Jetson TX1 24.1 Release need help with complier directions , can not complie

Autonomous Machines Jetson & Embedded Systems Jetson TX1

Well this is what I did:

./source_sync.sh -k tegra-l4t-r24.1 -u tegra-l4t-r24.1
git apply compiled.patch
//... Normal build steps as you detailed earlier.
//... Flashed to eMMC using Jetpack (mainly so that I can install cuda, opencv...
//... Booted (installed jetpack stuff) rebooted,
//... So far so good

The changes applied (ignore USB ones, they are for the DUO camera)

Note the change to Makefile. It boots and seems normal so far. How can I check if this has had any effect?

I don’t know about completely validating this, but the fact that it compiled and runs at least partially tells you the armv8-a and -fomit-frame-pointer changes succeeded. The changes which clarify the cstate line must also work, as the compiler did not reject it. I suspect that for testing the USB patch you won’t know until something which previously failed no longer fails.

I am getting same error from R24.2 how you solved those errors?

Hi RiteshPanchal,

Please try release 24.2.1 toolchain. Thanks!

I have to revive this thread because I’m getting exactly the same error. I’m using the 24.2.1 toolchain. Following the doc from: http://developer.nvidia.com/embedded/dlc/l4t-documentation-24-2-1

When executing “make O=$TEGRA_KERNEL_OUT zImage” I get the error:

/home/sd2/jetson_tx1/toolchain-build-aarch64/install/bin/aarch64-unknown-linux-gnu-ld: cannot find libgcc.a: No such file or directory
/home/sd2/jetson_tx1/toolchain-build-aarch64/install/bin/aarch64-unknown-linux-gnu-ld: cannot find libgcc.a: No such file or directory

It wasn’t easy to get to this point, and now I’m stuck.
I’m trying to build the kernel on a Ubuntu 14.04 system.

I want to install the following patch:
https://devtalk.nvidia.com/default/topic/967515/jetson-tx1/l4t-r24-2-pcie-iommu-not-working-when-switches-bridges-are-present/post/4982441/#4982441

Eventually I want to install the patch on our TX2 system, but that’s a different code basis. On the TX1 I want to verify if the patch solves my issue. For the TX2 I’ve found a tutorial which is easy to follow: http://www.jetsonhacks.com/2017/03/25/build-kernel-and-modules-nvidia-jetson-tx2/

Is there a similar tutorial for the TX1?

26

There is a similar JetsonHacks article for building the kernel on the Jetson TX1:

Good luck!

27

Here are some notes on TX1 kernel compile:

I have a Fedora host so I use Linaro instead of deb packages (or the compiler tools in the documentation). If interested, here are some precompiled binaries:

This is a little embarrassing that I didn’t find the page on jetsonhacks. Worked eventually, after overcoming the space limitations of the TX1 :)

Thanks guys!
