Table 4. Troubleshooting FAQs

Q1

Help! The debugger does not detect the SoC. What should I do?

A1

There are several things to check.

Upgrade the firmware. Many CC Debuggers have old firmware that will not automatically detect newer devices, like

CC2543/44/45. For further instructions, see Section 8.

Check that the cable is oriented correctly and that the pins are connected to the right signals on the debugger.

Check that the debugger gets power from the target (proper connection of the Target Voltage Sense signal). This is required in

order for the level converters on the debugger to work.

Check that ground on the target is connected to ground on the debugger. This is normally achieved through the target connector.

Note that since the ground planes are the same, be aware of any adverse effects caused by different ground planes on the target

and on the PC (grounded via USB cable).

Check that the cable and the cable adapter board are not broken. Especially the small flat cable is prone to stop working if

handled a lot or being bent and stretched beyond normal operating conditions.

Q2

Does IAR EW8051 support the CC Debugger as debugging device?

Yes, but make sure you have an up-to-date version of IAR with the new debug driver plug-in from Texas Instruments. You will

A2

need version 7.51A or higher.

Q3

Can the debugger be used as an interface to the RF device for packet sniffing?

A3

Yes, this is supported for selected devices. Use the same interconnection as in the diagrams in Section 6.

Q4

Is there a way to remove the plastic casing without damaging it?

Yes, there is. Hold the bottom piece of the plastic in one hand. With your other hand, take a firm grip on the long lateral sides of

A4

the upper part of the plastic and squeeze while moving the upper part away from the bottom. The two parts should separate from

each other.

To reassemble the plastic, just click the two pieces together.

Q5

Is this a Mini or a Micro USB plug?

A5

Mini USB type A.

Q6

I have two CC Debuggers with the same EB ID, and I’m unable to use them together. What do I do?

Two EBs with the same EB ID cause a driver conflict. The solution is to resurrect one of the CC Debuggers and give it a new EB

A6

ID.

1. Connect one CC Debugger to your computer.

2.Connect the CC Debugger you want to resurrect to a separate power source (for example, another computer or a USB

charger).

3. Follow the steps for resurrecting the CC Debugger described in Section 8.4.
