RTOS/CC2652R: OTA

Tool/software: TI-RTOS

Hello members

Let me ask one question.

I am using OTA firmware upgrade functionality on CC2652R.

I implemented OTA Client on my End-Device side and it works very well.

But problem is that after included OTA functionality, the standby current goes high.

It is now 34mA

So I tried that with sample(zed_sw_ota_client_CC26X2R1_LAUNCHXL_tirtos_ccs) to check that it is my fault, but on sample it is also consuming sample current on standby mode

Can anyone tell me why this happens and how to solve it?

Hi,

Is this on a launchpad or a custom board? I would not expect such a large current number on a launchpad...

What you're seeing may be due (in part) to the known issue that the TI-RTOS debug configuration is used by default in the project.

Please try the following steps to use the TI-RTOS release configuration:

Delete ‘oad_app.cfg’ from the SDK
Make a copy of ‘app_release.cfg’ and rename it to ‘oad_app.cfg’
Change the following line in the new ‘oad_app.cfg’
1. m3Hwi.resetVectorAddress = 0x50;
Reimport any OTA Client projects, or copy the new ‘oad_app.cfg’ into your CCS workspace to replace the original version.

Toby

This sounds like there’s current leakage on your IO pins so I suggest you to check if your IO pins are all configured correctly.

Hi Toby,

This is the procedure I followed. But, consumption still 4mA standby using SDK3.10.
