Jetson Nano module not working on custom carrier board

Autonomous Machines Jetson & Embedded Systems Jetson Nano
1

I’ve looked at all the available docs for the Jetson Nano Devkit and even the accessible 3rd party designs (GitHub - antmicro/jetson-nano-baseboard: Antmicro's open hardware baseboard for the NVIDIA Jetson Nano, TX2 NX and Xavier NX), but I still cannot get the Nano working on my custom designed carrier board.

Based on the available designs and docs, I believe the Nano only needs GND and 5V for the specified pins and 5V to the POWER_EN pin and it should work right away (since the other management pins are pulled-up/down internally). I measure the correct voltage levels on these pins btw (1.8V on SYS_RST*, 5V on SHUTDOWN_REQ etc.)

The Nano works just fine when I insert it into the Devkit (I wrote a script that starts automatically and toggles a GPIO), but it doesn’t do anything on my board.I use the same power supply for both carrier boards, so that shouldn’t be an issue. I also measured the current consumption, and I experienced the following pattern with the official devkit: 0mA → ~300mA → ~900mA → ~250mA (normal operation), but on my design, it doesn’t go above 300mA that makes me believe it cannot finish it’s booting process (or whatever normal sequence).

Is there anything I missed that is crucial for the Nano to turn on as expected?

Any help is much appreciated!

Hi, not sure about the difference between your design and reference, but POWER_EN should be enabled after the
carrier board has ensured the main supply is stable and the associated decoupling capacitors have charged.

3

Trumany,

That is insured, in fact, I pull the POWER_EN high only seconds after the main power, but it doesn’t boot up properly (I can’t even see any boot logs on the sdcard)

Besides that, can you assure me that the Nano only needs 5V, GND and POWER_EN (while the other pins are left floating) to turn on?

Thank you so much for you help!

4

Yes, basically that is enough for power on. Did you test manually pull up POWER_EN to high after 5V is stable? As you can see in reference schematic, there is buffer design from 5V enabled to POWER_EN enabled.

5

Yes, I’m doing the EN pullup manually.

6

Did you see power rails of carrier board up? Is there any log info output? If possible, can you share parts of the schematic for check?

7

Hi adam7wrsb,

Have you managed to get issue resolved? Any result can be shared?

8

Trumany and kayccc!

Your help is very much appreciated!
I uploaded the schematic and the PCB file here (Altium Designer files):
https://drive.google.com/open?id=1r1408VXe94Bj5FCTNba3lsY7ScTLlmg9

For confidential reasons, I removed the parts not related to my current problem. Just as a reminder: I’m trying to turn on the Nano on a completely empty board, only the 5V_JET line is connected to a 5V, 3A power supply (no components are placed), while pulling the PWR_EN pin high manually a couple of seconds after I connected the power supply.

Let me know if I can give you more details about the design.

9

See your POWER_EN is pulled up to 5V_JET directly, that might be the root cause, please refer to ref SCH to make sure the POWER_EN is enabled after 5V is really stable.

10

I know that, that’s why I tried to pull the POWER_EN pin high manually (avoiding the pull-up resistor with a jumper wire) only seconds after the 5V is stable.

11

Have you checked the UART txd pin for any activity during power up?

Have you checked the 5v supply rise time is within spec?

Check with CRO and post results.

Chances are it is starting up but it’s not happy with an external input, maybe even something simple like the Rxd pin is low and stopping boot process.

Good luck.

Peter, thanks for the reply!

I did a quick measurement. It really seems like some parts of the module is alive, but it doesn’t want to boot up to Ubuntu (I checked the boot log in the nvidia devboard but nothing is showing up there):


(5v supply has been provided 5 seconds prior to POWER_EN going high)

I’ve added the 3 recommended bypass capacitors to 5V and GND but nothing changed.

13

All,

Now I’m checking the serial debug output (UART2) and this is what I got for the first time:
https://i.imgur.com/W6kFcw3.png
(Left log is from a successful boot on the nvidia devkit, the right log is captured from my carrier board)

Some more tries, and the boot got even further. This is the first difference:

(Left log is from a successful boot on the nvidia devkit, the right log is captured from my carrier board)

And this is the conclusion:

(Left log is from a successful boot on the nvidia devkit, the right log is captured from my carrier board)]

And this is the full log, please check the last lines:

Hi Adam

Ok what might be happening is that you are using the Nano board that comes with your developers kit with your new custom board. Is this correct? If not then you can ignore the rest of my post.

The bad news is that you cannot use the developers kit board for your custom base board as there are approx 100 or so pins that are different!!! Yes believe it!! It sucks and it caught me out for a few days really.

You need to order production nano boards for your custom base board. It is the only way. The developers kit is useless and there are no schematics available for you to check this. The reference design schematics are a complete different kettle of fish.

It is quite stunning really that a custom board will boot at all somewhat with the dev kit board. Been there done that man. Oh what a time I had figuring this out.

Cheers.

In fact your log is saying exactly that.

You have:
Adding plugin-manager/ids/3448-0000-200=/i2c@7000c500:module@0x50

You should have:
[0001.994] Adding plugin-manager/ids/3448-0002-400=/i2c@7000c500:module@0x50

3448-0000-200 is the devkit nano module.
3448-0002-400 is the production nano module.

16

WOW, that is really…interesting…please tell me that this is highlighted somewhere in the official docs. Can someone from NVIDIA confirm this?

I have 1 question though, you are saying that some pins are different between the devkit and the production version, but the pinout looks the same in the
Devkit schematics:
https://developer.nvidia.com/embedded/dlc/Jetson-Nano-Carrier-Board-Reference-Design-Files
And in the Jetson Nano Product Design Guide:
https://developer.download.nvidia.com/assets/embedded/secure/jetson/Nano/docs/Jetson_Nano_Product_Design_Guide.pdf?afF-_Hr-B1hXLi67_MtmDGY6X7MwLaOhsBA_fJKLc7hqgrC6uwIEchnlFv4XZbR-CaATRuBKUGTYuyg1Soxd5M_qDYadRKU_P_Y7RiI76e0AwTeXrQgua3cnZugwJDpgb4lZ90ur9_Uv0OSjR8hxy-L5dXpH3-9TQYpareZVR_KSsIwKfuTwCizOyg

Yep but fear not so much. You have done the correct thing by following the reference schematic and the design guide. The schematic to the dev kit board has never been published so that apparently nobody gets confused but that only confused me like crazy really. They have great stuff but sometimes it’s difficult to find the info you need.

The reference board schematic is NOT the schematic to the dev kit carrier board.

I am certain that when you plug-in a production nano module that your new board is going to burst into a wonderful life! The design guide and reference design schematic have the correct pin outs for the production nano module.

18

Thanks peterxr95h it’s really helpfull. NVIDIA, can you confirm this information?

19

Current docs in DLC are for custom carrier board design of production module. Devkit is only for customer development not for product. There are some pin-out difference between two modules. Customer should design their own carrier board based on OEM DG and reference schematic in DLC.

20

hi,peter
Did every thing works well when you plugged the production nano module?
I found some mistakes/errors in Jetson nano Product design guide.eg:Figure 12:DP0_AUX_N 96 (actually 90)
Or the reference schematic is correct?
