TPS65987D: is it possible to use default configuration when flash is invalid OR boot from flash when it was already programmed?

Part Number: TPS65987D

Hi all,

I have a question to

Now I have TPS65987EVM and I solded 3,3K pulldown to the MISO and solded out the R46 PullUp on EVM. And EVM always boots the default configuration. Also for valid flash content. Is this ok? It is pretty difficult to interpret the boot sequence on P.12 at

My question is: is it possible to use default configuration1 when flash is invalid OR boot from flash when it was already programmed? What we need to implement in HW for this case?

Thanks,

Sergey

Hello,

If you do not use the default configurations, and want your own custom flash image, you will need to use the application configuration tool to create an image that you will either program to the PD controller via external SPI flash or an external EC. The app not you linked is for an external EC application.

You can use the following link to help get you started in using the configuration tool
