get value from master_read_32

Hello Dave,

Thank you so much for your help. It helped me a lot but now I am stuck in something that without this I can't finish.

In this procedure:

proc read_button {} {

global jtag

# The address and data entry boxes contain only digits,

# so add the leading 0x to the address

set data [jtag_read 0x$jtag(address)]

# and then strip the response 0x

set jtag(data) [format %X $data]

}

I can't get the adress of the JTAG. I am using JTGA_to_Avalon_MM. Is because of this?

The adress in Qsys is 0x00000000.

Can you help me please? Because I am receiving this error: can't read "jtag(address)": no such element in array

Kind regards
