    I do not remember exactly as we only used it once, but I believe you can upload everything through MFG Tools (uboot & linux).

    This is just to give you an idea (from MFG tools config):
    Source: https://www.imx6rex.com/open-rex/sof...setup-mfgtool/
    -------------------------
    <LIST name="OpenRex-uBootOnly" desc="Only boot u-boot.imx">
    <CMD state="BootStrap" type="boot" body="BootStrap" file ="u-boot.imx" >Loading u-boot</CMD>
    <CMD state="BootStrap" type="load" file="firmware/fsl-image-mfgtool-initramfs-imx6qdlsolo.cpio.gz.u-boot" address="0x12C00000"
    loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" ifdev="MX6Q MX6D">Loading Initramfs.</CMD>
    <CMD state="BootStrap" type="load" file="firmware/fsl-image-mfgtool-initramfs-imx6qdlsolo.cpio.gz.u-boot" address="0x83800000"
    loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" ifdev="MX6SL MX6SX">Loading Initramfs.</CMD>
    <CMD state="BootStrap" type="jump" > Jumping to u-boot. </CMD>
    </LIST>

    -------------------------

    Notice /fsl-image-mfgtool-initramfs-imx6qdlsolo.cpio.gz.u-boot

    When you google for more info, you can find this: https://community.nxp.com/thread/470979

    Hope this helps.

    2) USB

    3) Yes (there is stresstester application what can be uploaded through MFG Tool https://www.imx6rex.com/software/how...ation-on-imx6/ ) - that is a basic test but should be good enough before running a proper Linux with for example stressapptest: https://www.imx6rex.com/software/str...stressapptest/

  • Uploading Linux into i.MX6 Rex module without Base Board !!

    I watched the Robert video ( Bringing up i.MX6 Rex Board to Life) in which he tested iMX6 Rex module without a Base board ! He uploaded the Linux into the module and then Linux was booting, so I have 3 questions:

    1. How does the Linux upload in the module that doesn’t have SD card and eMMC?

    2.What are the pins of module that allow us to upload Linux without a Base board?

    3.Would it be possible to test DDR memory without a Base board? if so, How would it be possible?
