Dear all,
Does anyone knows how to create a vector interrupt table for c6711 dsk and
how to write an ISR for Timer0? I'm using CCS v1.23.
Many Thanks,

This is easier to do with BIOS. It can also be done without BIOS as well. The question is how do you want to do it.

Hi,
Thank you for the reply. I did that in bios before and I agree that it was much easier. However when i burn the program into rom, any function called by bios will not work.
Tt’s the reason why I’m trying to write it manually. Please advice me.
Many Thanks,
CK

What you are describing is an attempt to *run* from EEPROM. If you do that, BIOS (or
any other boot code) thinks memory is r/w and tries to store local variables etc.
Clearly that's not going to work.
You have to use the bootloader to boot (load) from EEPROM to internal memory first,
then run. I don't recall specific CCS steps, but I know you can search thread
archive for this; it has been discussed many times.

Ya maybe data should be RAM... I'm not sure, although I think you're getting closer
to the answer.

Hi,
I tried that out last night. Didn't work... What other possibilities could
there be? By the way tis is how I assign my memory sections:
SDRAM: code/data
IRAM: code/data
FLASH_BOOT: code
FLASH_REST: code
Thanks,
CK

Thinking that you are the 1,000 person to need to boot DSP/BIOS from Flash on C6xxx
device, I did this Google search:
+BIOS +boot +Flash site:dsprelated.com
and this thread came up:
http://www.dsprelated.com/showmessage/5903/1.php
It might be helpful, suggest also to find others like it. DSP Related contains all
c6x Yahoo Groups posts plus comp.dsp, so it's a super source.

I dont know if this would be useful to you, but you could check out
this new application note from TI on "Creating a Second-Level
Bootloader for FLASH Bootloading on TMS320C6000 Platform With Code
Composer Studio". The application note series number is: SPRA999A
