Hi chengcheng2015,

Are you using the devkit or custom board for AGX Xavier Industrial module?

It seems you are porting a nor-flash module(from FUJITSU) controlled by SPI interface.
We don’t have this module to verify locally.
Have you also asked the help from your vendor?

Or is there any error showing in dmesg during boot up?

[    1.686823] m25p80 spi0.2: unrecognized JEDEC id bytes: ff, ff, ff

Please check your m25p80 driver and debug the above error.

Have you confirmed your nor-flash module connected correctly?
(eg. which pin you used for CS? why you configure it as fram@2 rather than fram@0 or fram@1?)
