Hi! Yea i was super pissed it didnt work. i ended up buying another one too on amazon and i bricked that one too. I said fudge it, returned both of them, and found the official jetson nano on ebay for 100$. The memory card here worked INSTANTLY. Seeed studio is an absolute joke. I’m actually right in the middle of working on my project right now on my official jetson, and its going very smoothly. You should contact them and return it if you can, its a shitty product. If you do plan on it, you should defintely get the official jetson from ebay. It’s SO worth it, and your time. So sad to see so many buyers going through the struggles we went through and having to end up getting screwed. Good luck my friend!
edit - Actually I just re read ur post and realized you already have the jetson, so you know full well that it works. Seeed studio is a scam
