CCS/CC1352P: Boost mode

Part Number: CC1352P
Other Parts Discussed in Thread: SYSCONFIG

Tool/software: Code Composer Studio

How do you disable/edit boost mode in SDK v3.40 for CC1352P?

Boost Mode

In order for the Power Amplifier to output the maximum 20 dBm TX power in IEEE mode, Boost Mode is enabled inside of the TX power tables in the application. Boost Mode increases the VDDR from 1.7 V to 1.95 V, which increases the maximum TX power output from 17 dBm to 20 dBm, while also increasing current consumption by 15%. The TX power tables are located inside the mac_user_config_[DEVICE]r1_rftable.h file. You can find this file for the CC1352P device in the SDK installation directory:

C:\ti\<SimpleLink SDK>\source\ti\ti154stack\common\boards\mac_user_config_cc13x2r1_rftable.h

This file does not exist, but it is still part of the documentation

Hi,

After you build the CC1352P project, syscfg will generate the file ti_radio_config.c (<project>\default\syscfg\).
The powertable should be there.

Thanks for bringing this to our attention, we'll work to keep the documentation up to date with the SDK.

Regards,
Toby

But as soon as you Build those files get re-generated. It also goes against normal convention to edit generated C files. Don't you agree?

Yes, usually you'd want to enable to PA on P devices, but I suppose it should also be an option to disable it (as it was possible before).

I'll notify the team to see what we can do.

So to be clear, Boost can't be disabled at with this SDK v3.40?

Not directly through sysconfig.

It's possible to disable sysconfig.
Please refer to http://dev.ti.com/tirex/content/simplelink_cc13x2_26x2_sdk_3_40_00_02/docs/ti154stack/html/sysconfig/sysconfig-disable.html

Thanks for the link

But ideally, we wouldn't need to disable part of the default build system to change the Boost mode.

We'll investigate options to fix this; it'll likely be in a future release.

What would be super great. How do I keep up with the SDK news of the day?

The latest SDK will be available here:

Along with release notes, etc.
