I'm using Development Studio and trying to load linux kernel of Linaro on FVP.
After building kernel, the vmlinux was loaded successfully (Base_A53x1) but when I clicked the button of 'Step Source Line", I got the error message below.
ERROR(CMD440-TAD10-NAL23): ! Stepping failed! Failed to read 4 bytes from address EL3:0xFFFF000010080000! Memory read from model failed.
Is there any build option or model parameter in Debug Configuration for this situation?
Thanks
