Microblaze + uClinux issues

Hi all,

I've been struggling for two days now to get xapp730 from Xilinx to work. I've built the hw (wo FSL as it seems to be confusing the debugger) and can communicated with the CPU via xmd. However, the dow command seems to be failing. See transcript of xmd session below.

Any help or input is very much apprechiated.

Best regards,

Johan Thelin

Hej Johan,

Do you have a file called xmd_.opt in the directory download? replace with the name of the microblaze instance from the .mhs file. It can contain automatically settings which mess up the XMD communication. This file get automatically used if you click on the XMD icon in XPS.

Hej Johan,

Forgot to tell you to delete or rename that file if you have it.

Hi G=F6ran,

Thanks for the quick reply - but the trick was to not be stupid. When synthesizing the route and place tool reports timing met, but the timing analysis tells me that the system cannot be run at 100MHz (which xapp730 claims). Reducing the clock to 66.67MHz made everything work as intended.
