[meta-xilinx] Problem with Xilinx QEMU & Yocto Flow

[SMITH Peter T]

Alistair, no I did not make any changes, but I did work out what was wrong, but for the life of me I can't remember what it was other than something along the lines of finger trouble, suffice to say, I have it fully operational now. Thanks anyway. Peter

Hello Peter,

That is a strange error. I haven't seen that before with the Yocto flow.

I'll see if I can reproduce it. Have you made any changes to the default/standard flow?

Thanks,

Alistair
