i mean do i need to upload it to every new chip or is it already programmed?
Thanks.

ROM based boot loader means that every chip always contains its code?
if so - why to use a flash based one? is it always possible for any program to jump to ROM based boot loader?
Yes, every chip contains a ROM. The ROM contains the bootloader and peripheral driver library. However, the ROM bootloader only supports UART0. Yes, you can jump to the ROM based boot loader by calling ROM_UdateUART(). Refer to the ROM User's guide for details.
31.2.1.45 ROM_UpdateUART
Starts an update over the UART0 interface.
Prototype:
void
ROM_UpdateUART(void)
ROM Location:
ROM_APITABLE is an array of pointers located at 0x0100.0010.
ROM_UARTTABLE is an array of pointers located at ROM_APITABLE[1].
ROM_UpdateUART is a function pointer located at ROM_UARTTABLE[21].
Description:
Calling this function commences an update of the firmware via the UART0 interface. This
function assumes that the UART0 interface has already been configured and is currently operational.
This is great news - so there is generally no need to upload boot_serial in order to have a boot loader program with my program.
Thanks - i will surely test it and report back. the program uploads i'm doing are from UART0.
