Hi List, I am trying to use ftrace on a P2020 board, using the following : - Linux 2.6.35-11 - Xenomai 2.5.5.1 (or 2.5.6, same problem) - ipipe 2.12-01
I launch it using : $> mkdir /tmp/debug $> mount -t debugfs nodev /tmp/debug $> cd /tmp/debug/tracing $> echo function_graph > current_tracer The last one fails (it hangs the CPU, I cannot do anything than hard reset). Do you know what could cause that ? As I can't have any trace, I don't really know how to go further, and before using a BDI I would like to know if it is a known issue, as I could not find anything related to this in the recent changes... Thanks in advance for your help, Regards, JM
