I am using asdxl375 in one of my project.I am using SPI3 mode with 2Mhz clock.

 

1. Initially I have send DEV ID & correctly receive 0xE5 from device.

It means communication is OK.

 

2.But after that whatever I write & read back. The receive read data is always zero.

 

3. I have also tested voltage at Vio & Vs all are 3.3V, clean. Checked on 4 different boards none of them are working.

 

4. I have also checked on CRO step by step all data. Data sent is always Ok. But when data is read back after write its always zero. CS pin also ok.

 

5. Part of code is attached.
