Thanks for the hint! That would be understandable, but I would at least be expecting to have some error messages. But I do not get any - the board just does not pass SPL at all, as like SEC0 hangs during RNG instantiation (my rough speculations here). > Does the board boot with IMX_HAB=y with NXP TF-A? Nope, unfortunately also not. Once HAB config is enabled on the i.MX8MP - the board does not pass the SPL, even with NXP TF-A. > > Regards, > > Fabio Estevam -- andrey
