JTAG to Avalon master bridge usage

Hi,

Thanks a lot for the reply. I tried communicating through system console, but was getting some errors.

set jtag_master [lindex [get_service_paths master] 0]

open_service master $jtag_master

The above two commands worked properly. But when i tried the command master_write_32 $jtag_master 0x400 0x00000000, i am seeing the following error.

error: java.lang.RuntimeException: This transaction did not complete in 60 seconds. System Console is giving up.

while executing

"master_write_32 $jtag_master 0x400 0x00000000"

What could possibly be a reason for this error.

is_service_open command returns 1.

Thanks in advance
