No, we use sdkmanager installed JetPack
Sorry, I mean installing JetPack using sdkmanager. So in order to build the kernel for DTB and modules, an x86 host PC running on Ubuntu 16.04/18.04 is required, am I understanding this correctly? However, in the kernel customization documentation, it didn’t really mention a host PC is required. Could you clearify this?
Yes, sdkmanager need running on Ubutntu 16.04/18.04
Also if you have X86 host I would suggest compile the kernel DTB by it.
