When installing the JetPack on several boards, is there a command to just install the image to a board rather than go through the download etc.?
You don’t have to generate a new image each time, you can re-use an image and speed things up. However, I don’t believe there is any kind of “multicast” style support to flash more than one Jetson at the same time. In flash.sh the “-r” option will re-use the existing system.img without the time required to create it again.
after you finish the installation through JetPack, it would download the generated image and necessary tools under your JetPack folder.
for example, you should found the flash.sh at below path.
you could put the device in forced-recovery mode and using below commands to flash the image with existing system.img for TX2
sudo ./flash.sh -r jetson-tx2 mmcblk0p1
