imx6ul not supprted in imx_4.1.15_2.0.0_ga

[mihaitaivascu]

Hello,

    It seems that imx6ul architecture is not supported in 4.1.15 nxp kernel even though it says it does. 

    Either that or the support is incomplete and patches for the imx6ul cpu, freq etc are needed.

    I could not boot my imx6ul with the 4.1.15-2.0.0_ga kernel. It halts at "Starting kernel in secure mode" and from my past experiences it means most likely  that imx6ul cpu specific configuration is missing in the kernel.

    Could you please confirm this or not?

Thanks,

      Mihaita

Hello,

  Have You tried the demo image for i.MX 6UL EVK?

https://www.nxp.com/webapp/Download?colCode=L4.1.15_2.0.0_iMX6UL&appType=license&location=null&Paren...

Have a great day,
Yuri

Hello,

    I work with FIT images (.itb) . I have tried both zimage files in that link and replaced in my build and rebuild my FIT image but the issue remains. If the kernel(zImage) would have been good I would have expected to see some additional output on my console.

    Is there anybody out there who successfully used the 4.1.15 kernel from NXP on imx6ul platforms?

Thanks,

      Mihaita

Hello,

    I was to mke further steps by changing some device tree settings but  the botting is not successful.

    I have attached a log. It halts at "Populating dev cache" message.
