What is the error?

Do you remove the dot in the linker script as well?

Doesn't exist where?

If you want the contents of the section to show up in hex files
and linker output, you probably need to set the section
attributes like this:


.section .text2,"a",@progbits

Technically, you probably should be using an "x" flag for a
text section as well. It seems to work fine without it, but
it's the right thing to do:

.section .text2,"ax",@progbits

For a writable section, add a w to the flags string.

You might want to do

$ into as

and read the stuff on the .section directive.
