AWR1243: Complex2X mode

TG2718

Part Number: AWR1243

I attempted to configure the AWR1243 chip to Complex2X mode to investigate possible interference. I am using Processor SDK Vision 3.3. For the configuration, I set rlAdcBitFormat.b2AdcOutFmt and rlDevDataFmtCfg.adcFmt to 2. However, I received an error on the UART console: [ERR ] rlDriverMsgCmdReply:820::AWR1243 Error msg: 1003. According to the interface control document, error 1003 means ADC_OUT_FMT > 1. No data is acquired in this case, either.

What do I need to do to get Complex2X mode to work?

Thanks.

Hi,

You can keep rlDevDataFmtCfg.adcFmt to 1. This is only CSI2/LVDS data format which is Real or complex.

You need to change rlAdcOutCfg_t.fmt.b2AdcOutFmt to 2 for Complex 2x

Your solution solved the problem. Please note that the AWR1xxx interface control document (rev 0.95) information on this field (section 10.6.47) appears to indicate that adcFmt should be set to 2 for Complex2x, despite the fact that does not appear to work.

Thanks!
