ADS1261EVM: Write failed on ADS1262EVM when using Delta-Sigma ADC EvaluaTIon Software

HI All,

I am using the ADS1261EVM (ADS1262) with the evaluation software, and finding whether I am using a predefined or user defined (goal the latter) software that I am consistently getting a "write failed" error.

I have tested whether the script starts or ends with the RESET command, no change.

Below is my XML user defined script, a photo of my board (which itself is connected to Bridgestone arrangement of four generic 50kg 0.1 kg mV/V sensitivity scales).

Is this a sign of my misunderstanding on the use of the software/hardware configuration - or is it likely that my software/MCU is not working correctly?
