get value from master_read_32

Hello evryone,

I am trying to do a GUI interface with tcl to load the .sof that I generated into the FPGA with tcl.
I want also in this tcl script read from a memory adress, get a value and put it into a label in the GUI interface.
I am using master_read_32 command to do this:

#set m_path [lindex [get_service_paths master] 0]


#open_service master $m_path


#master_read_32 $m_path 0x00000000 1

to read the 32 bit value.

My question is how can I save this value to put it into the label in the GUI interface!?

I am waiting for some help please.
Thanks a lot.
