How to flash image?

EOS-JNX

emmc image and microSD image are one-by-one mapping. That is, you have to flash emmc and microSD image with same version. For example, jetpack 5.0.2 emmc + jetpack 5.0.2 microSD image

Download eMMC image

[jetpack5.1.3 md5: 1203689de27fde2bc7151f27ff5b9e6e]((https://sftp.adlinktech.com/image/EOS-JNX/EOS-JNX_JP513_emmc.tar.gz)
jetpack5.0.2 md5: 588e91411bb61f5b95b190bebb8373de
jetpack4.6.1 md5: e9978a1f7d981b11fd9f323a6ca73aa7
jetpack4.6
jetpack4.5

How to reflash eMMC image

To perform this step the following equipment is required:
- A bare metal machine running Ubuntu. Must not be a virtual machine.
- microUSB cable
For Jetpack 5.0.2: Install neccessary package at first
```
sudo apt-get install sshpass
```

On the Host PC unzip the file downloaded.
```
tar -zxvf EOS-JNX_JP502_emmc.tar.gz
```
Set EOS-JNX as recovery mode
- Boot EOS-JNX
- Hold RECOVERY button on front panel
- Push RESET button on front panel
- Release RECOVERY button
Connect the microUSB cable to the EOS-JNX and the Host PC
Open a terminal and execute the lsusb command, to see if the NEON is connected. If a device called Nvidia Corp. is detected, the device has successfully entered recovery mode.
Go to folder unzipped in step 1

cd EOS-JNX_JP502_emmc

Flash the EOS-JNX

Jetpack before 5.0.2

sudo ./nvmflash.sh

For Jetpack 5.0.2

sudo ./tools/kernel_flash/l4t_initrd_flash.sh --flash-only --massflash 20

Once the flash script is complete and shows Flash complete (SUCCESS) reboot the EOS-JNX
