After installing 5.1 load up kernel produce errors

Hello Friends!

I have installed Nios II IDE Version 5.1 WEB and Quartus 5.1 WEB.

After I have compiled a kernel I try to load it up,

but the following messages occurs:

using cable "usb-blaster [usb-0]", device 1, instance 0x00

resetting and pausing target processor: ok

reading system id at address 0x021108c8: fail

id value does not match: read 0xffffffff; expected 0x079d820c

timestamp value does not match: image on board is older than expected

read timestamp 0:59:59 1970/01/01; expected 5:21:22 2005/10/21

leaving target processor paused

What could be the reason for these errors?

Bye, Lothar.

    I'm not sure but it looks like there is an older design (with Nios2) in your system and the new version doesn't particulary like that.

    You might want to try to use a newer version of the nios2 and the upload program you use (sof system used to write to flash...)

    Lothar,

    It looks like your kernel was compiled against a different Nios core than the one you have loaded.

    Verify that you are compiling the kernel to the same core that exists in your fpga.

    Your system ID value is updated anytime you make any changes to your core in SOPC builder. If you are updating your core, make sure your working directory is the same as your project directory. Occasionally, I will open files in a different directory other than my current project directory, make a few changes in SOPC builder, load my new core, and get a system ID error. This is a result of previously opening files in a different directory. This ends up changing my "working" directory. My new core is actually located in the last directory I had opened. As a result, I end up loading a "stale" nios core, and I get the system ID error.

    You can figure out what your working directory is by typing "pwd" in the tcl console.

    Hello!

    I think the main problem is that I installed Nios II IDE Version 5.1 WEB and Quartus 5.1 WEB over Nios II IDE Version 5.0 and Quartus 5.0.

    Perhaps is better to deinstall both before upgrade.

    Now I have downgraded to version 5.0 to save time at the moment.

    Bye, Lothar.
