Hi Kenny,

If you are using PSDKLA on DRA7x, EVE can not be loaded, only vision SDK software can load EVE.

What is the software stack being used ?

Running the default app from vision SDK should show if EVE is loaded.

Thanks

Hi Ramprasad:

I am using PROCESSOR SDK, but IPU firmware is built from vision sdk

Should I run the default app to see the status of EVE on my platform?

Thank you

Kenny

There is no application is Processor SDK to invoke EVE . You will have to use vision-sdk Linux, and the default app in vision-sdk linux to run a usecase which uses EVE

Hi Ramprasad:
Thanks for your reply
Let me explain more
Our customer ask us to "enable" EVE core, no need to run an application to use it
So my job is bring up EVE and run at 650 MHz
Because as i know the process when IPU bring up EVE there is no debug msg to show
I have no idea how can i know EVE is enabled or not
Do you know any method to check EVE status?
thanks

Hi Kenny,
There is no option from A15/Linux to know the status of EVE since it is loaded and controlled by M4 firmwares.
There is no sysfs entry possible for EVE to know the status
