    Hi John,

    Creator Platforms are MIPS development boards like the Ci20 and Ci40. https://community.imgtec.com/platforms/creator-ci40/

    Creating .pod files is not related to Ci20/Ci40 so the PowerVR section of the forum would be the best place to post.

    Does that make sense?

    Hi John,

    This section of the forum is for MIPS Creator platforms rather than PowerVR graphics. If you post in the PowerVR section https://community.imgtec.com/forums/cat/powervr-insider-graphics/ someone should be able to help you (hopefully!).

    Thanks,

    Matt

    Hi Amit,

    You can try 16 as well, but it’s not something we have been looking at in development or testing.

    What’s the motivation behind upping the page size? Are you seeing performance issues with 4?

    I’ll investigate your log and see if there is anything we can do to get it working.

    Regards,

    There is no compiler by default. gcc is currently a bit broken on OpenWrt (https://github.com/openwrt/packages/issues/2244) but it should be possible to make it work.

    1. enable gcc in ‘make menuconfig’
    2. Modify “staging_dir/target-mipsel_mips32_musl-1.1.11/pkginfo/libc.provides” to add libc.so.6, otherwise GCC will complain about missing dependencies
    3. Once on the Ci40, the following command can be used to compile:
    gcc -Wl,–dynamic-linker=/lib/ld-musl-mipsel-sf.so.1 <files>
    The dynamic linker needs to be explicitly provided, otherwise the resulting executable won’t run.

    It’s a bit of a workaround (and there are several ways to work around the problem), but hopefully that will work for you in the short term.

    Hi Nadeem,

    1. The source for U-Boot is not available yet. I’ll try to get an expected date for it’s release for you.
    2. We have sysupgrade available for updates, but you may need to update your bootloader first for this to work (depending on when you got your board). https://github.com/IMGCreator/openwrt#system-upgrade. All the different flash and upgrade mechanisms are described on that page.

    Thanks,

    Matt

    Hi Yasuhiko,

    It should have OpenWrt pre-installed (all production boards will have it flashed on). Your unit may be different, as it’s a pre-release. Try “run dualnandboot” in the bootloader terminal and see if you get the same result. If so, you will need to boot from USB or SD (https://github.com/IMGCreator/openwrt#boot-from-usb). You can then flash the NAND image if you would like to remove the need for additional storage devices.

    Regards,

    Matt

    Hi John,

    Ci20 uses a MIPS CPU so an i386 distribution won’t work – i386 is designed for 32-bit Intel processors. A list of distros for Ci20 can be found on elinux http://elinux.org/CI20_Distros.

    Hi Amit,

    We’re looking into what may have gone wrong, but it could be one of many different things. Could you please try following the instructions for flashing NAND from within OpenWrt (from the same document)? That page has been updated recently so be sure to refresh it if you have left it open. If you flash the partition from there and it still does not work, it points to it being a problem with the image itself rather than the NAND flash mechanism.

    Thanks,

    Matt

    Hi Amit,

    Which of the NAND flash methods did you use, was it in u-boot with USB/TFTP or did you flash from within OpenWrt?

    Thanks,

    It says in here that the factory default debian image does not have ssh, so you would need to install it with apt-get. If you have already installed it and it doesn’t work, are you able to tell us the exact error you see? Does your SSH client make a connection and fail to authenticate, or does it fail to make a connection in the first place?

    Hi Brian,

    I’ve just tried:

    ssh ci20@<IP ADDRESS>

    and then entered the password ‘ci20’ when prompted and it worked ok. This is using Debian 7 on Ci20 and an Ubuntu 14.04 laptop.

    Is this exactly what you have tried?

    The elinux page http://elinux.org/CI20_Headless_Setup has some more instructions on remotely accessing your board which may be helpful.

    Let us know if that helps. If not, any more information you can provide would be useful to help understand how your setup might be different to mine.

    Thanks,

    Matt

    Hi Yasuhiko,

    All the documentation exists, but Ci40 has not been released so it’s not publicised yet – this is why I assumed you might have a Ci20 (you aren’t on my list of “people with a Ci40”), and it explains why you can’t find any documentation. You should have been given details of this when you received a board from your contact in IMG. I apologise for the inconvenience.

    Our beta website is up at beta.imgcreator.io and this has beta docs linked from it that you can use to get started. It does not include everything, and is also focussed on the Creator Kit external trial we are currently running. Much of the process detailed there will change significantly (become much easier) before release of the boards + kits.

    Depending on when you got that board, it could have one of a number of software variants on it, or none at all. Your IMG contact should be able to give you details of what’s on the board. If the docs about connecting to the board over serial do not help, then let me know and we can find a route forward.

    Regards,

    Matt

    Hi Yasuhiko,

    I’ve not seen any output like this on a Ci40 board before. Are you able to give some more information on your set-up (what’s connected where, what software do you have on the board…)?

    Can you also confirm that you are using a Ci40 and not a Ci20? If it’s a Ci20, some information is available on elinux http://elinux.org/CI20_Beginners_Guide which gives instructions on how to set up without a display which may be useful to you.

    Please let us know how you get on.

    Matt
