AWR1642BOOST: SDK 2.x vs SDK 3.6 datapath difference

AWR1642BOOST: Porting 1642 High Accuracy from SDK 2.x to SDK 3.x - continue

Thank TI Engineer you for supporting so far on previous thread.

I would like to ask some question regarding our effort porting High Accuracy xWR1642 from SDK 2.x to 3.x.

I got source code xWR1843 High Accuracy and I can compiled it well with some porting params settled.

But I need to debug more, because I found error : 

"MWDSS Error : to open the ADCBUF driver" which seems comes from MmwDemo_dataPathAdcBufInit() in dss_main.c.

This problem lead me to this : https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/866855/awr1843boost-error-mmwdemodss-unable-to-open-the-adcbuf-driver

which said , " ... need to do this experiment with same version to verify. Or do the stepping in the code/library to get know the breaking point in the application."

Question#1 : I use SDK 3.x as mention above.

is this related with sys bios, XCD tools version ?

I tried different version Sys Bios 6.53 and 6.73 but still same result. XCD tools that provide for both SDK 2.x and 3.X seems didn't resolve this problem

Question#2 : Actually,  I only need to add calibration CLI on ( sample is on Out of Box Demo SDK 3.x) to 1642 High Accuracy.

Should I keep porting High Accuracy SDK to SDK 3.x to

Question#3 : AWR1642BOOST-ODS that I'm using right now has patch antenna which is has 1 TX 1RX. This is suffice for High Accuracy application , correct ?

Thank you

    Hi,

    Using mmWave SDK 2.1.0.4, the 16xx High Accuracy Lab should build without error. The error related to the ADCBUF driver is likely due to changes between SDK 2.x and 3.x, but it is hard to say for sure without debugging further. If you are looking to just add the calibration related CLI items, it may be easier for you to migrate that code back to SDK 2.1.0.4 rather than porting the entire demo to SDK 3.x. Since the High Accuracy Level Sensing demo only uses 1TX antenna and 1RX antenna, any of the TI evaluation modules should be sufficient. You can experiment with different pairs of antennas to determine which gives you the most accurate results for your specific antenna. 

    Best Regards,
    Alec
