4 Connecting CC2511 Dongle to SmartRF04EB.

Please see the “CC2430DK_CC2510_CC1110_User_Manual” for more information on the SmartRF04EB and how to use the CC2510EM. Make sure to install SmartRF SmartRF

The CC2511 have a 2 wire debug interface that is used for chip programming and debugging. When connecting this interface to the SmartRF04EB USB MCU, the CC2511 can be programmed from the Chipcon Flash Programmer software and debugged from IAR embedded workbench..To connect the CC2511 Dongle to the SmartRF04EB follow these 6 steps:

1. Turn off the SmartRF04EB power by moving the power switch to the left position. See Figure 3.

2. Remove any CCxxxxEM modules attached to the SmarRF04EB.

3. Connect the SmartRF04EB to a PC with the supplied USB cable.

4. Connect the CC2511 Dongle to the SmartRF04EB with the supplied 10 pin cable.

5. Power the CC2511 Dongle.

Studio can be downloaded from the www.chipcon.com or www.ti.com/lpw

The cable should be mounted between the “SoC debug” connector on the CC2511 Dongle and the “P14 SoC debug / flash” connector on the SmartRF04EB. Make sure pin 1 is connected to pin 1. This cable connects the debug interface and GND between the two devices, however the CC2511 Dongle cable.

To power the CC2511 Dongle there are two options:

• Powered with a USB cable. Using the supplied USB extension cable to connect the CC2511 Dongle to the PC. See Figure 1.

• Powered from the SmartRF04EB. Connect pin 9 on the “Test pin” connector on CC2511 Dongle to pin 5 on the “I/O A” connector on SmartRF04EB to power the Dongle from the SmartRF04EB. See Figure 2.

The CC2511 Dongle should only be powered by one of the two sources at a time. Do not connect the USB cable to the CC2511 Dongle while it is powered from the SmartRF04EB. The SmartRF04EB have a level converter on the debug connector, so the SmartRF04EB and the CC2511 Dongle may have a different power supply voltage.

The CC2511 can now be programmed with the Chipcon Flash Programmer software. The firmware on the CC2511 can also be debugged using the IAR embedded workbench debugger. Please see the IAR user manual and the Chipcon Flash Programmer user manual for more details.

5 Using SmartRF04EB as an In-Circuit Emulator (ICE)

The SmartRF04EB can be used as ICE for the CC2511 To use the SmartRF04EB as ICE, the IAR Embedded Workbench software must be installed.

The Embedded Workbench is a C-Compiler, Simulator, and ICE debugger. See the IAR Embedded Workbench documentation supplied with the kit for instructions how to set up the ICE debugger for use as an ICE.

When the SmartRF04EB is connected to a PC with the USB port, the debugger will connect to the SmartRF04EB. Several SmartRF04EB can be connected to USB ports simultaneously. A selection window will display the connected SmartRF04EB, and the user can select which device to load.

For custom PCB’s with the CC2511, it is recommended to include a pin header or test points to allow in-circuit emulation or programming using SmartRF04EB or other 3rd party programming tools. Use the CC2511 Dongle as a reference. Please see the CC2510/CC2511section of the Chipcon web site for an updated list of 3rd party programming tools.

When using smartRF04EB as emulator for external target debugging any CCxxxxEM module must be removed

The pin-out used on the SmartRF04EB is explained in Table 1 and Figure 4. The connector includes 4 SPI control signals. These are currently not used, but they are included to give users flexibility.

Table 1: P14 SOC debug connector pin-out

VDD note: The SmartRF04EB includes a voltage converter to support programming and

debugging of external systems with different voltage than the SmartRF04EB. The debug connector includes two VDD connections on pin 2 and pin 9. The function is different for these connections.

Pin 2 VDD supplies voltage to the voltage converter. If the target application is self powered pin 2 should be connected to VDD to assure that the correct supply voltage is used for the voltage converter. This pin must always be connected to VDD.

Pin 9 VDD supplies 3.3V from the SmartRF04EB. If the target application is powered from the SmartRF04EB supply during programming and debugging this pin can be connected to VDD. If the target voltage differs from 3.3V, this pin should not be connected. On the CC2511 Dongle this pin is not connected. Hence the CC2511 Dongle must be powered from a separate USB cable or a separate cable connecting pin 9 on “test pins” / P4 to VDD on the SmartRF04EB. See chapter 4 for details.

5.1 Debugging USB firmware

When writing and debugging USB firmware one should remember that when Windows (or another OS) detects a USB device it will assume that it works in accordance with the USB specification. During debugging this might not be the case. Breakpoints may stop the execution of code on the CC2511 Dongle and firmware under development may not be completed or error free. This may lead to the PC disconnecting the CC2511 Dongle and turning off or toggling its power supply. In some cases Windows (or the OS in use) may crash or misbehave. Hence breakpoints should be used with caution.

Obviously inserting and using breakpoints in the firmware during debugging will be extremely useful to pinpoint bugs and follow code execution. And they can and should be used. But they will also stop the code execution on the CC2511 and may cause the device to act in conflict with the USB specification. This can lead to the PC disconnecting the CC2511 Dongle, sending a USB reset or worst case the operating system may crash.

If the firmware contain bugs that make the PC disconnect the CC2511 Dongle it may be necessary to disconnect the USB cable, and power the CC2511 Dongle from the SmartRF04EB in order to reprogram it.

5.2 Known problems

When using the debug interface through the level-converter on the SmartRf04EB. (Shown in Figure 1 and Figure 2) it might become unstable. This problem is more likely to occur a low voltages or with crosstalk in the cable at high interface speed.

First make sure that the 10 pin flat cable used to connect the CC2511 USB Dongle to the SmartRF04EB is as short as possible. Next it might be necessary to reduce the debug interface speed in order to achieve stable operation. In the IAR workbench do the following:

• Highlight the project name by clicking on it in the “Files” window. (See Figure 6)

• Go to Project -> Options…

• Select the Category “Chipcon”

• Click on the “Target” tab.

• Check the “Reduce interface speed” option. (See Figure 7)
