Hi, How do I capture all the output of user-space programs into a kernel buffer so that I can later read it using debugger ? My board doesn't have a console (no serial, no network). Any direction would be of great help. sumesh.

Assuming you are using a shell to start your user-space programs, you could easily redirect output to /dev/kmsg then find it in the dmesg buffer afterwards. You may need to increase the buffer size. Clive
