Now, I have a little issue: I have compiled a new rtems BSP, I checked it in gdb - it copies .data section. Then I clean examples-v2 by doing './waf clean', then do ./waf configure and build with './waf'. After that, I am getting mistake and build only low_ticker example with ./waf. But, when I try to run it on the target, though I can see the proper code via 'list' command, I can't go through the code. For example, though I have added the code for data copying and can see it in gdb with 'list' command, I can't step through it. What could be the reason? -- Regards, Denis Obrezkov
