About dtb compatibility between jetpack4.6.2 and jetpack5.0.1

Hello,

Can the dtb built in jetpack4.6.2 and earlier versions not be applied in jetpack5.0.1?
I was using the sd card slot with good activation, but when I designate the dtb built in jetpack4.6 in jetpack5.0.1 as FDT in extlinux.conf, the screen does not appear.

Thank you.

No able to work in jp5.0.1. Kernel version has been updated.

Hello, @WayneWWW

I am trying to modify the kernel source of jetpack5.0.1 to activate the sdcard.
I don’t know which folder to edit the source in: galen, galen-industrial, or jakku. Can you let me know?
I think it was jakku in the previous version, but I’m confused because more has been added.

And in jetpack5.0.1, extlinux.conf contains a part that specifies dtb as FDT by default. I don’t think this was the case in the previous version, is that correct?

manager@manager-desktop:/boot/extlinux$ cat extlinux.conf
TIMEOUT 30
DEFAULT primary

MENU TITLE L4T boot options

LABEL primary
      MENU LABEL primary kernel
      LINUX /boot/Image
      **FDT** /boot/dtb/kernel_tegra194-p3668-0001-p3509-0000.dtb
      INITRD /boot/initrd
      APPEND ${cbootargs} root=/dev/mmcblk0p1 rw rootwait rootfstype=ext4 console=ttyTCU0,115200n8 console=tty0 fbcon=map:0 net.ifnames=0

The modified files and contents are as follows, and dmesg after applying dtb to the jetson emmc module is attached.

Thank you.

  1. It is still Jakku. Galen is for AGX.

  2. And in jetpack5.0.1, extlinux.conf contains a part that specifies dtb as FDT by default. I don’t think this was the case in the previous version, is that correct?

I don’t know you and your board. You better sharing the schematic and full dts converted back from dtb.

Not sharing me a small screenshot.
