how to modify gain table region during runing under AGC mode？

You can not change the Gain table during run time. While initialisation, you would be loading the Gain table.

And all the AGC related configuration settings are part of ADRV9025_AgcCfg_t Structure Definition.

sorry,it's my fault.

I have not expressed my idea clearly.

I clarify my idea as following:

1.I don't change the Gain table which is loaded during initialization.The agcRxMaxGainIndex is 255,the agcRxMinGainIndex is 195 defaultly.

2. I only want to change agcRxMaxGainIndex and agcRxMinGainIndex which determined the agc dynamic region. I expect that it work simultaneously when I modify the parameter of agcRxMaxGainIndex(eg.245) and agcRxMinGainIndex(eg.200) . Does it come ture when I call the API adi_adrv9025_RxMinMaxGainIndexSet() ,adi_adrv9025_AgcReset()  in proper order?

3. I only konw that 9025 should be reset and re-initaliazed when agcRxMaxGainIndex and agcRxMinGainIndex is changed. This is not my expectation. I want to it take  effective when agcRxMaxGainIndex and agcRxMinGainIndex is changed.

You can not change the agcRxMaxGainIndex and agcRxMinGainIndex during run time and on the fly.

You need to re-initialise the chip.
