I'm working with AD9963 and I wrote a no-os driver for it.
I used the AD9963 data sheet "EXAMPLE START-UP SEQUENCES" and after that wrote de-assert to axi_ad9963 dac and adc cores (Clock enable / MMCM de-assert / de-assert core).
Reg 0x40 DAC-COMMON and ADC-COMMON: https://wiki.analog.com/resources/fpga/docs/axi_ad9963#adc_channel_axi_ad.
There is no dac_valid or dac_enable.
What can I do do determine what's going wrong?
Thanks for the help,
My suggestion is to have a look over our M2K project: https://wiki.analog.com/university/tools/m2k - an AD9963 is present on this board. On the software side, a Linux driver is available: https://github.com/analogdevicesinc/linux/blob/master/drivers/iio/adc/ad9963.c
Unfortunately I mistaken and disabled the clock of the AXI_AD9963 (CE_N).
