Dear Florian,
I use the following settings when using Lauterbach on the TX1 (otherwise
the watchdog reboots the machine after blocking):
echo 0 > /sys/devices/system/cpu/cpuquiet/tegra_cpuquiet/enable
echo 1 > /sys/kernel/debug/cpuidle_t210/fast_cluster_states_enable
echo 1 > /sys/kernel/debug/cpuidle_t210/slow_cluster_states_enable
echo 1 > /sys/kernel/debug/clock/csite/state
echo 0 > /proc/sys/kernel/nmi_watchdog
echo 0 > /proc/sys/kernel/watchdog_thresh
echo 0 > /proc/sys/kernel/watchdog
Hope it helps.
Best regards,
Claudio
