How can I activate my SD Card slot on Jetson Nano B01


I couldnt find a description to activate the SD card slot. I had to flash my Jetson Nano over SDK Manager and use now the 16 Gb emmc storage. Now I need more Storage and plugged my SD card which didnt work and reconized that I have to modify the device tree file.

Do have someone a clear description or can someone tell me how I do that ?

Thanks for your replys

Please search “mmc3” in jetson nano forum first.

Thanks @WayneWWW ,

I read some forums but couldnt understand some steps and couldnt reply because of closed dialogues. I am at the beginning and bought the wrong Developer Kit from Waveshare. It is not so beginner friendly and it is frustrating that I have to modify the hole system to run a SD card.

I found a description from waveshare. could you help me by step 2 “Install Image on TF Card” how can I get to that path.

I tried it with out recovery mode but it doesnt work.


What path do you want to know here? Also, what did you try?

Could you try to state your exact problem clearly?

Hi @WayneWWW ,

I want flash the dtb data with my ubuntu VM but I dont know how to go to the driectory :
cd ~/nvidia/nvidia_sdk/JetPack_4.6_Linux_JETSON_NANO_TARGETS/Linux_for_Tegra/kernel/dtb.
I have just the sdk manager and the image data form nvidia site Getting Started With Jetson Nano Developer Kit | NVIDIA Developer

I connected my jetson in recovery and see it with lsusb but cant figure out the directory.

  1. VM is not able to run sdkmanager well… because usb connection/detection may have problem.

  2. /nvidia/nvidia_sdk/JetPack_4.6_Linux_JETSON_NANO_TARGETS is the folder sdkmanger will help install to your host.
