is writing ready flash this involved?

Along these lines?

LR_IROM1 0x08000000 0x00804000 { ; vector/reset ER_IROM1 0x08000000 0x08004000 { ; *.o (RESET, +First) *(InRoot$Sections) .ANY (+RO) } RW_IRAM1 0x08004000 0x08008000 { ; eeprom area .ANY (+RW +ZI) }
}

LR_IROM2 0x08008000 0x08100000 { ER_IROM2 0x08008000 0x08100000 { ; remaining of code.. .ANY (+RO) }
}

Along these lines?

LR_IROM1 0x08000000 0x00804000 { ; vector/reset ER_IROM1 0x08000000 0x08004000 { ; *.o (RESET, +First) *(InRoot$Sections) .ANY (+RO) } RW_IRAM1 0x08004000 0x08008000 { ; eeprom area .ANY (+RW +ZI) }
}

LR_IROM2 0x08008000 0x08100000 { ER_IROM2 0x08008000 0x08100000 { ; remaining of code.. .ANY (+RO) }
}

Hope this is more readable.

LR_IROM1 0x08000000 0x00804000 { ; vector/reset

ER_IROM1 0x08000000 0x08004000 { ;

*.o (RESET, +First)

*(InRoot$Sections)

.ANY (+RO)

}

RW_IRAM1 0x08004000 0x08004000 { ; eeprom area

.ANY (+RW +ZI)

}

}

LR_IROM2 0x08004000 0x08100000 {

ER_IROM2 0x08004000 0x08100000 { ; remaing of code..

.ANY (+RO)

}

}

This is something that you will understand best if you do it yourself. You should try to build with that scatter file and see what fails. You have a general idea of how to use the scatter file to do what you want to do, but have a few errors that you will go "why was I thinking that would work" once you figure them out.

One hint: +RW variables cannot go into flash. // this is actually more than 1 hint
