Cboot in 32.7.2 fails to read extlinux.conf

Here is the full log:
uart.log (83.7 KB)
Most of them are just booting properly from the kernel/kernel-dtb partitions. Since the default flash.sh creates those partitions properly, no one would notice any issues unless you try to overwrite using extlinux.conf.

Apparently there is a size problem:
[0005.447] I> ext4_read_data_from_extent:298: Total file read should not be larger than file stat size

If you go to your flash content’s original “boot/extlinux/extlinux.conf” source used to create the image, located somewhere like:

~/nvidia/nvidia_sdk/JetPack_...version.../Linux_for_Tegra/rootfs/boot/extlinux/extlinux.conf

…then look at the “extlinux.conf” file, what size is this file? What is the content of that file (you could attach it to the forum)? This should be the source of creating that file.

Do you also still have “Linux_for_Tegra/bootloader/system.img.raw”? If you do, then this can be loopback mounted and the actual image’s extlinux.conf examined. For example:

sudo -s
mount -o loop ./system.img.raw /mnt
cd /mnt/boot/extlinux
ls -l extlinux.conf
cat extlinux.conf
cd
umount /mnt
exit

Can anyone else who boots 32.7.2 please create a dummy extlinux.conf file and see if the uart boot log shows the same error about accessing extlinux.conf?

I have only 2 boot entries in the extlinux.conf and the file can’t be too large. The same extlinux.conf worked fine with 32.7.1.

We can reproduce this issue with pure jetpack. Will check this.

We have found exactly this issue after doing an “apt upgrade” on a machine with JetPack 4.6.1 and L4T 32.7.1.

It would be good to get a fix quickly as this is stopping us from upgrading to JetPack 4.6.2 as we need a custom dtb to be able to use SPI on the 40 pin connector.

Please try this within your cboot, reflash the cboot and it shall work with extlinux.conf.

I tried to download Cboot Sources T194 from Jetson Linux R32.7.2 Release Page | NVIDIA Developer

It can’t even build unmodified. Has anybody tried to build it as is? The tarball has some nvidia internal build tool, as pointed out in this other post.

Please follow the readme file and build it manually.

Here is what I did on my Debian x86_64 box:

  1. Downloaded cboot_src_t19x.tbz2 and l4t-gcc-7-3-1-toolchain-64-bit into /tmp from Jetson Linux R32.7.2 Release Page | NVIDIA Developer
cd /tmp
rm -rf cboot
mkdir cboot
tar -C cboot -xf cboot_src_t19x.tbz2
tar xf l4t-gcc-7-3-1-toolchain-64-bit
export CROSS_COMPILE=/tmp/gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-

No such file or directory: '/tmp/cboot/.repo/manifest.xml' is what is mentioned in this other post.

ok, found the issue in the file bootloader/partner/t18x/cboot/make/macros.mk

As suggested in this post, I modified the line 14,15 from

SPACE :=
SPACE +=

to

E =
SPACE = $E $E

The build completes, though still giving the error No such file or directory: '/tmp/cboot/.repo/manifest.xml'. I guess that could be ignored.

Is this cboot patch also fixing this? If not, can you provide one as well?

Honestly, we don’t think that is really a bug… That was why we didn’t have any fix.

The record of the conclusion from my side is, your issue should just be avoided by changing the boot order in the cbo.

If that does not resolve your issue, you need to share the log but not just tell us it is a bug.

I mean we need the log for this status.

But turns out you come back and tell us the rel-32.7.2 extlinux.conf issue. That was different case.

The original problem that we had 209345 was that we could not turn the SPI on using JetsonIO. That was a bug. After some considerable time looking at this we discovered that it was because the boot procedure was not properly checking all the available boot options in the boot-order and was giving up at nvme when one was present. Having remedied (ie not fixed) that by changing the boot order, the next machine we tried to set up we could no longer boot with our custom dtb that was turning SPI on and after some more considerable time we discovered that it was because extlinux.conf was not not being read and thus found this thread.

So I am inclined to agree with user100090 that these are all related and part of the same issue. Recompiling cboot is clearly raising more bugs and I am not inclined to try it and will rather stick with 32.7.1 and change to boot-order.

So when will the combined boot-order + extlinux.conf bugs be fixed?

Can someone at least show us what is the exact error you got when you change the boot order and with the extlinux.conf patch?

My purpose here is only “if your nvme is not a boot disk, then please move it out from the boot order”

My point is that if the boot-order was worked through without giving up at the first device found, there wouldn’t be a problem. Even if there was an option to edit the boot order as part of the Jetpack installer then that wouldn’t be a problem. Ok it is quite easy to edit the boot order once you know what to do, but starting from a position of not even knowing what a dtb was then that involved quite a bit of reading. My interpretation of this thread is that user100090 has successfully recompiled cboot after editing one of the makefiles and I presume that their system is now booting correctly. If you are interested in another log from when it does not read extlinux.conf correctly without recompiling cboot but after changing the boot order then see below:

Hi,

The error you posted is just the patch we shared out. If you don’t want to compile the cboot, then you can only wait for the next release.

My point here was user100090 seems telling us he still has a bug on his side with the boot-order issue. So I would like to know what is that.

I have replied in the original thread in this post. Maybe it is not clear. Let me re-state here. The boot-order issue is not really a boot-order issue, but when boot-order was changed and the extlinux.conf on the emmc is finally being read, a different problem in extlinux.conf caused the boot failed. At the time I didn’t have the uart console access so thought the boot-order change caused the boot failed. But in reality, the boot-order change revealed a different compatibility issue in extlinux.conf

The extlinux.conf had the default entry:

TIMEOUT 30
DEFAULT primary

MENU TITLE L4T boot options

LABEL primary
      MENU LABEL primary kernel
      LINUX /boot/Image
      INITRD /boot/initrd
      APPEND ${cbootargs} quiet

# When testing a custom kernel, it is recommended that you create a backup of
# the original kernel and add a new entry to this file so that the device can
# fallback to the original kernel. To do this:
#
# 1, Make a backup of the original kernel
#      sudo cp /boot/Image /boot/Image.backup
#
# 2, Copy your custom kernel into /boot/Image
#
# 3, Uncomment below menu setting lines for the original kernel
#
# 4, Reboot

# LABEL backup
#    MENU LABEL backup kernel
#    LINUX /boot/Image.backup
#    INITRD /boot/initrd
#    APPEND ${cbootargs}

It worked fine in JP 4.3, but now it failed the boot, because ${cbootargs} in the APPEND line no longer includes root=/dev/... so I have to explicitly specify the root device. After I change APPEND ${cbootargs} quiet to APPEND ${cbootargs} quiet root=/dev/mmcblk0p1. It started to boot.

Hi,

Do you still need to do that after you enable our extlinux patch in cboot?

Could you tell me if there is any error on your side if you don’t do any other change except the extlinux cboot patch we provided?
I don’t think it is normal that you need to append the root=xxxx to your extlinux.conf manually.

If there is any problem, could you share me the log?
