Opkg repositories not accessible

Hi,

I'm new to using Angstrom and OPKG (which comes standard with the Arago distribution on AM572x EVM). I am trying to install some basic packages (e.g. nano editor etc) and I'm following the guidance given on the OpenWRT website [ https://wiki.openwrt.org/doc/packages ]. However, when I try to run `opkg update`, it throws the following error:

 

Collected errors:
* opkg_download: Failed to download gtautoftp.gt.design.ti.com/.../Packages.gz, wget returned 1.

I did opkg update many times, and even added some extra lines to /etc/opkg/opkg.conf and which the newly added downloads.openwrt.org repositories seem to work, the ones at TI seem to be inaccessible (I tried accessing them via browser and that too fails). Does anyone have any idea what I'm supposed to do? Am I missing something?

Thanks

    I will forward this to the software team. They will respond here.

    Hi Anshul,

    Which software release are you using? I am not familiar with an Angstrom distro for AM572x, is this a community release?
    Official AM572x EVM sdk is located here: www.ti.com/.../PROCESSOR-SDK-AM57X. This is Yocto distribution. Have in mind that OPKG repositories for AM572x SDK are very limited, basically if you need to install any package, you need to add it to the yocto build & rebuild the filesystem, see the following wikis:
    processors.wiki.ti.com/.../Processor_SDK_Building_The_SDK
    processors.wiki.ti.com/.../Processor_SDK_Linux_Filesystem

    Best Regards,
    Yordan

    Hi,

    Thank you for the reply. Maybe I have incomplete information and negligible experience with embedded Linux, but here are some details that might help shed some light on my problem and goals:

    I'm working on the  AM572x Evaluation Module and I believe I'm running the same distro it came with (i.e. I did not change it). A uname -a command yields the following output:

    Linux am57xx-evm 4.1.13-g8dc6617 #1 SMP PREEMPT Thu Jan 28 14:18:18 EST 2016 armv7l GNU/Linux

    I was not able to determine exactly which distribution this was from the output (lsb_release command doesn't work apparently, on this distro), until one of the TI employees on this forum mentioned it was the Arago distribution from TI, made for their board(s); some more digging gave me the impression it was forked from the OpenWRT and Yocto projects, which led me to believe this was an Angstrom distribution/Angstrom-style Linux. I was also told no other distros are supported by TI at the moment.

    Initially I wanted to change the distro to a desktop version of something I'm familiar with, e.g. Ubuntu ARM, or the Linaro ARM with desktops so that I can use the standard tools, e,g, aptitude etc to build third party packages that will help me interface AM572x EVM with external image and depth sensors etc. But apparently I cannot install any other distro unless TI provides h/w support for that (please correct me if I'm wrong on this).

    So I'm at the point where I'm trying to make do without the GUI/desktop that I'm used to on a Linux for PC/minicomputers. Thus I'm trying to learn opkg and installing third party libraries which might help me accelerate my development.

    Based on the information you gave me, I believe I have two options hereafter:

    1) Try to install a completely different Linux ARM distro (preferably with a desktop) so that I can work in familiar territory (please let me know if this is even possible).

    2) Make do with the Arago and try to get the sensors interfaced with the board somehow. Note that I will also need to cross compile OpenCV, OpenNI and some other third party libraries on the TI board for this to work.

    Thanks

    This is arago, and yes TI provides limited customer support for other distributions. However there is some community work for porting ubuntu on AM57xx, i.e.: elinux.org/BeagleBoardUbuntu. Note that some modifications may be needed for AM57xx EVM (I've not tested this myself..) and as I noted you will have to rely heavily on the beagleboard community.

    Best Regards,
