Hi TI experts，

We want to collect ADC data through AWR2243BOOST+AM2732 EVM+DCA1000EVM, but after DCA1000EVM is connected to AM2732 for a period of time, about a few seconds (sometimes ten or twenty seconds), the EEPROM_RD_FAIL light of DCA1000 will be always on, at this time，there should be a problem with network communication between AM2732 and DCA1000, as shown in the figure below, but I have tried AWR2243+DCA1000 to collect ADC data directly through mmWave Studio. It is correct. The switching directions of S1 and S2 on AM2732EVM are consistent with the user guide. The switch settings of DCA1000EVM are as the second picture, please help to check where the problem may be, thank you.

    After I connect the DCA1000 to the AM2732 on my side, the NERR_OUT light will be on. This should indicate that there is still a problem with the hardware, but I have also checked that the hardware is consistent with the description in the userguide. It may be because of this reason that the DCA1000 EEPROM_RD_FAIL light will be turned on after a period of time. What are the possible factors that may cause the NERR_OUT light to turn on? thanks.
