Issue in powering Jetson TX1 using LiPO battery #16

Closed Aniket-Gujarathi closed 4 years ago

Aniket-Gujarathi commented 4 years ago

Tried to power the Jetson TX1 using 3S LiPO battery with output voltage of around 11V, but the jetson is not able to boot.

  1. According to link we tried to change the value of critical_current_limit0 by:

    echo 4000 > critical_current_limit0 However, after rebooting jetson, the values revert to the initial default value.

  2. According to some forums we attached a 4000uF capacitor across the input. But, even this didn't work out.

I have gone through some forums and also have talked with few people. I come to a conclusion that we should boost the 3s supply to 19v and then provide to Jetson. Also we need to check current on dc supply.

Attaching battery via a switch and other circuitry were limiting the current, which was causing the problem in booting Jetson. I have attached the DC power jack of jetson directly to the 3S LiPo battery, which solved the problem.

@YogeshPhalak Is that safe? Also, I think we need some capacitors to hold up the terminal voltage in case of brownouts (as Kamat sir had suggested earlier).
