linker, bootloader

niket_zope — Wed, 04 Aug 2021 04:26:27 GMT

Hello Everyone ! I am a hobbyist.

I am new to linker script modification, (merely focusing on .icf file generated by IAR).

working on development board. MKE1xZ256VLH7.

my requirement are:

I need to create separate sections

1. for Bootloader with 4KB read & exec (best possible to keep where reset vector resides)

2. application code (left space) as read only in ROM

@mjbcswitzerland can you help ?

Can any one check my changes & provide feedback please !

Attaching my linker modifications.

Hi,

If you develop the bootloader, you needn't change the icf. If you develop the application, then you need to change the icf. You can refer this link. It has the icf modification.

Have a great day,
TIC

You can get proven, out-of-the-box boot loaders for most kinetis parts from the uTasker open source project on GitHub: https://github.com/uTasker/uTasker-Kinetis

This contains IAR projects containing linker script files for building the loader and linker scripts for building applications to be loaded that can be used as reference if you prefer to develop a new loader, or as reference for building foreign applications.
