After some hours messing around I figured it out.

I have to make it volatile! If I make the constant volatile I can find it in the HEX file just by searching after the hex numbers in a row.

I hope this information might be usefull for others struggling with the same thing!

''I have to make it volatile!''

Funnily enough, a similar point has just turned up at

''my

guess

is that, without 'volatile', the compiler may decide not to read the ROM at all, but to use ''immediate'' data instead...''

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
