#22243 Thanks cal,
Appreciate your help, it works like intended and I was able with your explanation to get going.
Tricky part was the real understanding of the translation from
Code: Select all4020bf8a:   c40000           extui   a0, a0, 0, 13
4020bf8d:   3ffe87           bbsi   a14, 24, 4020bfd0 <divide+0x34>

To the address
Code: Select all3ffe87c4

Due to the (I think) disassembling sometimes "reversing" the little endian mode and display in big edian.
Solved that by looking at the objdump -s of the irom0.text ouput.
Limited the output of all -s to objdump -s -j.rodata and now up to scanning/searching the files automatic.
