Set the names of the Ethernet interfaces that are exposed from a first boot so they are aligned with those described by Mellanox/NVIDIA documentation for the BF3. Those tmfifo and oob interface names are describeded at: https://docs.nvidia.com/networking/display/bluefielddpuosv460/host-side+interface+configuration When running the native Ubuntu on the BF3 board, the following udev rules are set: $ cat /etc/udev/rules.d/91-tmfifo_net.rules SUBSYSTEM=="net", ACTION=="add", DEVPATH=="/devices/platform/MLNXBF01:00/virtio1/net/eth[0-9]", NAME="tmfifo_net0" $ cat /etc/udev/rules.d/92-oob_net.rules SUBSYSTEM=="net", ACTION=="add", DEVPATH=="/devices/platform/MLNXBF17:00/net/e*", NAME="oob_net0", RUN+="/sbin/sysctl -w net.ipv4.conf.oob_net0.arp_notify=1" The default CX ports of the BF3 are: ubuntu@bf$ ip link show p0 4: p0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000 link/ether a0:88:c2:xx:xx:xx brd ff:ff:ff:ff:ff:ff altname enp3s0f0np0 ubuntu@bf$ ip link show p1 5: p1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000 link/ether a0:88:c2:xx:xx:xx brd ff:ff:ff:ff:ff:ff altname enp3s0f1np1 Signed-off-by: Vincent Jardin <vjardin@free.fr> Signed-off-by: Julien Olivain <ju.o@free.fr>
Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
