FMCOMMS1 ACCESS TO AD9523 REGISTER

Hi,

 

 

 

I work with FMCOMMS1 and Zedboard. I use a reference design load with SD card. I can start linux and logon via UART or SSH.

 

I found the sysfs corresponding to the AD9523 IIO and can get the status of the PLL.

 

The next step we want to do is to configure the external clock reference (REFB) but I didn't found files associated to the control register of PLL (Reg 0X01C).

 

I see there is some control register like set the DAC CLK frequency:

root:/> cat out_altvoltage1_DAC_CLK_frequency

491520000

 

 

Is there a similar way to configure the control register 0X01C ?

 

We are interested of any suggestions to quickly configure the FMCOMMS1 (Gui, script bash...)

 

 

 

Regards,

 

Lionel
