflash.
Requires app_desc! to have been invoked (see app_desc()).
