ad9361接收到的iq数据互换

这个图的下半部分是我用ila分别抓取DDR取出到dac发送的数据，上面的则是adc接收到的信号，这里看调制的qpsk是正常的

但是当我断电重启写入后，adc接收到的数据像是IQ两路的信号互换?

我用的是zc706和ad9361以及在no_os的基础上进行编码，主要修改了dac_core.c的初始化，用的是1R1T，调用的是DMA

gpio_init(GPIO_DEVICE_ID);
gpio_direction(default_init_param.gpio_resetb, 1);
spi_init(SPI_DEVICE_ID, 1, 0);

ad9361_init(&ad9361_phy, &default_init_param);
// AD9361 增益通常可达 70 dB 以上，我们设 70 dB 来充分放大信号。
// ad9361_set_rx_rf_gain(ad9361_phy, 0, 70); // 通道 0 (RX1), 增益 70 dB
ad9361_set_tx_fir_config(ad9361_phy, tx_fir_config);
ad9361_set_rx_fir_config(ad9361_phy, rx_fir_config);

// 1. 执行 TX 正交误差校准 (TX_QUAD_CAL)
// 用于修正 I/Q 信号的幅度和相位不平衡，arg 设为 0
ad9361_do_calib(ad9361_phy, TX_QUAD_CAL, 0);
ad9361_do_calib(ad9361_phy, RFDC_CAL, 0); //
printf("Calibrations complete.\n");
dac_init(ad9361_phy, DATA_SEL_DMA, 1);

mdelay(500);

dac_start_sync(ad9361_phy, 1); // 强制同步启动

mdelay(100); // 增加一个短延迟来等待同步完成
adc_init(ad9361_phy);

adc_capture(16384, ADC_DDR_BASEADDR);

Xil_DCacheInvalidateRange(ADC_DDR_BASEADDR,
ad9361_phy->pdata->rx2tx2 ? 16384 * 8 : 16384 * 4);
