AWR2243: chirp error when enabling 2 TX chirps per framce

Part Number: AWR2243

Dear TI Support,

We are configuring the AWR2243 over SPI and get the following error when we increase the number of chirps from 1 to 2 TX chirps per frame.

The config A for 1 TX chirp in 'spi0.dev0.0.normal.log.txt' works correctly

And the config B for 2 TX chirps in spi0.dev0.0.log.cpufault20221219.txt gives the following error:

Device EVENT ID = 5002 (len=32) AWR_AE_MSS_CPUFAULT_SB
FAULT_TYPE = 4(0x4)

In config B the chirp cycle time = 80us, there are 2 chirps per frame and the frame period is 1.00016 sec.  

The following word file 'diff20221219.docx' shows the changes between the two configs A -> B.

So would you be able to advise on what might be causing this error?

Yours faithfully,

Jonathan
