CC1120: Unable to start Packet TX with dev kit

cc1120user

Part Number: CC1120

So when I press the start button on the Packet TX tab, it manages to send 3 packets but then the program freezes. Eventually I get a window asking me to restart the Device Control Panel. This is repeatable and happens every time with these settings:

What am I doing wrong?

Hi,

I have notified an expert to look into this.

In the meantime, are these the default values?
If not, does it work with default settings in SmartRF Studio?

Thanks,
Toby

I assume you are using SmartRF Studio

Which exact hardware are you using?

The same can be seen if you haven't connected GPIO2 from CC1120 to the EM connector.

I am using the cc1120 development kit, the Smart RF TX board specifically.

The board works with the default values.

@TER, are you suggesting to change the GPIO2_CFG register? What should I change it to?

Do you use the TRXEB (https://www.ti.com/tool/SMARTRFTRXEBK) with a CC1120 EM (https://www.ti.com/tool/CC1120EMK-868-915)?

Yes

After you have imported the .cfg file.

press on the number and write 06 here. As you see this is used for the other settings.

Thanks for the suggestion TER,

But this did not seem to fix the issue. I get the same error message.

I don't have a CC1120 EM here. You can try to start with a setting in SmartRF Studio where you are able to send more than 3 packets and change the register values one by one to reflect your settings. Start on the top and see which one that causes things to crash.
