DE0_Nano_QSYS_DEMO BSP error with Quartus 15.1

Hello,

I downloaded the DE0_Nano_QSYS_DEMO from the DE0-Nano_V.1.2.0_CDROM, and can't run the demo under latest Quartus (15.1)

Here are the steps I followed:

* Upgrade IP cores in quartus

* Regenerate design in Qsys

* Open the software/DE0_nano and software/DE0_nano_BSP in Nios II Eclipse

* Try to generate the BSP since the IP core changed

Generating BSP in eclipse gives out a pop up with this error:

--- Quote Start ---

Error executing 'nios2-bsp-generate-files --bsp-dir . --settings settings.bsp', unexpected return code 1.

Error message:

SEVERE: The device is not ready

SEVERE: nios2-bsp-generate-files failed.

--- Quote End ---

Running it from cmd.exe, with the debug flag I get this log:

I don't really understand what's going on and can't pinpoint the error. What can I do to fix this?
