How can i flash using Linux?

Former Member

Hi,

 

there is no method described in the manual. I guess many (most?) people interested in an open

hardware development device are using linux.

 

I hope there are any tools available and the documentation can be extended.

 

Thanks

    Remember that the RIoT board is targeted specifically for Android development, not mainline linux.

     

    It's also not a truly open hardware design as the actual CAD files are not provided. There are Gerbers available now which allow you to produce an exact copy, but the Mentor/KiCad/Eagle/whatever source files are not available so you can't easily modify it.

    There are better choices if you want an open hardware board, for eaxmple the Olimex OLinuXino boards.

     

    However, the user manual has section 5 on how to build linux kernel images and you'll find a linux download on this page RIoTboard

    actually, I take it back.. the gerbers download that appeared the other week isn't really gerbers at all, it's PDFs of the gerbers and as such totally useless for building your own...

     

    The PDFs are of course helpful for examining the design, finding out where to cut tracks and such like, but nothing more. So even less of an open hardware design that I was thinking image

    Thanks for the reply. You are right - it's maybe not that open.

     

    I have seen the linux image. My problem is, that i don't see a way to upload it to the riotboards eMMc. The mfg tool is not

    running on my linux desktop.

    I don't have a board, but can't you just write it to an SD card and boot from that ?  Assuming the sizes work out it's probably possible to just dd the image to the eMMC afterwards.

     

    There's no real requirement for the mfgtools, but if you're stuck on doing it that way, you can try https://github.com/boundarydevices/imx_usb_loader which is what's used for other i.MX6 boards. I've used it successfully on sabre-lite

    We will be uploading the actual gerbers very soon - and it will be truly open source.

     

    Based on some of the community feedback, we are also looking into CAD library support with other tools.

     

    Thanks

    AFAIK you can only boot Linux from the internal eMMC — not from the external.

    Where did you get that information ?

    The user manual says otherwise (and other i.MX6 systems can boot from varying places)

    So once you set the boot switches to SD you can boot whatever you like from SD.

    Hi Vandana, that's very good to hear!

     

    I don't know what tools were used to produce the RIoT, but Eagle would seem to be a good choice of format for e14 to release the files in image

    It's on Page 44 of the UM that it mentions that Linux currently only boots from eMMC. Though maybe that means eventually it'll have an SD option. As you stated, the chip can boot from either interface, so it seems to be a software configuration thing for Linux.

    Hi,

     

    to get back to topic ...

     

    At the end i used an old windows notebook for uploading open source to open hardware.

    The result is nothing i would safely call open any more.

     

    Still looking for a linux solution. Of course linux as sd-card image would be perfect ;-)

     

    I had a look on imx_usb_loader, but i didn't got how to use it with the riotboard.
