Usage of the "var" command?

Development Boards MicroMod

Hello!

I’m trying to use the “var” command in the following way:

var myfunction 0x810000ec
reg pc myfunction  # this don't work
reg pc 0x810000ec  # this works

Does anybody have an example how to properly use the “var” command?

The ‘var’ command currently only works with the low-level JTAG subsystem:

(use a config file without a “target …” line or any other target specific config statement)

endstate rti

irscan 0 0xe

var id 32

drscan 0 id

var id

This enters the IDCODE JTAG command, declares a variable “id” with one 32-bit field, executes a data-register scan that loads “id”, and displays the content of “id”.

Regards,

Dominic
