Hello

Hi

are you sure the qemu problem is related to TE0720?
Do all other petalinux projects start correctly in qemu?

[Fady]

Hi,

I'm not sure what is the problem.
This is the first petalinux project that i'm tryin to boot on qemu.

[Antti Lukats]

Try with plain zynq template design first.

[Fady]

Hi,

Can u send me the link where i can find the plain zynq template design?
I'm using trenz TE0720 + TE0701.

www.xilinx.com, downloads petalinux...

then please type:

petalinux-create --help

and follow the Instructions, it will create just plain empty petalinux project for you, start from there.

i did the following:
1-$ petalinux-create --type project --template zynq --name test_1
2-$ petalinux-config --get-hw-description=<path-to-directory-which-contains-hardware-description-file>
(i used the .hdf file created from TE0720-02.zip ref design package download-unzip
http://www.trenz-electronic.de/download/d0/Trenz_Electronic/d1/TE0720-GigaZee/d2/reference_designs.html)
3-$ petalinux-build
and i got an  ERROR: Failed to build linux

I asked you to make empty template project, this is REALLY REALLY VERY SIMPLE:

petalinux-create --type project --template zynq --name qemu_test
cd qemu_test
petalinux-config
<< hit enter 2 times!
petalinux-build
<< wait
petalinux-boot --qemu --kernel

I get error>>>

I am sorry, it all works here as explained to you.
qemu is not starting, it never has, but all the rest works without any issues.
