Hi,

I need tos et the Reset Vector to my own code, without rts430xxx library functions.

I will write my own bootloader, in a fix memory range in that is also include the interrupt vectors. (0xf000 - 0xffff)

So I flash once the bootloader with JTAG and then the bootloader and Interrupt vectors must deleted and reflashed.

My problem is that the compiler/linker always set the reset vector to "_c_int00_noargs_noexit" and execute some RTS430 functions before start my own code. but the rts430 code can be on different ranges.

(sorry for my english)

Thanks for that. But I must directly jump in my program. The _system_pre_init function jump also in the RTS range.
I must jump to 0xf804 , the RESET vector must be 0xf804 ...

It is possible to place the entry point at a specific address if that is what you are looking to do. Please see this wiki page.

If this does not help you achieve what you need I would suggest asking in the MSP device forum as well as the experts there could provide answers more specific to how this is generally done with MSP430 devices.
