Eeprom

Linux_for_Tegra/bootloader/t186ref/BCT/tegra234-mb2-bct-misc-p3767-0000.dts
Configure the eeprom
cvb_eeprom_read_size = <0x100>
instead
cvb_eeprom_read_size = <0x0>
What is the meaning of this configuration in this path? Is there any documentation for this eeprom? I found that many companies out of the self-developed bottom plate flashing machine need to change here to flashing the machine,

Hi 77097962,

Are you using the devkit or custom board for Orin NX?
What’s your Jetpack version in use?

If you don’t have EEPROM on the carrier board, you would need to configure cvb_eeprom_read_size to 0x0.
For more EEPROM details, you could refer to the following instruction.
Jetson EEPROM Layout — Jetson Linux Developer Guide documentation (nvidia.com)

custom board,35.4.1和35.3.1

因為底板上的EEPROM通常只有NVIDIA的DevKit會用到,第三方廠商做的carrier board不會加上EEPROM,如果沒有EEPROM又沒把read size調成0的話開機的時候就會讀不到資料然後卡住

好的,谢谢

Check the path file. Is this file in this path?

是的
請把cvb_eeprom_read_size設成0之後再重燒一次

是设成<0>, 还是<0x0> ?

16進位所以是<0x0>

ORIN NANO 和 orin nx 都是修改这个参数是吗?

Yes, Orin Nano and NX have the similar design.
