Cannot build working r24.1 kernel

Autonomous Machines Jetson & Embedded Systems Jetson TX1

Knowing what the .config file content was for the kernel during compile would be useful. What was the source of your .config? Was it tegra21_defconfig? Or “/boot/config.gz”? Were there any modifications to this?

I discovered that I had to build new compilers for the kernel. They’re available in the r24.1 documentation. There’s a bjzip file jetson-tx1-toolchain-build.tbz2 which has the build.

Once I used that compiler it worked fine.
