The problem that when I download the JetPack and check the /nvidia_sdk/JetPack_Linux/Linux_for_Tegra/kernel/dtb , I found only the tegra194-p2888-0001-p2822-0000.dtb
and not the BPMPFW DTB file. Please, is there any update that I could miss it to flash the AGX board? or a new document?
bpmp dtb is not in kernel/dtb. go to check bootloader folder.
Is this your first time using this host to flash jetpack? Does " $ sdkmanager --archivedversions" show you the version or not? If it does not, could you confirm if you are using ubuntu20.04? 20.04 does not support old jeptack releases.
Where is the file `tegra194-a02-bpmp-p2888-a04.dtb on HDD AGX XAVIER, v4.6.1 ?
Can you write, the file is in /rep1/rep2/rep3/tegra194-a02-bpmp-p2888-a04.dtb, please.
I search all of HDD, not find tegra194-a02-bpmp-p2888-a04.dtb.
Perhaps is a another file name.
As I found the file tegra194-p2888-0001-p2822-0000.dtb rename kernel_tegra194-p2888-0001-p2822-0000.dtb in the target, I thought that the bpmp file was also renamed in the target, at the first installation.
Last question: to flash these two files, we don’t need a host, can you confirm?
No… the bpmp dtb and kernel dtb are two different things. It is not “rename” … these files are different. You can only find the bpmp dtb on the host.
And You need the host to flash…
You must prepare a ubuntu x86 host if you want to develop over jetson agx xavier… It would have a lots of tricks to prevent the host side work, but those would not just make you totally no need a host…
Honestly, I feel you are a newbie to the whole system. So better following the official method to play around those flash tools first.
Also, you should figure out the release you want to use… you cannot refer to a rel-34.x document while you want to use rel-32.6 BSP.
Rel-34/35 and rel-32 have large gap in the whole firmare.
My sequence (on host ubuntu18.04) :
1- take the x2 .dtb files in Jetson_Linux_R32.6.1_aarch64.tbz
2- Modify for the clock (PLL) for the CAN
3- Flash the files in eMMC.
I asked to know the names of the files that correspond to my card.
Yes, so flash the board first without changing anything and read the flash log to find out which bpmp dtb is in use.
Is it okay to understand this comment?
The file name would be varied with different board/sku so it is not possible to directly tell you “oh it must be xxx-bpmp-xxx.dtb”. You can use the flash log to find the answer.
