I am using KC705 with FMCOMMS4 (AD9364) with HDL ref. design Vivado2014.4.1 and last version of noOS driver.
I have a question regarding tx_frame signal that remains high at the given test point on the FMCOMMS4. I am using the default parameters (default_init_param structure) settings in main.c (attached herewith) except that two_rx_two_tx_mode_enable is set to zero because I have AD9364.
According to UG673 (reference manual) pg 102 fig 76, I was expecting the following behaviour,
where tx_frame is 50% duty cycle. However, I found that tx_frame is always high.
I found on pg 99 of UG673 the following
"Tx_FRAME can accept a single high transition at the beginning of a burst that stays high throughout the burst or a pulse train that has a rising edge at the beginning of each frame (50% duty cycle)."
so, I suppose that with the default parameters setting of main.c the FMCOMMS4 is in burst mode.
If it is so, does it have any relation with rx_frame_pulse_mode_enable parameters in default_init_param structure in main.c?
Could you please help us in order to change from burst mode to continuous mode?
Thanks in advance.
