Tango recipes for OpenEmbedded Bitbake

# 9 years ago
raph38130	Hi tangoers, for those who need a customised linux distribution including tango, here is the successfull result of my attempt with OpenEmbedded & Poky. (no apt-get required) It has been tested with a Zedboard (xilinx zynq fpga = dual arm7 cores) (TangoTest devices). I will give a try with raspberry pi 2 and BBB asap. you need 4 recipes (zeromq omniorb4 tango) hope it helps… for beginners, more info here : https://github.com/Xilinx/meta-xilinx www.openembedded.org attachments are omniorb4_4.1.7.bb, omniorb-native_4.1.7.bb, tango_8.1.2.bb, zeromq_3.2.5.bb 5 tango vdi for testing http://dl.free.fr/nXmWNLGqM (sorry I dont how to edit files name) Poky (Yocto Project Reference Distro) 1.7 zedboard-zynq7 /dev/ttyPS0 zedboard-zynq7 login: root root@zedboard-zynq7:~# uname -a Linux zedboard-zynq7 3.18.0 #5 SMP PREEMPT Mon Jun 8 14:59:40 CEST 2015 armv7l GNU/Linux root@zedboard-zynq7:~# cat /proc/cpuinfo processor : 0 model name : ARMv7 Processor rev 0 (v7l)Features : half thumb fastmult vfp edsp neon vfpv3 tls vfpd32 CPU implementer : 0x41 CPU architecture: 7 CPU variant : 0x3 CPU part : 0xc09 CPU revision : 0 processor : 1 model name : ARMv7 Processor rev 0 (v7l) Features : half thumb fastmult vfp edsp neon vfpv3 tls vfpd32 CPU implementer : 0x41 CPU architecture: 7 CPU variant : 0x3 CPU part : 0xc09 CPU revision : 0 Hardware : Xilinx Zynq Platform Revision : ffffffff Serial : 0000000000000000 root@zedboard-zynq7:~# TangoTest test1 Failed to import EventChannelFactory notifd/factory/zedboard-zynq7 from the Tango database Ready to accept request Edited 9 years ago Attachments: 779b 1Kb 930b 459b

Hi tangoers,

for those who need a customised linux distribution including tango, here is the successfull result of my attempt with OpenEmbedded & Poky. (no apt-get required)

It has been tested with a Zedboard (xilinx zynq fpga = dual arm7 cores) (TangoTest devices). I will give a try with raspberry pi 2 and BBB asap.

you need 4 recipes (zeromq omniorb4 tango)

hope it helps…

for beginners, more info here :
https://github.com/Xilinx/meta-xilinx
www.openembedded.org

attachments are omniorb4_4.1.7.bb, omniorb-native_4.1.7.bb, tango_8.1.2.bb, zeromq_3.2.5.bb 5

tango vdi for testing

those files are OpenEmbedded/bitbake recipes for tango, omniorb4, zmq.

OpenEmbedded is a collection of tools and recipes to build from scratch a linux embedded system.
it automatically download source code from repository, launch autoconf, cmake or anything else, then cross compile, build packages, … and generate a linux kernel, tailored for your hardware, modules, root filesystem, ext4, ext3, resiserfs, … even the bootloader

it is backed by TI,INTEL,ARM,… definitely the way to go with linux on embedded device

basically you have to install openembedded, then git clone some collections of recipes (meta : generics ones, meta-xilinx : xilinx specifics, …) edit local.conf to describe your hardware and software packages requirements (X11 or not, …)
eventually add some new recipes… It take a couple of hour (need a decent computer)… but very reliable

this is the tango recipes (easy because we use autoconf, bitbake knows what to do)

DESCRIPTION = "tango control system"

I will make you a demo next time smile

wnasimzada	Hi Raphael, could you please re-upload your VM? You posted a download link to other forums for a preconfigured VM but the zip-file (2,3 GB) is corrupted. Many thanks in advance! Wahid Best regards Wahid

raph38130	Sorry Whaid, I dont have access right now to my desktop. I will be back mid August. The last download link to VDI disk was : http://dl.free.fr/hrX7h9EMa Is it the corrupted one ? Rgds

wnasimzada	Hi Raphael, yes that's the link, I downloaded it again but I'm still not able to unpack the archive… It would be nice if you could upload it again when you are back :) Many Thanks, Wahid Best regards Wahid

raph38130	try this link http://dl.free.fr/nXmWNLGqM tell me if it is okay now … Edited 9 years ago

wnasimzada	Hi Raphael, now it works, thank you Best regards Wahid Edited 9 years ago

raph38130	maybe you have some time to write your requirements/advice in this thread about the new VM feel free to ask if you have specific needs… http://www.tango-controls.org/community/forums/topic/74/

wnasimzada	Hi! Do you maybe have some tips on how to use the recipes for open-embedded/yocto? I'm trying it since a week and it is still not working with the recipes. Is there a typo in the filename: omniorb4_4.1.7.bb instead of omniorb_4.1.7.bb ? I tested the VM and hoped your openembedded project was integrated and i could use it from your VM. I am working on a project where a controlsystem needs to be integrated on embedded devices like the zedboard (we're planing to develop a customized board with the Zynq Chip, but for now the Zedboard is more then we need for developing). The idea is, that we build a tailored os on the arm core running which is ready to use by plug'n'play in the control system, an automated subscription to the TangoHost / ServerIntegration is planed. Best regards Wahid
