TROUBLESHOOTING

The following shows the problems attributable to the hardware:

Table 13 Troubleshooting

Symptom

The EMU/ERASE LED that has lit when the
S5U1C33001H is turned on does not go out.

The following message appears when the debugger
(gdb.exe) in the host computer is invoked:

Cannot open ICD33 usb driver

The bus trace function is enabled, but trace
information cannot be obtained at all.
The operation is unstable.

Cause/remedy

(1) Is the target system turned on?

→

Turn the target system on.

(2) Is the target system connected with the S5U1C33001H?

→

See the "Connecting the Target System" section in this manual and check to

see if the target system is connected correctly.

(3) Was the power-on sequence correct?

→

See the "Start-up Method (Power-on Sequence)" section in this manual and

turn the power on in the correct order.

(1) Is the S5U1C33001H turned on?

→

Place the power switch on the rear panel of the S5U1C33001H in the "I"

position.

(2) Is the S5U1C33001H connected to the host computer correctly?

→

See the "Connecting the S5U1C33001H and the Host Computer" section in

this manual and check to see if the target system is connected correctly.

(3) Was the debugger (gdb.exe) restarted after resetting the S5U1C33001H while

the debugger is running?

→

See "Notes" in the " Start-up Method (Power-on Sequence)" section in this

manual.

(1) Is the 30-pin coaxial cable connected to the target system?

→

Use the 30-pin coaxial cable.

(1) Is the DCLK-core clock ratio (SW2 and 3) set correctly?

→

See the "DIP Switches" section in this manual and make sure that the setting

is correct.

(2) Is the DSIO output level (SW8) set correctly?

→

See the "DIP Switches" section in this manual and make sure that the setting

is correct.

(3) Is the target system connected with a cable other than that supplied, or the

supplied cable extended with wires?

→

Use a supplied cable.

(4) Are the 30-pin coaxial cable and 10-pin or 4-pin cable used simultaneously?

→

Use either only the 30-pin coaxial cable, 10-pin or 4-pin cable.
