    Hi Jeff,

    As this is an NDA device I typically can't help on the open boards. To try and help you anyway. Yest the device will output VDD6 without a SPI command, the device should still work without a signal on WDI/ERROR unless that has been enabled on SPI. I am not entirely sure what you are probing but I have seen have been due to poor GND connections. Please look at the EVM schematic and layout for this device in the secure folder. Please reach out to your local TI representative and once they make sure all of the NDA's are in place they can connect us directly over email, or use the internal forums which I can post more information.

    Best,

    Michael Hernandez
