Problem with setting register value using MI interface

["Grzegorz Cieslewski" <cieslewski@hcs.ufl.edu>]

Hi,

I am trying to write a value to a register using MI2 interface.
Unfortunately sometimes th -var-assign command fails and gives me
error.  Does any one know why is that?

GDB<< -var-create r1 * $r1
GDB>> ^done,name="r1",numchild="0",value="2140372880",type="uint32_t"
GDB>> (gdb)
GDB<< -var-info-type r1
GDB>> ^done,type="uint32_t"
GDB>> (gdb)
GDB<< -var-set-format r1 hexadecimal
GDB>> ^done,format="hexadecimal"
GDB>> (gdb)
GDB<< -var-evaluate-expression r1
GDB>> ^done,value="0x7f937f90"
GDB>> (gdb)
GDB<< -var-info-type r1
GDB>> ^done,type="uint32_t"
GDB>> (gdb)
GDB<< -var-set-format r1 hexadecimal
GDB>> ^done,format="hexadecimal"
GDB>> (gdb)
GDB<< -var-assign r1 1
GDB>> &"mi_cmd_var_assign: Could not assign expression to variable object\n"
GDB>> ^error,msg="mi_cmd_var_assign: Could not assign expression to
variable object"
GDB>> (gdb)
GDB<< set $r1=1
GDB>> &"set $r1=1\n"
GDB>> &"Cannot access memory at address 0x1\n"
GDB>> ^error,msg="Cannot access memory at address 0x1"
GDB>> (gdb)
