I am very new to linux on microblaze.I HAVE CREATED A HW CONF FOR ml 505 BOARD.i HAVE GENERATED DTS FILE AND .bit FILE on ISE 13.1.I am trying to create image file on an Ubuntu PC.While trying to make the image , it is giving error as microblaze-unknown-linux-gnu- not found.This happens even when I do the make clean command.But tool chain is present in the PC in my working directory.

Kindly help me to solve the problem.

Thanks for your nice blog.
I followed the steps you wrote on this page but I faced a serious error at the last step of my process:

… some omitted messages during compiling …

The kernel version which I’m using is 2.6.35.

I did it on my machine fitted with RHEL 6.1 32bit.

I think it’s a matter of GCC. Could you tell me a hint for solving this?

Thanks for your advice in advance.

is it possible to give a small info on how to simulate it with Qemu. I am sitting for more then 3 days but unsuccessfully.

Thank you for such informative posts!

Could you please upload linux-2.6-xlnx.git (with kernel 2.6.38) on your website ?
Xilinx moved to kernel 3.0 and Zynq support recently…

And no, I went directly for the real thing.

very nice blog, thank you very much for sharing this information.
Did you ever try to simulate your kernel in qemu?

Best regards
