    Hi Krishna,

    This issue is occurring because of a mismatch in the chip version in the setup.py script. For all AFE795x devices in setup.py chipVersion=0x13. For all AFE790x devices in setup.py chipVersion=0x20. 

    Please note that this issue is taken care of when using the respective AFE7900 or AFE7950 folders in the AFE79xx secure folder. We recommend using the scripts from the folder of the device you plan to use. 

    Regards,

    David Chaparro
