Product Number: zcu102 + FMCDAQ2
Software Version: custom tcl supplied by Travis Collins
Hi,
We need to boot from the SD card to DMA mode such that the signal to the DAQ2 is routed from our model in the FPGA. I have been given (Travis) the following instruction:
Ok, so basically you need to set the data source of the TX interface core to DMA. This is done through the DAC_DDS_SEL registers: https://wiki.analog.com/resources/fpga/docs/axi_dac_ip
From iio_reg it would be: iio_reg axi-ad9144-hpc $((0x418 + i * 0x40)) 0x02
where i is the channel (0,1,2,3)
I have put the above in the init.sh file in the linux portion of the SD card in the /mnt folder.
It doesn't work.
What am I doing wrong please?
many thanks
Philip
