6.1minidebug

minidebug is a small (under 16k) debugger designed to fit completely within the instruction cache on the PXA-255 processor to allow testing of boards even in the absence of ROM or RAM.

It also includes features to download over either serial or Ethernet, al- lows the display and manupulation of registers and memory, and supports controlled execution through breakpoints and data watchpoints.

Upon entry, minidebug generally displays a dot (.) prompt, sometimes pre-pended by a string that looks like $S00#b3. Fear not. The $S00#b3 string is used to allow minidebug to work in conjunction with the gdb de- bugger on the attached system.

The following is a list of commands that can be issued at the dot prompt. Note that this list can also be retrieved through minidebug by entering a question mark (?).
