can't seem to get Nios 2 to work on my DE1

I am getting message :

Downloading ELF Process failed.

I also see (in red) a list of things like 2) If -Stop is specified ...

but it is gone too quick to read.

I am just trying the example Hello World program.

With v11.1sp2 I (eventually) got it all working, and was able to download and run Hello World ok. So I know the hardware is OK.

Other details : I had problems with the default programmer :

Attempt to access JTAG server - internal error code 82 occurred.

I had to install v12.0sp2 standalone programmer, and now the .sop programming seems to go fine.

But not the .elf programming - this was with the "Media" processor and "Hello World" program.

Using a Win 7 64 bit system.

cheers,

Beau

More info:

I also have a DE0-Nano :

I have loaded this with a simple non-floating point "Basic" processor, and this then programs the .elf and runs fine : Hello from Nios II!

OK, now I will try the "Basic" processor on the D1 ....

And now, for DE0-Nano and DE1, for both "Basic" and "Media" processors, I get :

[Target Connection]: No Nios II target connection paths were located. Check connections and that a Nios II .sof is downloaded.

The .sof seems to download fine.

AHHH : one needs to update the processors (possibly etc) for v12

Go to the Atera University program, and download v12 :

Hello from Nios II!

on the DE0-Nano ("Basic") and DE1 ("Basic" and "Media" processors.)

Happy times !
