plutosdr get chan error

hello I am tring to use matlab with ad9363+ zynq ,the firmware is plutosdr v0.38 built by myself,the iio version is v0.25

the matlab code is

warning('off','plutoradio:sysobj:FirmwareIncompatible');

%%ad9361配置

tx = sdrtx('AD936x',...

'IPAddress','192.168.5.23',...

'ChannelMapping',1)

radioSettings = info(tx)

tx.CenterFrequency = 2.415e9;

tx.BasebandSampleRate = 2e6;

tx.Gain = -5;

%% 信号波形设置

sw = dsp.SineWave;

sw.Amplitude = 0.5;

sw.Frequency = 100e3;

sw.ComplexOutput = true;

sw.SampleRate = tx.BasebandSampleRate;

sw.SamplesPerFrame = 1000;

txWaveform = sw();

%%发送信号

transmitRepeat(tx,txWaveform)

release(tx);

the error is

包含以下字段的 struct:

Status: 'Unable to setup device'

MsgDetails: 'Channel: altvoltage4 not found.'

11 tx.CenterFrequency = 2.415e9;

## Establishing connection to hardware. This process can take several seconds.

transmitRepeat(tx,txWaveform)

but I think the firmware is ok because I test it on GNU Radio and ADI IIO Osi they both work.

when I swith the sdrtx('AD936x' to sdrtx('pluto',I get the error

The radio with ID usb:0 is already owned by a block,

Hi Zheng,

It sounds like the error message 'Channel: altvoltage4 not found' suggests a problem with the channel configuration. This issue might be due to a mismatch between the channel names expected by Matlab and the actual channels available on the hardware.

To resolve this, ensure that the channel names in your Matlab code match the channels available on the AD9363+ Zynq hardware. Double-check the channel mappings and configurations in your code. Additionally, verify that the hardware is correctly initialized and that the connection settings are accurate.

If switching from 'AD936x' to 'pluto' results in the error 'The radio with ID usb:0 is already owned by a block,' it indicates that the radio device is already in use by another process or block. Make sure to release the device properly before attempting to reconfigure or reconnect it in Matlab.

By addressing these channel mapping and device ownership issues, you should be able to establish a successful connection between Matlab and the AD9363+ Zynq hardware.
