Hi guys,

When I execute "ums 1 mmc 0" for downloading kernel image and dtb without entering uuu, the device always doesn't reset cpu and doesn't enter UMS mode.

Is this known issue on kernel 4.14.89-2.3.x? and do you have any idea to download kernel image and dtb without uuu?

Thanks in advance,

Hi Yibeom

 

kernel 4.14.98-2.3.0 is very old kernel not more supported, recommended to migrate

to latest releases    https://www.nxp.com/design/software/embedded-software/i-mx-software/embedded-linux-for-i-mx-applicat...

Options for downloading image can be found in Linux Guide included in  Documentation

Hi igorpadykov,

Thank you for answering.

I understand your comment, but i should keep kernel version to 4.14.98.2.3.x.

Do you have any patch to enable ums in kernel 4.14.98.2.3.x?

Thanks in advance

as workaround one can try with atf from release L4.14.78 (rel_imx_4.14.98_2.0.0_ga + rel_imx_4.14.78_1.0.0_ga atf )
