Before any directories are created # 2. After direcotries 111 and 112 are created # 3. After Directory 111 contains the uploaded files 1,2,3 and 4 # 4. After Files are deleted from Directory 111. # 5. After Directory 111 and 112 are deleted. # # # Tests on SIU, EPU0 and EPU1. # Tests on both EEPROM0 and EEPROM1 # ############################################################################################################### # system 0 - testbed host # system 1 - Spacecraft/1553 bus controller from ltx_scriptinterface import * import time def main(): #define interface - REQUIRED interface = None #always a good idea to enclose body in try/except block as LTX will throw exceptions try: #initialize the script interface -- REQUIRED interface = LTX_ScriptInterface() #start the host shell interface.start_sys(0) #start the spacecraft (SC) shell interface.start_sys(1) #initialize the systems interface.exec_ltx_cmds(0,'init') interface.exec_ltx_cmds(1,'init') #start the SC initialization interface.write_sys(1,'SCP_init 3',0) time.sleep(1) #enable Diagnostic dumps interface.write_sys(1,'SCP_setDiagnostic 10',0) time.sleep(1) # enable ITC Cmd Responses from nid=SIU, for the LAT FILE Master task (2) # for normal (not broadcast) commands from SC, when the task is functioning # purely as an executing task (0) # Parameters: node id = SIU, Task ID = FILE, class = normal, action = not forwarding task, new interface.write_sys(1,'ITC_sendCmdResponse 0,2,0,0,0',0) time.sleep(1) # send the File System Status Dump command for EEPROM0 # Parameters: latUnit: SIU, dev #: EEPROM0, Transaction ID; 378 interface.write_sys(1,'LFS_sendSysStatus 0,2,378',0) time.sleep(1) # send the File System Status Dump command for EEPROM1 # Parameters: latUnit: SIU, dev #: EEPROM1, Transaction ID; 478 interface.write_sys(1,'LFS_sendSysStatus 0,3,478',0) time.sleep(1) # enable ITC Cmd Responses from nid=EPU0, for the LAT FILE Master task (2) # for normal (not broadcast) commands from SC, when the task is functioning # as a forwarding task (1) # Parameters: node id = EPU0, Task ID = FILE, class = normal, action = forward, new #interface.write_sys(1,'ITC_sendCmdResponse 1,2,0,1,0',0) #time.sleep(1) # send the File System Status Dump command for EEPROM0 # Parameters: latUnit: EPU0, dev #: EEPROM0, Transaction ID; 578 #interface.write_sys(1,'LFS_sendSysStatus 1,2,578',0) #time.sleep(1) # send the File System Status Dump command for EEPROM1 # Parameters: latUnit: EPU0, dev #: EEPROM1, Transaction ID; 678 #interface.write_sys(1,'LFS_sendSysStatus 1,3,678',0) #time.sleep(1) # enable ITC Cmd Responses from nid=EPU1, for the LAT FILE Master task (2) # for normal (not broadcast) commands from SC, when the task is functioning # as a forwarding task (1) # Parameters: node id = EPU1, Task ID = FILE, class = normal, action = forward, new #interface.write_sys(1,'ITC_sendCmdResponse 2,2,0,1,0',0) #time.sleep(1) # send the File System Status Dump command for EEPROM0 # Parameters: latUnit: EPU0, dev #: EEPROM0, Transaction ID; 778 #interface.write_sys(1,'LFS_sendSysStatus 1,2,778',0) #time.sleep(1) # send the File System Status Dump command for EEPROM1 # Parameters: latUnit: EPU0, dev #: EEPROM1, Transaction ID; 878 #interface.write_sys(1,'LFS_sendSysStatus 1,3,878',0) #time.sleep(1) #disable diagnostic packet dumps interface.write_sys(1,'SCP_setDiagnostic 0',0) time.sleep(1) # # Analyze the results for Pass / Fail criteria # # The analysis script verifies the following for each of the LFS_sendSysStatus command that was sent: # 1.
