I’m exploring the feasibility of writing production data in the EEPROM on the SOM.
When I look at Jetson EEPROM Layout — Jetson Linux<br/>Developer Guide 34.1 documentation I see this: “179–199 Reserved for future use.”
Can this area be used without compromising the current and future functionality of the SOM?
Are you using the devkit or custom board for AGX Orin?
What’s your Jetpack version in use?
Yes, you could write your custom data to the area not used by SOM.
Please make sure that you don’t overwrite the data especially the board ID/SKU…etc.
The devkit is used. Would it make a difference if it was custom board?
Jetpack isn’t used. A custom Linux build is done in Yocto.
Could the SOM be bricked if other areas are written to accidentally?
The data stored in EEPROM would be used during flash to know what’s the module in use.
If you’ve erased/modified the original data in EEPROM, you should specify the BOARDID/BOARDSKU/FAB in flash command and write the correct data back to EEPROM after boot up.
I would suggest you could backup the data in EEPROM in case there’s any wrong operation.
We don’t support yocto so that I’m not clear about the flash process for yocto.
