Jetson Nano running very slowly

Robotics & Edge Computing Jetson & Embedded Systems Jetson Nano
1

I set up my Jetson Nano and it takes about 10 minutes to boot and runs very slowly afterwards.

I have tried using a few different power supplies and switched from a micro USB power supply to a barrel power supply, but the Nano’s performance has not changed. The barrel power supply provides a consistent voltage of just over 5V, so the power supply doesn’t seem to be the issue.

I have also tried switching to a 32GB micro SD card, but the Nano does not send a signal to the monitor when using this card. This monitor uses an HDMI to HDMI connector and I used it to set up the Nano using the smaller 16GB card, so the monitor should work.

I contacted the live chat to RMA the Nano and they suggested that I make a post here, so does anyone know of any possible solutions?

I start with 64 gigabytes of SD.
It 's probably still a power supply.
Did you do all the SD loading operations according to the instructions? I 've had problems before as I ignored the instruction.

3

Yes, I followed the Getting Started guide and wrote the image to the SD card according to the instructions.

We don’t have access to a 64GB micro SD card and this is for a school project that has a budget, so we want to avoid buying a larger card if it isn’t necessary.

4

It may also be related to unattended-upgrades. You may also check this post if you have very low internet bandwith and are aware of the security issues.

5

What is the maximum ampers of electricity supply current?

6

I have tried a 2A USB-C power supply, a 3A USB-C power supply, and a 3A barrel power supply. All of them work, but switching between them does not seem to affect the speed of the Nano.

7

Didn 't embed such powerful USB power supplies.
I think it 's easier to go to tech support. It 's by their part. I 'm sorry I can 't help you.

Hi,
Are you able to dump the serial log? We would like to check where does it hang for >10 mins during boot up.

9

I have my own experience.

  1. SD card speed is really important. My Jetson sometimes froze with a few SD cards. I don’t know why because that cards run in RPI3 almost year without issue. Also, Jetson sometimes looks like he froze. So you click on something you except activity but, nothing. You can click somewhere and then everything pop-up and run. It does matter if is it Python or LibreOffice or whatever. The solution is to move your system to SSD. So boot from SD and the rest of system is on SSD. Second tips are power.USB must have minimal 2A ideally 3A and you can still except, unexcepted shutdown because jetson doesn’t have enough power if you connect for example camera via USB.
    Latest point is a fan. He can help a lot.

I tried booting it up today, and now it is behaving differently. When I plug it in, it repeatedly reboots itself until I unplug it. Here is what appears in the log every time it tries to boot:

The bootloder log seems not have any problem. Only panic happens in keren.

May I know

  1. Do you hit this error in every boot up?
  2. Do you have only one jetson nano? Could you plug the same sdcard to another nano device and see if this issue also happens? (clarifying if this is hardware issue).
12

Yes, I hit this error every time the Jetson Nano tries to boot up.

I only have one Jetson Nano, but I do have another micro SD card that I have tried, if that helps. With the other SD card, the Jetson Nano does not boot and encounters this error:

evanmiller,

Are you always using sdcard image? Have you tried sdkmanager before?
Other users reporting that the sdcard image is more unstable than the driver package from sdkmanager.

I think you could try it too.

14

I have not tried using SDK Manager. I’m on a break right now, but I will try it next week when I am back at school.

15

Since I last posted, we were able to try our micro SD cards and power supplies with a different Jetson Nano and it behaved the same way. We also discovered that our 32GB micro SD card cannot be formatted and we tried using SDK Manager to set up our 16GB card, but the Jetson entered a similar loop where it would repeatedly reboot itself.

It seems to me like the micro SD cards are most likely causing the issues we’re having. We’re going to order a new 64GB micro SD card and see if it gives us better results.

16

Change a high speed SD card to solve this problem.

17

Switching to a different micro SD card fixed the issues. I’m still not entirely sure what was wrong with the cards I originally tried using, but the Jetson Nano runs at a much better speed using this new one.

Thanks for your help.

18

Just wondering what class of the micro SD Card did you changed? V10?
