6. START-UP METHOD (POWER-ON SEQUENCE)
To start up the S5U1C33001H system, follow the sequence described below:
(1) Connect the S5U1C33001H to the host computer using the USB cable.
The LED1, LED2, and LED3 operate as follows:
LED1 (Green, ON)
LED2 (Red, ON)
LED3 (OFF)
(2) Turn the target system on.
The LED1, LED2, and LED3 operate as follows:
LED1 (Green, ON)
LED2 (Blue, ON)
LED3 (Green, ON)
(3) Start up the debugger (gdb.exe) on the host computer in ICD mode.
To terminate the S5U1C33001H system, follow the sequence described below:
(1') Terminate the debugger (gdb.exe) on the host computer.
(2') Turn the target system off.
(3') Turn the S5U1C33001H off.
Notes:
• Normally the S5U1C33001H system can work properly when the target system is turned on first and then
the S5U1C33001H. However, the power-on sequence described above is recommended since the system
may not work properly if the target system is in indeterminate operation or in runaway status.
• If the debugger (gdb.exe) is terminated after the S5U1C33001H is turned off, the debugger may not work
properly with "Cannot open ICD33 usb driver." displayed on the screen when it is re-invoked. In this case,
turn on or reset the S5U1C33001H after terminating the debugger (gdb.exe) once, and then re-invoke the
debugger.
For details on how to invoke/terminate the debugger, refer to the "Debugger" section in the
"S5U1C33001C Manual (C Compiler Package for S1C33 Family)". Furthermore the debugger (gdb.exe)
must be invoked after turning all the power of the system on.
Check the following if the debugger reports a target down error, which means that communication
between the S5U1C33001H and the target system is not functioning.
• If the target system power is turned on after the S5U1C33001H is turned on:
After the S5U1C33001H power is turned on, a forced break will be applied continuously to the target
system. After the target system is turned on, the S1C33xxx chip is reset. The S1C33xxx chip enters
debug mode and starts communication with the S5U1C33001H.
If multiple power on/reset cycles occur caused by switch bounce when the target is turned on, the
