Jetson Nano booting at custom main board

Hi!
Help me please.
I’m making my own main board for Jetson nano. I make just UARTs, USBs and Ethernet at my board.
But now I have a trouble with booting. General mistake is Ram code = 2 in the log, I think. But what I can do for realize and shoot this mistake?
After booting I repeatedly send messages to UART ttyTHS1 and it’s working at nVidia developer board but unfortunately isn’t working at my custom board :(

My log:

Thank you!

Did you follow the adaptation and bring-up guide to change the device tree to match your carrier’s layout? Some pins on the modules have multiple possible functions, and some devices may route to alternate pins. Unless two carrier boards are exact matches in wiring layout, then the device tree will need to change.

Thank you for idea about adapt and bring-up guide. I will check it again.
When I was making the PCB I didn’t see any mistakes.

I saw only this info: Pull-ups or Pull-downs are present on the UART TX and RTS lines for RAM Code strapping.
And no more information unfortunately.
But which UART pins and what kind of pull are using for RAM Code strapping?
Where I can read about RAM Code differences?

Hi, pin 236 is for RAM code. Is there any device such as level shift on it? If so, better to use same level shift as reference design, also you can see a note in OEM DG: If level shifter is implemented, pull-up is required on the RXD line on the non-Jetson Nano side of the level shifter. This is required to keep the input from floating and toggling when no device is connected to the debug UART.

Thank you for answer!
I resolved problem with RamCode. There was problem with supervisor at my custom board and I received Jetson pmic max77620 NVERC : 0xff code and after it there was already RamCode = 2. I changed my supervisor and pmic max77620 NVERC code was change from 0xff to correct 0x40 and RamCode from 2 to 0.

But now I have a problem with Jetson UART1 (THS1). It works at nVidia dev board but not works at my board. I see the oscillogram and there is just +1.8V level at it.
In log files differences are:
At my custom board:

[0002.070] pm_ids_update: pm id update successful
[0002.074] pm_ids_update: Updating 3,ae, size 256, type 0

[0002.131] pm_ids_update: pm id update successful

Can it blocks the UARTs?
I think this log is becouse there isn’t i2c eeprom at my board like AT24C02D-MAHM-T (U11) at dev board? Please tell me how can I start UARTs at my custom board without i2c eeprom on board?

If I should change some boot properties please tell me how. At my custom board I want to use only UART0, UART1, Ethernet, USB0 and USB1.
How can I see my device tree? And should I change it?

I am unable to tell you what changes you may need, but if you want to examine the current device tree, then you can extract this from the running system (if you need dtc, then “sudo apt-get install device-tree-compiler”):

dtc -I fs -O dts -o extracted.dts /proc/device-tree
  1. Missing the eeprom “on carrier board” would not cause problem. However, if i2c fails to read the eeprom “on module” then it cannot boot.

  2. Please refer to adaptation guide on download center to usb bring up.

Why Jetson nano writes in log that hdmi cable connected?
When HDMI_HPD (pin 96) is pull up to 1.8V or down to GND there is not any differences! Every time I see the “hdmi cable connected” in my log. WHY???
In general is it possible to start Jetson nano at custom board??? I make many custom boards for different one-board PCs but Jetson is most NOT userfriendly platform unfourtunately(

I was read all your documentation and wasnt found any information about my problems!!!

Please give me information, sequence, step by step. What should I do if I want to start Jetson nano at my custom board.
Firstly I check my hardware and there an’t any mismatches from your adaptation and bring-up guide.
Next I should correct boot properties for my hardware, right?
For example in your documentation is the text “For the sample Ubuntu root filesystem provided by NVIDIA, this customization is applied using the script Linux_for_Tegra/apply_binaries.sh”
But which soft should I use for changing the script? Where is the folder Linux_for_Tegra?
I can’t find any fully information about it and it’s really big problem for me.

Hi,

Please don’t panic. It is common to hit issue when developing custom carrier board for embedded devices. There are many possibilities and many kinds of problems, so there is no document for it.

Please share your current dmesg with us and tell us what is the problem you have.

Also, some of the knowledge here may not be specific to tegra or nvidia driver itself. They are framework from Linux.

But which soft should I use for changing the script? Where is the folder Linux_for_Tegra?
I can’t find any fully information about it and it’s really big problem for me.

Linux_for_Tegra is installed on your host pc after your first installation from sdkmanager.

Note that the system’s idea of what hardware is present is likely due to the device tree. If you lack that hardware, then the device tree needs to disable that function.
