Hi,

The dtb should be put under Linux_for_Tegra/kernel/dtb.

27

Thanks for reply
but it was not effect anything

28

What was the result under /proc/device-tree?

29

i changed sor1 DP port as mentioned

30

Could you add arbitrary string (e.g. your name) in dts and see if it take effect?

31

what it means?

32

Add something like “1234567” or “jaejun.sim” under the dts.
Flash it to the board and see if this string can be seen under /proc/device-tree.

If you can see it, it means the flash is working and there is something else make your dp still disabled.

33

Do you mean like this?

Yes, “test11111;” should be fine.
No need that “{}”.

35

it does not color if i remove “{}”

Hi

Could you share your dtb file here? I want to flash it to my device and see what is going one.

Also, what is the software release you are using? jp4.4.1?
