Reading a file from external memory via System Console

Hello, My design captures images from an external video source and records them to DDR3. In addition to my custom logic, I also have a Jtag to Avalog master connected the DDR3 controller (via Qsys)...

I've done something similar so this might help:

proc DDR3_read_to_file {} {

set imagefile [open "C:/Users/RParks/system_console/scripts/image_read.mem" w]

# set imagefile [open "/root/system_console/scripts/image_read.mem" w]

set read_data [<ddr_read_command> <addr> <length>]

# puts $read_data

puts $imagefile [format "%s" $read_data]

close $imagefile

}
