Determing application size in memory.x

[mdrssv]

Hi,

I've been trying to determine the size of my flashed application using the linker script without much success however.
I've tried
PROVIDE(__application_size = __etext - __stext) which resulted in a value of 57 which is wayy to small to be realistic, as did PROVIDE(__application_size = SIZEOF(.text))

Which makes me wonder if it's even possible to embedd the size of the application and if so how ?

how did you read the value provided by the linker? You'd need to do something like:

extern "C" {
    static __application_size: u8;
}

let application_size = core::ptr::addr_of!(__application_size);
