No response while changing RX center frequency

[lys8934]

Hi,

I am trying to change RX center frequency. I added chillipepper interface to Xillybus and tried to change frequency. I can get responses from Chilipepper by two commands but when I write third one, there is no response from Chilipepper and the green LED on Chilipepper is off.
Do I have to disable RX or any others before changing center freqeuncy?

Set freq=2450000, 0x256250
Send data=ff, 4, 25, fe
Recv data = ff, 4, 25, fe

Send data=ff, 4, 62, fe
Recv data = ff, 4, 62, fe

Send data=ff, 4, 50, fe
----- No response

Thanks,
Yong

Does this freeze the board? I.E. if after getting no response you re-send a previous command that you know worked, does the board respond as normal? I will attempt to duplicate your error.

No, the board does not respond at all(the green LED is off). I sent the LED turn on command, but the LED is still off. After I press the button on the Chilipepper board, it responds(The green LED is on),
