# Jetson Xavier NX
###### tags: `Jetson Xavier NX`
## Nvidia jetpack 5.0以上版本特性
### NVIDIA jetpack docker image
* TensorRT Nvinfer需使用到host端資源**
* libnvmedia_tensor.so => not found
* libnvmedia_dla.so => not found
* 官方目前只提供jetpack 5.0以上版本image [[link]](https://catalog.ngc.nvidia.com/orgs/nvidia/containers/l4t-jetpack)
* 若要使用舊版建構l4t-base [[link]](https://catalog.ngc.nvidia.com/orgs/nvidia/containers/l4t-base)，需取得arm架構(cuda cudnn tensorrt) deb file
* 在舊有架構中(jetpack 5.0以下)，有機會拿到Nvidia不小心流出的arm64 deb檔，可直接原地升級(cuda cudnn tnesorrt),現有官網只提供ubuntu 20.04(jetpack 5.0以上板本)
### Jetson XavierNX
* 刷機教學
* [system is built on sd card](https://blog.csdn.net/zbb297918657/article/details/106390209)
* [system is built on emmc](https://blog.csdn.net/wjinjie/article/details/118295766)
* 需自備 jumper短路xavier 2個ping腳位, 進入recovery mode
* 安裝NVIDIA sdkmanger
* 系統轉移(emmc or sd card容量不足)
* Jetson Xavier NX上以SSD運行作業系統[[link]](https://blog.cavedu.com/2020/06/02/jetson-xavier-nx-ssd/)
* minicom -D /dev/ttyACM0 -8 -b 115200
