I have a photon carrier board from connect tech with an NX. I’ve been trying to flash to SD card for the last week but, as soon as I power cycle after a seemingly successful install. the system doesnt come back up.
I have attached a log of the first and second boot up to see if there are any clues. One major issue is it says there is no SD for some reason.
first and second boot.txt (94.9 KB)
ConnectTech have supplied a Board Service Pack which has been installed in the Linux_for_tegra which all worked fine when i was previously using the built in nx memory.
I have tried two different SD cards and formated it as ext4 mostly but sometimes ive tried Fat32. ConnectTech provide a script that should prepare things for booting from an external device. No errors were shown and I verified that the UUID was copied and that the rootfs folder structure was present on the SD and looked the same as that in Linux_for_tegra.
A couple other areas where I noticed something that might not be correct: After preparing the SD card, I noticed that I can mount it using mount /dev/sdc1 /mnt/cti but the SD card is not seen. If I try and mount it using mount /dev/sdc /mnt/cti i get a wrongfs error. I can use disks or gparted and it mounts fine so I’m not sure if there is a problem there.
During the configuration process on the NX, i noticed that after the hardware configuration progress bar there is a copying build progress bar but this always remains at zero and is skipped. Perhaps because the SD card isn’t found?
I have seen on the forum that etcher should be used to copy and image onto the SD. However, presumably I shouldnt be loading the NX developer image if im using a custom carrier board?
