Thanks,
The problem still persists after matching the proper fdt file name strings.

Thanks,

Hi,

From your boot log there is also:
reading uEnv.txt
864 bytes read in 4 ms (210.9 KiB/s)
Loaded env from uEnv.txt
Importing environment from mmc0 ...
Running uenvcmd ...

What is the content of uEnv.txt? Have in mind that this file overwrites the env settings done in ti_omap5_common.h

Best Regards,
Yordan

Thanks for the response.

Here is my latest log.
My uEnv.txt is empty! Like, am using the default image generated by running the script <SDK>/bin/create-sdcard.sh

Using the latest SDK ti-processor-sdk-linux-am57xx-evm-02.00.01.07

Please reply!

Hi,

Are you still using your custom am57xx_FG_EVM.dtb or do you use modified am57xx-evm.dtb (or am57xx-beagle-x15.dtb)? I am asking because I see you've set your fdtfile=undefined, & you haven't added am57xx_FG_EVM.dtb in findfdt variable.

Also on a couple of places in your log, you have:
omap_hwmod: l3_main_2 using broken dt data from ocp
omap_hwmod: tptc0 using broken dt data from edma-controller
omap_hwmod: tptc1 using broken dt data from edma-controller

And then your kernel panics. I still suspect that this is related to incorrect dts setting.

Best Regards,
Yordan
