  Unable to Boot the Emulated System
Posted by: wmurwin - 12-16-2015, 08:53 PM - Forum: Public Support - Replies (2)

Unable to Boot the Emulated System

Using the instructions from the Xen Zynq Distribution User Manual from section 3.4.1 "Booting the emulated system".

I get the following error:
ERROR: No hardware dtb found. This is required to boot ZynqMP

But if I look in $RELEASE_DIR/dist/images/linux I see a xen.dtb

I am using petalinux-boot from 2015.4

  Enable multiple CPUs in QEMU
Posted by: jarvis_roach - 06-18-2015, 08:02 PM - Forum: Public Support - No Replies

1. In dts/xen.dts, change device_type = "none"; to device_type ="cpu"; for each core you want to enable.
2. In dts/xen.dts, change maxcpus=1 to maxcpus=2; or maxcpus=3; in chosen/xen,xen-bootargs and chosen/xen,dom0-bootargs.
 *Setting maxcpus=4 seems to cause some sort of deadlock during kernel initialization. 
3. Build new /tftpboot/xen.dtb from dts/xen.dts (make install-xen-dtb or use dtc).


From dom0, cat /proc/cpuinfo or xl cpupool-list will show the extra cores in use.

  QEMU, Multiple NICs
Posted by: jarvis_roach - 06-18-2015, 07:53 PM - Forum: Public Support - No Replies

1. In dts/xen.dts, change status = "disabled"; to status = "okay"; for each Ethernet controller you want to use in the QEMU target.
2. Rebuild /tftpboot/xen.dtb from dts/xen.dts using make install-xen-dtb or dtc.
3. For each NIC you want to use, including the first one, add "-net nic,vlan=0 -net user,vlan=0" options to the QEMU invocation.
4. From dom0, issue 'udhcpc -i ethN' for each NIC other than eth0 that you want the QEMU DHCP server to assign an address to.
   *Note that using vlan=0 for each configuration pair means that all NICs will be on the same virtual network, and the DHCP server will assign a unique IP address. If you assign each NIC to its own vlan (by using unique vlan IDs for each configuration pair), then the DHCP server will assign the same IP address (10.0.2.15 by default) to each NIC.

From the qemu monitor (normally entered by ctl-a c from serial0)  info network will show how the NICs are configured. With the first two Ethernet controllers enabled and put on the same vlan, info network returns:
hub 0

 \ user.1: index=0,type=user,net=10.0.2.0,restrict=off
 \ ps7-ethernet@0xFF0C0000: index=0,type=nic,
 \ user.0: index=0,type=user,net=10.0.2.0,restrict=off
 \ ps7-ethernet@0xFF0B0000: index=0,type=nic,
ps7-ethernet@0xFF0D0000: index=0,type=nic,
ps7-ethernet@0xFF0E0000: index=0,type=nic,
