9 Troubleshooting
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 CC2540 and CC2541. These devices need firmware version 13 or
newer. Refer to chapter 8 for further instructions.
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 (i.e 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, please
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 is 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?
A2 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 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
chapter 6.
Q4 Is there a way to remove the plastic casing without damaging it?
A4 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 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.
