ADS7038-Q1: Unable to establish communication with ADS7038 from TI controller F29H85X-SOM-EVM

Hi Team

   Need an urgent support to establish establish communication with ADS7038 from TI controller F29H85X-SOM-EVM. We are always receiveing a value "2" or "1" for any given transmission request(write or read)

We verified the following on ADS7038 chip:

Supply to ADS is 5V in AVDD and DVDD

Trying to establish communication with example code of TI SPI_ex5_ext_loopback_dma with following modificaitons in code

1. Removed loopback
2. Changed Pins for SPI
3. Transfer size adapted for ADS7038
4. Rx DMA is configured
5. Trying to read SYSTEM_STATUS register from ADS7038 and trying to write 1 in FIX_PAT to receive A5A pattern in DATA_CFG register for testing purpose

Attached below

1. code: spi_ex5_loopback_dma.c 

2. configuration in txt format spi_ex5_loopback_dma_ADS7038_syscfg.txt 

3. snippet of the picoscope.

Thanks and regards
