Hello, Thanks for your replies. Let me tell a few words about debugging emvironment I've used Devkit8000: http://www.armkits.com/Product/devkit8000.asp It came with Linux preinstalled. From user guide I've taken an example program that makes leds blink and cross-compiled it with debug symbols included. I didn't recompile Linux kernel, but I think everything will be the same.
I've launched the system this way: 1) Powered on Devkit8000 2) On my linux host launched OpenOCD: sudo openocd -s /usr/local/share/openocd/ -f interface/olimex-jtag-tiny.cfg -f target/omap3530.cfg -d 3 3) On cross-GDB (arm-linux-gnueabi-gdb) entered commands: target remote localhost:3333 monitor gdb_breakpoint_override hard monitor omap3_dbginit omap3530.cpu monitor halt Two last commands can be substituted with "monitor reset halt". Command "monitor gdb_breakpoint_override hard" is critical. It tells gdb to use hardware breakpoints. Now GDB is connected to the device and device is stoped and ready to be debugged. You can use usual GDB commands like: backtrace, break, step, stepi, print, x, ... And also Openocd commands in GDB like: monitor virt2phys, monitor mww, ... I'll attach some logs of debugging session on Monday.
