Kernel debug on NVIDIA Tegra 2 platforms

Applies to: DS-5

Answer

DS-5 includes support for the NVIDIA Tegra 2 platform.

If you wish to use JTAG debug and your target is running Linux or Android you must ensure that the kernel is built with the CPU_IDLE option turned off. To do this use the 'make menuconfig' interface to disable the "CPU idle PM support" entry inside the "CPU Power Management" group and rebuild the kernel.

Failure to disable this config item, will prevent any debug connection once Linux boots.
