    Thread Summary
    
                The user encountered issues with the SPI EEPROM access example on the EV-SC598-SOM+EV-SOMCRR-EZKIT (rev.D) with board package version 3.0.2. The problem was resolved by changing the value from 0xDA to 0x3A in the ConfigSoftSwitches_EV_SOMCRR_EZKIT.c file, confirming that ~EEPROM_EN was correctly set to 0. The user is using BSP version 3.2.0.

    Hi,
    

    I am using EV-SC598-SOM+EV-SOMCRR-EZKIT, both are rev.D.
    

    The board package is version 3.0.2.
    

    

    I am interested in the spi eeprom access example.
    

    Unfortunately, it failed consistently. With debugging, I can see the write data is rand() while the read data is all 0xFF.
    

    

    Is there something I am missing? Please advise. Thank you.

      Hi Sophion,
      

      Can you check and confirm whether ~EEPROM_EN is configured as 0 in the ConfigSoftSwitches_EV_SOMCRR_EZKIT.c file? If not, please update it accordingly and share the outcome.
      

      If you're still facing issues, please share the project so we can check it further.
      

      Regards,
      Nandini C

        Hi Nandini,
        

        Thank you for your reply.
        ~EEPROM_EN is configured as 0. However, your guidance made me to double check the values.

        

         
        

        After changing the value from 0xDA to 0x3A, the SPI EEPROM access example passed the write/read check.
        

        Hence, the comments is correct while the value is wrong.
        

        I am using BSP ver3.2.0.
        

        Again, thank you very much for the swift support. Highly appreciated. ;)
        

        Wish a lovely day.
