Power On Self-Test for DDR4, EEPROM, etc. How is the hardware component self-test event being reported? It is normally performed prior to Kernel images load. Please advise. Thanks

Hi iewen.lee,

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

Do you mean some checkings in bootloader(UEFI)?

We use the Orin NX module plugged into the dev kit.

JetPack is the latest 6.0, if earlier version is required, please advise.

Also please advice how to obtain the POST self-test upon startup.

If any hardware failure (e.g. memory self-test on startup) failed, how is the detection event be made available for later stage of bootloading sequence?

Thanks again

Jetpack 6.0 DP is developer preview version rather than GA version.
I would suggest using the latest JP5 release with R35.5.0 in Jetpack 5.1.3.

I think there’s some self-checking in UEFI during boot up.
You could refer to Build without docker to build debug UEFI binary and check the logs in serial console to know what it did.
