The wrong boot authentication identification

Hi,

This is yet another follow up post from Boot failure after nvmflash.sh.

I have been very comfortable for burning fuses and executing mfi to flash a pre-built image with our PKC.

But I found I can not extract an image of a particular partition (APP) with the flash.sh command anymore.

$ sudo BOARDID=3448 FAB=200 BOARDSKU=0002 ./flash.sh -r -k APP -G ../nano_r32.3.1_original.img -u '/l4tpool/l4timages/emi_pkc_nano.pem'  jetson-nano-emmc mmcblk0p1

Error: either RSA key file and/or SBK key file are proviced for none SBK and PKC protected target board.

As you can see, the Boot Authentication is recognized as NS. But it is actually PKC as follows.

It was the same condition before I had enabled the odm_production_mode.

The secureboot on this box is correctly enabled?

Is there any way to fix this situation to extract an image?
If not, I am going to create our own image on a non-PKC protected device.

Thanks!

I found this doesn’t work, either.

This is actually the same result when I tried to run this command against the box above with PKC (but recognized as NS).

Then, I found a patch provided in this post, About the making of the mirror of the Jetson-nano module, then am successfully gettting an image (very slowly…).

Hi,
Please check

If there is follow-up questions, please let us know.

Now that it became clear that pkc_disable is correct, 0x1, but flash.sh does not work so. I think that’s why I get an error Error: either RSA key file and/or SBK key file are proviced for none SBK and PKC protected target board. as shown in the first post. Can you confirm this?

For the second post without PKC, I am able to backup an image with the patch. As a workaround, I work on a non-PKC box to build images, and each of which is backed up and used to create a mfi file.

So, it is fine for now, not urgent.

Hi,
Your understanding is correct. Please look at code in flash.sh

	NS)
		if [ "${keyfile}" != "" ] || [ "${sbk_keyfile}" != "" ]; then
			echo -n "Error: either RSA key file and/or SBK key file ";
			echo "are proviced for none SBK and PKC protected target board.";
			exit 1;
		fi;
		;;

I see. Then, flash.sh won’t work correctly if PKC is enabled (pkc_disabled = 0x1) because the script misunderstands it is NS. I hope this would be fixed in the next release.

Hi,
flash.sh is correct since pkc_disable=0x1 is NS. For enabling secureboot, you need to have -c PKC -p -k …/emi_pkc.pem so that pkc_disable keep 0x0. If you have -c PKC -k …/emi_pkc.pem(no -p), pkc_disable is burned to 0x1 and no longer returns to PKC mode forever.

Oh, I see. So, any test attempt without -p burns 0x1 on pkc_disable. So I should have burned all the fuses in a single step! Now I got it clearer.

I have finally tried burning fuses with a single command with -p. But then, mfi won’t succeed as follows.

Burning fuses.

*** Mass Flashing tarball mfi_jetson-nano-emmc.tbz2 is ready.
********************************************************************************
    1. Download mfi_jetson-nano-emmc.tbz2 to each flashing hosts.
    2. Untar mfi_jetson-nano-emmc.tbz2. ( tar xvjf mfi_jetson-nano-emmc.tbz2 )
    3. cd mfi_jetson-nano-emmc
    4. Connect Jetson boards(jetson-nano-emmc only) and put them in RCM mode.
    5. ./nvmflash.sh

But, I have successfully flashed an image with the ordinary flash.sh command.

$ sudo ./flash.sh -r -u /l4tpool/l4timages/emi_pkc_nano.pem jetson-nano-emmc mmcblk0p1
