iMX6Q: Cores run into deadlock

Hi,

 

I am having an issue running bare-metal RTOS on iMX6Q: 5 out of 10 times I boot it up one or more cores stop working but never core 0.

I did implement all errata I found or even relying on barebox does not help.

After a certain point in the application (or some time ?) no more deadlock happens.

 

Is there an issue (not yet documented in an erratum) with the booting of the other cores?

Do I need to start the other cores one by one with delay?

 

Can anyone shed some light on this?

 

And no: I do not use Linux/Android!
