I am using MCUXpresso with MK10DN512VLQ controller. I need to use my own startup code and linker file. Can I get any documents or reference to do?
you are free to use your own startup code, simply modify the one present in the project. If you are not familiar with the startup code, you might have a read here: Optimizing the Kinetis gcc Startup | MCU on Eclipse
Just make sure your startup symbols match the one used in the linker file.
The MCUXpresso IDE uses managed linker files (search for 'managed linker scripts' in the IDE Help). As long as you only do small modifications, you can do this with with extensions (see Tutorial: Porting BLE+NRF Kinetis Design Studio Project to MCUXpresso IDE | MCU on Eclipse how I'm using this). But you can do your own linker file if you know what you do.
I hope this helps,
Compiler which i am using MCU C Compiler. Which does not have option to do so. Can you refer document related to this compiler?
Erich has sent the pointers you should need.
However, we could likely be of more help if you explained what you are trying to achieve?
