I have considered buying an LPC1768 development board which comes with bootloader installed. Bootloader makes this board show as a mass storage when connected to USB. Flashing is made without any programming tools, just drag and drop your .bin file into the folder. Starting point for application should be set to 0x2000. Manufacturer have an instructions which show how this is done in uVision.
I have now installed LPCexpresso and cant find place where to set that starting memory address. So how is this done?

In the demo code pack from CodeRed you will find something called RDB1768cmsis_LedFlash_64k. This shows how to relocate the code to arbitrary address. Modification of linker scripts is required. There is also an article on this topic at CodeRed support site.

Thanks for quick reply. I did not find that demo, but I found out how to edit those linker scripts. I disabled auto management of linker script from project properties -> MCU linker -> target, copied and renamed original .ld files generated by LPCexpresso, defined where to find my own linker scripts. Also edited linker script so that includes refers correctly my newly created copies of _mem.ld and _lib.ld sripts.

I put my own linker scripts to project root /linkscript folder at first it did not work. I found out that it requires that _mem.ld and _lib.ld have to be located at project root. Using <> instead of "" in include clauses seems to work also.

Can you please tell me how or where you found the documentation on how to change the linker script to change the starting address of the program. Thanks for your help.

Ok, I was able to find what I was looking for in the <PROJECT NAME>_mem.ld file. Thanks for your help guys.
