Hi guys!. hope you are doing ok. I have this jetson nano, I was able to flash the OS using the EMMC, but after booting the SD card is not being recognize. I suspect of the device tree file, but even enabling the sdhci@700b0400 which is the sdcard reader. still no luck. I’m using https://developer…

Dts files are in the “hardware” directory. Not in k4.9

Thanks for your reply Wayne. so If I understand this. I need to download the kernel sources make some changes on the dts file and recompile the kernel? is that so?

ok, one more question. can I use the source_sync.sh script in order to download the kernel sources? or should I do something different?

Use the tarball from our download center or source_sync.sh should be both fine.

I coudn’t find the sourcer for 4.9 kernel?

Then just use the tarball. [image] Jetson Download Center

After downloading the source code for 4.9 I got confused about where to found the dts file to modify, there is no tegra210-p3448-0002-p3449-0000-b00.dts file.

thanks a lot, I was kind of lost over the directory tree but I think I got it now. :)
