Jetson Orin NX not booting on custom carrier board

[aprasad1]

We recently flashed the Jetson 6.1 version using SDK Manager on the Orin standalone carrier board and successfully booted the device. However, after connecting the SSD and SOM to our custom carrier board (which lacks an EEPROM), the device fails to boot.

To resolve this, we referred to the following document: Jetson Module Adaptation and Bring-Up Guide (JetsonModuleAdaptationAndBringUp/JetsonOrinNxNanoSeries.html), and implemented the following modifications:

1. Generated pinmux.dtsi, gpio.dtsi, and padvoltage.dtsi files, in which we disabled the I2C-2 pins. These files were passed into the jetson-orin-nano-devkit-nvme.conf.
2. Modified the tegra234-mb2-bct-misc-p3767-0000.dts file by setting cvm_eeprom_read_size = <0x0>;.

Despite these changes, the issue persists, We are getting following Error

Command that we used for flashing:

Could you please review our approach and suggest any additional steps or corrections to ensure successful booting on our custom carrier board?

Looking forward to your guidance.

Hi,

• Please record the serial console log during the flash and attach it wit us.

Hi @DavidDDD,

I’m responding on behalf of @aprasad1 regarding this issue.

We couldn’t find any logs in the serial debug console, but we’ve attached the error logs generated by Jetson’s SDK Manager while attempting to flash JetPack 6.1 on our custom carrier board.

SDKM_logs_JetPack_6.1_(rev._1)_Linux_for_Jetson_Orin_NX_16GB_2025-01-16_12-26-59.zip (407.0 KB)

Could you review the logs and see if they provide any insights to help us debug or resolve this issue? Thanks!

Hi David,

We haven’t seen any messages on the serial debugger console yet. The main issue we’re facing is with flashing the firmware itself. Once the flashing process is successful, we hope to see the debug messages on the console.

Could you please check the logs we’ve received during flashing using SDK Manager? We’re awaiting your response and would appreciate any updates. Let me know if you need any further information from our side.

Thank you!
