The allowed locations for the debug handler are either (0x800 - 0x1fef800) or (0xfe000800 - 0xfffff800). The default value is 0xfe000800. +XScale has resources to support two hardware breakpoints and two +watchpoints. However, the following restrictions on watchpoint +functionality apply: (1) the value and mask arguments to the @code{wp} +command are not supported, (2) the watchpoint length must be a +power of two and not less than four, and can not be greater than the +watchpoint address, and (3) a watchpoint with a length greater than +four consumes all the watchpoint hardware resources. This means that +at any one time, you can have enabled either two watchpoints with a +length of four, or one watchpoint with a length greater than four. These commands are available to XScale based CPUs, which are implementations of the ARMv5TE architecture. |
