display

Use the display debugging command to:

• Display the contents of a register or memory location

• List all the register sets on a target

• Add one or more register sets, registers, or memory locations to the default

display items

• Remove one or more register sets, registers, or memory locations from the default

display items

The memory output radix is specified by the radix command.

When you display registers or memory locations, the display command returns the

values to Tcl. Consequently, you can embed the display command to Tcl as follows:

set r0 [display r0] ; puts $r0 ;

set r0M [display p:$r0 32bit] ; puts $r0M

set r0r1 [display r0..r1] ; puts $r0r1 ;

This command’s default memory display is 16-bits per unit; you can change that by

specifying unit size as 8bit, 16bit, 32bit, 64bit.
