Hi,

I am currently working with the last version of the tools (Quartus II 10.1 SP1 and Nios II SBT 10.1 SP1) and I have to same problem as described initially in the thread:

(...)

Using cable "USB-Blaster [USB-0]", device 1, instance 0x00

Resetting and pausing target processor: OK

Reading System ID at address 0x01201010: verified

Initializing CPU cache (if present)

OK

Downloading 01100020 ( 0%)

Downloading 01110000 (44%)

Downloading 01120000 (89%)

Downloaded 144KB in 2.4s (60.0KB/s)

Verifying 01100020 ( 0%)

Verify failed between address 0x1100020 and 0x110FFFF

Leaving target processor paused

(...)

This always happens when the code size is above 64kB (0x00010000). Sometimes at the beginning, sometimes afterwards. But always during the veryfing process.

The design I use is rather small (CPU + JTAG-UART + SYSID + AVALON-TRISTATE-BRIDGE + SRAM + CFI + PIO).

I try the download command from the shell but th result is the same.

When we "google" the error, we can see that it happens regularly since about the version 5.

Did someone has a real clue or a workaround for this ?

note that the code is working. i tested it by downloading it in the flash with the flash programmer. the problem only appears in debug (or run) mode.
