Category: Software
Software Version: 2021R1
I'm using ADRV9364 board with BOB carrier. I'm using 2021 R1 hdl and no-os code.
I'm testing ADC_DMA_EXAMPLE and DAC_DMA_EXAMPLE.
My app_config.h looks like this:
#ifndef CONFIG_H_ #define CONFIG_H_ #define HAVE_SPLIT_GAIN_TABLE 1 /* only set to 0 in case split_gain_table_mode_enable = 0*/ #define HAVE_TDD_SYNTH_TABLE 1 /* only set to 0 in case split_gain_table_mode_enable = 0*/ #define AD9361_DEVICE 0 /* set it 1 if AD9361 device is used, 0 otherwise */ #define AD9364_DEVICE 1 /* set it 1 if AD9364 device is used, 0 otherwise */ #define AD9363A_DEVICE 0 /* set it 1 if AD9363A device is used, 0 otherwise */ #define XILINX_PLATFORM //#define ALTERA_PLATFORM //#define LINUX_PLATFORM //#define FMCOMMS5 #define ADI_RF_SOM //#define ADI_RF_SOM_CMOS #define ADC_DMA_EXAMPLE #define ADC_DMA_IRQ_EXAMPLE #define DAC_DMA_EXAMPLE //#define AXI_ADC_NOT_PRESENT //#define TDD_SWITCH_STATE_EXAMPLE //#define IIO_SUPPORT #ifndef IIO_SUPPORT #define HAVE_VERBOSE_MESSAGES /* Recommended during development prints errors and warnings */ //#define HAVE_DEBUG_MESSAGES /* For Debug purposes only */ #endif // USE_LIBIIO /* * In case memory footprint is a concern these options allow * to disable unused functionality which may free up a few kb */ #endif

After I run the code, console output is:
cf-ad9361-lpc: Successfully initialized (61439514 Hz) ad9361_init : AD936x Rev 2 successfully initialized cf-ad9361-dds-core-lpc: Successfully initialized (61439514 Hz) cf-ad9361-lpc: Successfully initialized (61441040 Hz) DAC_DMA_EXAMPLE: address=0x13d030 samples=32768 channels=2 bits=16 Done.
Why I'm getting 32768 samples instead of 16384 specified in parameters.h (#define ADC_BUFFER_SAMPLES 16384)?
When I look memory content, tx looks as expected:
The period is 128 samples as expected.
When I look rx memory, I will see:
As we can see, period is 256 samples, which is not correct. When I look data closer, it has strange ripple:
What might cause this issue?
