AWR1642: ADC buffer size

Part Number: AWR1642

Hello everyone

As showing in the AWR Technical reference manual, 16xx has 32KB ADC buffer, so which means it can stores up to 32K/4Ch/4 Byte IQ = 2K samples. However, everytime when I sample more than 1K point, the code would give me the error.(error code -13008--MMWAVE_EPROFILECFG) I am running the mmWave demo, 1Tx 4Rx.

Can you tell me why?

Regards
