[meta-xilinx] What version of oecore/yocto for microblaze

[Matthew Clark]

Nathan:

Thank you very much.  I was struggling getting git to work through my
corporate proxy, so I gave up and just downloaded the zip files.  I fumbled
a download and didn't notice it.  Once I fixed that issue.... I was able to
build a microblaze image today.

May I ask if this is the proper forum for me to be asking startup
questions? I don't want to abuse a list intended for developers.

Thanks again.
