CC2511 Dongle

5.2Known 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)
