Dear Sir/Madam,

 

I need your help!

 

I just got the question from our customer.

He is designing with your AD-FMCOMMS1-EBZ and Zed Board by your user guide (http://wiki.analog.com/resources/eval/user-guides/ad-fmcomms1-ebz).

So he can make work your "IIO-Oscilloscope" and Reference-HDL-design on it.

 

But when he embed his original QPSK-Tx-HDL-design on it, then he cannot access to AD9122 register.

 

I enclose the  error message of Linux boot log.

Please refer to (line 216-217) as following.

 

---the start of quote ---

ad9122 spi32766.0: Failed DCI calibration

cf_axi_dds: probe of 74204000.cf-ad9122-core-lpc failed with error -5

--- the end of quote ---

 

What does this message mean?

Otherwise what should we check for this trouble?

Please give me your good advice!

 

Thanks Kaos
