I am trying to trace a Jetson tx1 with a Lauterbach debugger using the onchip trace buffer. The system is running a Linux4Tegra build with Yocto.
Using the scripts provided in l4t-documentation-24-2 I can debug the kernel and user space programs. But the scripts do not configure the onchip trace buffer, so I can´t trace a program.
Then I tried the scripts provided by Lauterbach. With them, I am able to trace a program, but only when I load it directly into RAM and execute it from there. If I try to trace the kernel I get a error message (Unlocking of debug registers failed) and the system freezes while booting.
Has anyone experience with tracing a Jetson TX1 board?
