AWR1843: Would like to know the time until TX output after power on.

Hi Hitoshi San,

This timing depends on the no. of APIs application invokes till rlSensorStart.

At sensorStart device starts chirping and transmit Tx signal.

Could you provide the reason for measuring this timing?

This you can measure in the application.

If you need to measure the same from the bootup, then here is one of the option.

1. Add GPIO toggle at rlSensorStart API to notify externally Tx transmission.

2. Probe to nReset and above used GPIO.

So using logic analyzer you can measure the timing between nReset to GPIO high/toggle. This is your full time from device bootup to Tx streaming.

* Application boot time depends on application size and sFlash device variant.

Let me know if you have any further query.

Regards,

Jitendra
