Hello Rupok,

Can you share your solution ?
I've the similar problem and can't resolve it since 3 days.
I've tried 2 different projects - one with On-Chip memory, other with SDRAM.
The result is the same in both cases - downloading begins ... then fails suddenly.
Here is the message in console:

Using cable "DE-SoC [USB-1]", device 2, instance 0x00
Pausing target processor: not responding.
Resetting and trying again: FAILED
Leaving target processor paused

Thanks in advance.

Pavel.

check the resets and clock signals to the core CPU. I'd say there is a good chance either that it's not receiving any clock or that it's stuck in reset. For example with the wrong polarity defined on the reset input.

Hi,
I found out that I had not moved one of the keys on my MAX 10 board up to the correct position. By moving key 9 to the up position Nios II was able to upload the ELF file without a problem.
