hi all,
This is regarding EB 55 board.
On this board,after Reset program starts to execute from flash connected at NCS0(which is also linked at 0x00000000 ).In flash boot loder is stored at address 0x01000000 (equivalent to 0x00000000 before remap)and application program is stored at address x01100000(equivalent to 0x00100000 before remap).
Then in this case ,

1.IS BOOT LODER EXECUTED BEFORE C STARTUP CODE?

2.IF BOOT LODER IS EXECUTED BEFORE C STRTUP, THEN IS IT EXECUTED AT SLOW CLOCK WITH NWS = 8?(AS LOW LEVEL INITIALIZATION IS PERFORMED IN C STARTUP)

3. FROM WHERE CAN I GET SOURCE CODE OF EB55 BOOT LODER?

Hi,
the question is wrong. You can't ask what is running first because this are several things .

Bootloader: This one starts the system.
C-Startup-Code: Makes all thinks, to start the C-part of your program.

If you use a bootloader and write it in C, you need also a C-Startup routine inside the bootloader.
If you write firmware for an embedded device, your firmware includes a bootloader part (which is responsible for the controller startup and the application itself). If your firmware is assembler based, you do not need a C-Startup-Routine.

You can look at the LED sample program. This includes system startup and C-Startup-Routine .
