i use ad9361 with no-os system at fmcomms2+zc706. and i select TDD mode to receive and transmit, use AGC mode.
after init setup, i do this
|uint32_t ensm_state ;|
|int16_t sampI, sampQ;|
for( i= 0; i< 16384; i++ )
rdata = Xil_In32(ADC_DDR_BASEADDR+(i*4));
sampQ = rdata & 0xFFFF;
sampI = (rdata>>16) & 0xFFFF;
now there is my question. after ENSM move to Rx, the red font "mdelay(10)" is need , and if the mdelay time is to less, the data i captured is no correct. but if i reduce the transmission power of the signal source to -60dbm(the init power is -20dbm), then delay 10 can be changed to 1.
i need a complete cycle time is less then 50us, I can change the other places delay, but the red font delay can't. what's my problem,and what can i do?
