35 This scripts reads an OP-TEE abort or panic message from stdin and adds debug
37 address in the call stack. Any message generated by OP-TEE and containing a
49 OP-TEE abort and panic messages are sent to the secure console. They look like

68 Also, this script reads function graph generated for OP-TEE user TA from
