Hi friends,
I am working on F2812 standalone system which doesn't have JTAG
interface.Is there anyway to load my programmes into RAM and execute from RAM
without writing to FLASH.
Hope I will get help here.
Thanks,

how to load program into RAM without JTAG interface

Hi Srinivas,
You will have to generate a special hex-file which is compatible with
the 2812 SCI bootloader. This is achieved with the following command at
the end of the build sequence:
hex2000 -a -boot -sci8 -o .\Debug\test.hex .\Debug\test.out
Then, you also need a tool which communicates with the DSP in SCI
bootload mode and transmits the file over RS-232 (ideally with error
checking). You can write your own program (quite simple) or give
C2oooProg a try:

I added 28x bootloader support to C2oooProg - look under the "Special" menu.
Cheers,
Beat

Without JTAG, you should boot from SPI / SCI, eCan or whatever peripherals
you wanted.
After booting, you will copy your code to RAM, and then execute.
