Hello , I just bought the SparkFun jetbot kit v 3.0. All went fine but when I try to boot up the bot from sd card (my board is j101 Emmc from seed studio but SeedStudio provides a tutorial to boot from sd) , I can’t get to the desktop. The oled screen shows up all the information and the strange thing is that it shows that the sd card provided (64G) only has 21G. I managed to allocate the other 40G but the boot still doesn’t go on giving failed to start nvpmodel service and then getting stuck on started daily apt upgrade and clean activities. After first boot try It only gives a lot of 12c acknowledge errors. Can someone help me?
Try using the seeed image 1st, get that to boot from SD…afterward I would then switch to trying to boot our image from SD
(you might have to load an image with jetpack 4.3 on it, install 4.3 and test
…then upgrade to a 4.4 or later image if needed)
I already did that and managed to boot jetpack 4.6 but not the jetbot image. I’ll now try to first boot a 4.3 jetpack and than boot the jetbot image, maybe that’s the problem; I’ll keep you updated.
I tried to do so. I managed to flash and boot Emmc to boot jetpack 4.3 but now it's impossible to follow the guide provided by seed studio to boot from sd, because I can't use Jetson-io.py to make the board recognize the sd card. Is there any way to have a jetpack 4.6 image for the bot?TS-Russell:

(I link the guide to boot from sd here: https://wiki.seeedstudio.com/Flash_System_on_SD_card/
Now that 4.3 is working, install any 4.4 or later image and it should work…it’s a long story 
I managed to boot 4.3 on emmc but can’t boot it from sd card. Can you explain what you mean?
Really sorry for bothering 
If can help I managed to run successfully the nvidia jetbot 4.5 image (as it seems 4.6 and 4.5 bootloaders are not so different so that works fine) ; can i just add sparkfun’s modifications from there? If yes, how?
I doubt anyone at sparkfun has used the seeed board. You might try asking seeed for assistance with their carrier board or switch to the same nvidia carrier board sparkfun uses in their kits.
Otherwise you’re kind of in new territory that nobody else has been in before and might have to figure it out on your own.
because of the overpricing that jetson nano is experiencing i think i’ll explore this land 
For the ones interested. I found out that in headless mode (so connecting the bot to a pc and using the ip 192.168.55.1) you can access to the jupyter site (even if booting gives some kinds of errors and doesn’t show desktop). So because of these errors that may give some kinds of problems (not sure) what I’m doing is: downloading the official jetbot 4.5 image, booting it from an usb (that doesn’t give errors) and then apply the software modifications that are on sparkfun site. Unfortunately i found out that using this method the board doesn’t recognise wifi dongles so ethernet is needed. I’ll do an update post once i figured this all out.
Here’s the update: I managed to do that but when running scripts from jupyter it gives a lot of errors as I read due to an outdated version of a library on the notebooks. Actually don’t know what to do.
