Getting Started/Flashing Guidance #113

Hi, Thanks for sharing this project!

I'm just getting started with the TX2 so apologies for the newbie questions. I have experience with Yocto but none with the TX2.

I wanted to understand the effort required to build my own Yocto based distribution instead of the Ubuntu based one installed with the Jetpack installer from Nvidia.

I can pull in this layer to my yocto build, change the MACHINE in local.conf to MACHINE ??= "jetson-tx2" When I do this, I'm able to build some deployment images in build/tmp/deploy/images/jetson-tx2 including rootfs and .bin files with bitbake core-image-minimal. However it's not clear to me how I could flash these to the board using the ./flash.sh or similar script from the Nvidia Jetpack installer.

I see some comments about tegraflash image types in #29 and a reference to IMAGE_CLASSES += "image_types_tegra" IMAGE_FSTYPES = "tegraflash" When I add this I see an additional tegraflash.zip file in the deploy directory, but it’s still not obvious how I can flash this on the part.

I'm guessing this is something which is obvious to folks who are more experienced with the platform and probably documented somewhere I haven't found yet. Any pointers would be helpful.

Thanks! Dan

Check out the wiki page on this topic, hopefully that will help.

Doh! Yep that's what I was looking for. I'd suggest a link from the README page although it looks like I was the first one who didn't find it on my own. Sorry about that.
