21.13.1.47 read_snvm_memory

Description

This Tcl command reads client or page(s) in the sNVM (Secure Non volatile memory) memory from the device and returns a plain text (status and data of page).

Note:

If you have more than one client configured in Libero and use a client name with inappropriate -startpage, -endpage or -uskKey option values, then the command will fail.

read_snvm_memory [-deviceName "device name"] \
                 [-client "client name"] \
                 -startpage "integer value" \
                 -endpage "integer value" \
                 [-fileName "snvm data file name"] \
                 -uskKey "usk key"
