On my LS1046A-FWY board, I am running the Yocto Linux 3.1 SDK. It boots and runs fine from TFTP. However, I'm having difficulty getting a proper connection with CW (Evaluation Version: 11.5.5) on Windows 10.
I am able to connect to the board, but I get a warning that "Linux Kernel Awareness Support is Disabled", and then CW breaks into the ARM core 0 at 0xfbe05d38. Only core 0 is shown in the debugger. I think this location is cpu idle since the instruction is ret, and the previous instruction is wfi in the disassembly window.
I created a source mapping to the linux-qoriq git directory, but no source debugging is shown when the code breaks.
Once it breaks, I can resume, and the kernel continues to run fine.
I have reviewed all my settings, but I am not able to understand why I'm only seeing one core, why I'm seeing the warning about kernel awareness disabled, and why CW doesn't seem to be mapping my source properly.
I also tried the following:
hbreak cpuinfo_open
Hardware assisted breakpoint 1 at 0xffff8000102e9460: file /usr/src/kernel/fs/proc/cpuinfo.c, line 15.
And then on Linux:
# taskset 1 cat /proc/cpuinfo
but the breakpoint doesn't trigger.
Thanks.
