Hi Jerry,
the i2c errors are from our custom driver as i told you. this happens because the camera we use is not conected. but this is no problem. I just posted the log from the working module for information about the version of the kernel and stuff we use… but the important error is in the log from the board that does not boot.
With Development Version i mean the Jetson Nano Development Board (B01) (SD-Card) and with Production Version I mean the Jetson Nano Production Module (emmc). Both of them we mounted on our own carrier board. I dont know all the diffrences between the two Jetson Modules. that is why im asking.
So again:

after the last print you see the Module stops booting and printing. Main deiffrence I notice is that the working Jetson Nano development Version has a Number of Blocks:
[0000.398] Csd NumOfBlocks=62333952
and the not working production module has 0:
[0000.478] Csd NumOfBlocks=0
can you tell me what this means?
