Multiprocessor starting from flash

Hi All,

I'm testing a multiprocessor system with 3 cpus. I could download each software to its memory area (one for each cpu) using the nios2-download command -> it's ok.

Now, I want to start cpu's from reset address (my reset addresses are pointing to flash), but occurs some problems when I try to do that:

$ nios2-flash-programmer --cable='USB-Blaster ' --device=1 --sidp=0x02110CE0 --id=342301955 --base=0x00000000 --instance=1  standard.flash
Using cable "USB-Blaster ", device 1, instance 0x01
Resetting and pausing target processor: OK
Reading System ID at address 0x02110CE0: verified
No CFI table found at address 0x00000000
Leaving target processor paused

This error occurs for all nios2-flash-programmer commands that I try to run.

Any idea?

I tryed to download a monoprocessor system .sof before run the nios2-flash-programmer, and it was successful, the flash was wrote. But when I download a multiprocessor sof, nothing happens. The cpu's doesn't start from flash.
