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!
