xilinx-zynq-a9 machine #1

Closed radwrob closed 7 years ago

radwrob commented 7 years ago

Hello Xilinx,

Now I use the Xilinx's QEMU platform (xilinx-v2016.3 tag) instead of PetaLinux. When I start this project on machine arm-generic-fdt-plnx everything is working properly. While I changes to the machine xilinx-zynq-a9, platform qemu does not stop and does not display the message:

QEMU waiting for connection on: Disconnected: unix: ./ qemu-tmp / qemu-rport-_cosim @ 0 server

Linux kernel is loaded instead of this:

Uncompressing Linux ... done, booting the kernel.

Any ideas why this happens?

Thanks, Radek

Hi Radek,

Yes, in order to co-simulate, you need to instantiate the remote-port nodes. These nodes are described in a cosim device-tree that arm-generic-fdt-plnx consumes. When you run the xilinx-zynq-a9 machine, because that machine does not support co-simulation, the remote-port nodes are not created and a normal boot begins.

Hope that helps,

Best regards, Edgar
