if i load the executable he does not load main first, he loads the P$PROGRAM_$$_INITSCREEN in my bin start address 0x80010000
so the P$PROGRAM_$$_INITSCREEN is executed right at 0x80010000 which is the entry address
I don't knew how to force the linker to start at main (PASCALMAIN)

You know that you could look at the documentation for ld?

Also you shouldn't directly start PASCALMAIN, but your RTL should have a dedicated entry point function that does some low level setup (e.g. arguments and such) and that then calls PASCALMAIN (just look at the Linux RTL for example that has the _start symbol in its various startup files in rtl/linux/<arch>).

Read Setting the Entry Point. So either specify the entry point symbol with the -e _start command line option to the linker, or add entry(_start) to your linker script.

The compiler often use the entry keyword in its own target linker scripts.

Edit: Changed symbol name to _start after reading the follow-up discussion.

this isn't working because fpc creates several .text sections.
this is why we need the si_prc.pp

The test.txt file looks like the compiler generated assembler for the test.pas unit only so it will not contain code from another unit. One can for example use objdump -S to disassemble the final linked executable, objdump -t or readelf -s to list all the symbols linked into the executable image.

why is it the case? what to do?

can't do this, my .elf is in a unknown format, I use mipsel-unknown-elf-ld

Because your TExternalLinker descendant also needs to override InitSysInitUnitName. Look at the other targets. And best also override WriteResponseFile to dynamically create the linker script (again, look at the other targets).

The test.txt file looks like the compiler generated assembler for the test.pas unit only so it will not contain code from another unit.
why is it the case? what to do?

Because that is how Pascal works?! Every unit is its own object file and thus its own assembly file. It's the linker's task to link these together.

One can for example use objdump -S to disassemble the final linked executable, objdump -t or readelf -s to list all the symbols linked into the executable image.

can't do this, my .elf is in a unknown format, I use mipsel-unknown-elf-ld

That does not mean that the format itself is unknown, only that the platform is not specified. Also there should be a mipsel-unknown-elf-objdump.
