I am using lpc1768 MCU and id keiluvesion4.
I want to create dummy main() function with different name like mains().
And i want to execute my dummy mains() function.
In startup file i replaced __main into __mains.
But compiler give error.
Undefined symbol mains (referred from sartuplpc17xx.o).

So have you looked at how others do that?
It is a very common requirement indeed - there are plenty of examples on the interwebs.
Almost certainly, NXP themselves will have an example.
The lpc1768 was the very first MCU for mbed - so there will be solutions there.
Google "lpc1768 bootloader" and "lpc1768 firmware update", etc ...
