Hello, We develop Real-Time OS called RedHawk which we are currently trying to port over to DRIVE AGX. During this process, the Xavier(s) need to be flashed regularly with updated kernel or bug-fixed kernel. On Xavier A, we run below command on the host system to flash the kernel partition: sudo …

Hello AnishAney, can you please specify the command you use to flash the kernel partition? also, can you share the log when executing the command?

Hello ShayNV, I ran the same command as I have for Xavier A, with variables changed from “A” to “B” and also board updated to “b”. sudo ./bootburn.sh -b e3550b03-t194b -u B_1_kernel B_1_kernel-dtb B_1_ramdisk -x /dev/ttyUSB3 The “out” directory’s entry shows imagepath has been changed to “/home/a…

Hi AnishAney. The -u option will be deprecated in the future. you could speed things up in a couple of ways: 1.) Use the -d option for replacing the dtb. See documentation : https://docs.nvidia.com/drive/drive_os_5.1.6.1L/nvvib_docs/index.html#page/DRIVE_OS_Linux_SDK_Development_Guide/Flashing%…

Hello shayNV, 1.) Will this option update the dtb partition for the Guest OS on Xavier B? Also, I have to mention other two partitions (kernel and ramdisk) along with kernel-dtb, otherwise “authentication group” failure error message occurs, and vice-versa. 2.) I tried to run the above command, bu…

Hi AnishAney, yes for both questions. right, sorry for that, this option will be available in future releases. option 1 will replace it. checking that in parallel. in the meantime, please try option 1 and update if this works for you.

Hi shayNV, Is there an option to update the kernel? We don’t need to update kernel-dtb and looking at the documentation, ‘-d’ option only updates only the kernel-dtb file.

Hi AnishAney, Can you go into the linux_storage_emmc.cfg and comment out or delete the following lines From: authentication_group=1 to: #authentication_group=1 Then reflash the whole image and then try the updated partitions. This should turn off authentication groups

Yes, I can give this a try, but since it doesn’t take much time to flash other partitions, it won’t make much difference. However, anything to get Xavier B’s kernel partition to be flashed quickly will be great!

@AnishAney @shayNV How did you solve it, I have the same proble. we run below command to update dtb: sudo ./bootburn.sh -b e3550b03-t194a -u B_1_kernel B_1_kernel-dtb B_1_ramdisk -x /dev/ttyUSB3 script return success,but xavier B still uses the old dtb. thanks

Hi @qichen.ou1 , Please create a new topic linked to this one. Thanks.
