TDA2EXEVM: MIMO Use Case: Enabling Only Slave 2, and 8 Failed

Part Number: TDA2EXEVM

Hi,

We tried to disable the 2 left AWR on the Cascade RF Board and only enable Slave device 2, and 8 (2 right most) for receive. We also disabled all AWR TXes but 1 on the Master. So Master will transmit a single chirp on TX0 and Slave 2 and 8 receive on their RXes. We disabled rx channals by setting rfChanCfgArgs.rxChannelEn & dataFmtCfgArgs.rxChannelEn to 0 in file chains_common_cascade_ar12xx_config.c. However, we got the following error when run the code:

GT_0trace(VpsDrvCaptTrace, GT_ERR,
"Core control: Set Max Frame Size failed!!\r\n");

Please advice...

Thanks,
