Hello! Thank you for your previous answers!! Now my code is working with interrupts... but only with debugger because I've made a "DSP 56800 EABI stationery project". Therefore my program can't work in "stand alone mode". How is the best way to make my program to run alone, without debugger?? Is is better that I implement my code with a "SDK stationery project" who allows the stand alone mode directly, but in this way, the implementation of interrupts is different than with a simple assembler vector file... (as I just succeed!! :-)) Or, is it better to modify my EABI stationery project to make it run "by itself" ?? Thank you in advance!! regards, Pascal |

I'm using the EABI stationary and it is able to run
"standalone". I modified the reset vectors file to have the RESET and COP, both pointing at the main routine, and both vectors mirrored to the BOOT section (meaning that the same RESET and COP vectors are copied in both P:0x0000 and P:0x8000). By the way, can anyone explain me how does the 5680x boots from reset? does it fetch the RESET/COP from 0x0000 or 0x8000 ? The user manual is not clear about this. I found that writing both vectors allows me to run without the debugger. But which one is the DSP using? Thanks !

I would
suggest you use the SDK stationary. In this way you will get the proper start up
code. In addition in the case of the interrupt for the 56F800 product you will
also get support for nested interrupts in the SDK interrupt support. You will
also get access to other software such as signal processing libraries and a set
of macros to perform specific chip functions.
The SDK product is being replaced with a
product called Processor Expert. The SDK software libraries have been broght
forward and put into the Processor Expert product which provides many of the
same benefits as the SDK, but with a much improved graphical user interface and
support across many more Motorola processors such as the 8 and 16
microcontrollers and the 56800/E hybrid processors. You might also consider
using PE which is available in the new CodeWarrior 6.0 product.
Thanks.

What do you mean by "are mirrored" ? Are they mirrored by
Codewarrior or is it internal to the DSP circuitry? why is that there are two RESET and COP vectors? which one is used and when ? The user manual specifies two possible boot modes: normal and boot. But how do you enter those two different modes?

RE: [motoroladsp] stand alone
"Mirrored" means, when the address p:0x0000 is issued, rather than seeing the value stored in program data flash from PFIU0, the data at p:0x8000 is viewed instead from BFIU. The more interesting question is what do you see if the BFIU and PFIU or both would be disabled, and external memory is the only program memory available??? Would external memory p:0x0000 actually be read? I suspect so if in external memory mode. Jerry. -----Original Message-----

I'm sorry about this. It is not clearly explained in either manuals
(family and user). The DSP fetches the reset vector from where: boot (0x8000) or program (0x0000) ? Say I have a Reset (0x0000) that points to my main routine. Somehow the flash becomes corrupt, and the code performs an illegal operation or you get a COP reset. Say that the reset vector at 0x0000 becomes corrupt too. My question is: how the hell does the dsp know that the vector at 0x0000 has become corrupted and therefore boot from 0x8000 ? or does it always boot from 0x8000 and you have to always validate the flash contents? Which vector should I program from codewarrior? 0x0000 or 0x8000 or both?

I'm clear now. In page 3-30, it says that "A boot flash is
provided to handle device initialization in the event the program flash becomes corrupted for any reason. The hardware and COP reset vectors, $0000 and $0002, are mapped into the boot flash at locations $8000 and $8002." So I understood that there were two possible booting modes for the DSP: "normal" from 0x000 or "boot" from 0x8000, which is not true. I was missing : "...the locations 0x0000 - 0x0004 of PFlash are inaccessible..." "...First four words of BFlash are mapped into this address space instead..." "...where to program your reset vecotr jumps - pick any of the two possibilities [0x0000 or 0x8000, eventually 0xF800 on 807]" "... always you'll be programming the BFlash - it's the same piece of memory on both locations..."
