Jetson AGX Orin 32GB module busy spin on Custom Board

1.We have a Jetson Orin module. I’ve flashed the module with Jetson Linux 35.4.1 and it boots successfully on the dev kit. However when we put it on our custom board, the module show “Busy Spin”


E> I2C: slave not found in slaves.
E> I2C: Could not write 0 bytes to slave: 0x00ac with repeat start true.
E> I2C_DEV: Failed to send register address 0x00000000.
E> I2C_DEV: Could not read 256 registers of size 1 from slave 0xac at 0x00000000 via instance 0.
E> eeprom: Failed to read I2C slave device
C> Task 0x0 failed (err: 0x1f1e050d)
E> Top caller module: I2C_DEV, error module: I2C, reason: 0x0d, aux_info: 0x05
I> Busy Spin

My custom board does not have AT24C02D-MAHM-T
What is the function of this EEPROM?
How can I avoid this problem?

Orin module + custom board
NV_MY_D.log (19.5 KB)
Orin module + dev kit
NV_EVB_D.log (111.6 KB)

My board cannot enter Recovery mode

no USB device

Hi channinglan,

After putting the module on the custom board, please reflash the custom BSP package for the custom carrier board.

Do you press REC button(short with GND) and power up the board to enter force recovery state?

I refer to the following website to modify the EEPROM and it can boot successfully.
USE module

  • 7023 for Jetson AGX Orin (P3701-0000 Developer Kit module)

Also modify Linux_for_Tegra/bootloader/tegra234-mb2-bct-misc-p3767-0000.dts.

But change use

  • 7223 for Jetson AGX Orin (P3701-0004 with 32GB)
    can’t boot successfully

7023 for Jetson AGX Orin (P3701-0000 Developer Kit module)
7223 for Jetson AGX Orin (P3701-0004 with 32GB)
Is there any difference in compilation or burning between the two???

AGX Orin是P3701,你確定改P3767的檔案會有用?


I modify tegra234-mb2-bct-common.dtsi is ok

0325_EVB_7023.log (105.3 KB)
0325_EVB_7223.log (103.1 KB)

USB Custom Board
0325_CUSTOM_7023.log (91.7 KB)

but 7223 + custom board no any message …

基本上不會有 "沒有message"的狀況… 只有可能是你沒抓到log的狀況 或是你板子有問題.

另外如果原本的busyspin問題已經沒了 請你針對新問題開新的topic.
