Thank you for your additional information. As the steps followed are correct for the generated image we need to double check that XIP encryption is enabled on the corresponding GPIO. To check this make sure that the switches are configured like the last row:
Hi,
Im using MCUX to generate blinky example without changing root clock of M7:
Afterwards using SPT to generate image and load to hardware. On our hardware NOR Flash is connected to SPI1 2nd pingroup, so we've to add some options in boot memory configuration:
OTFAD configuration in SPT is done using default values and self generated certificate:
In given screenshot I've tried with OTFAD unsigend and "HAB open", but already tried with authenticated and HAB closed on other hardware but with same results.
OTP readout is here
I've also attached exported configuration as json file so you can see fuse settings.
Image generation and flashing is done without errors but afterwards CPU keeps booting into serial loader. When I try same procedure but with boot set to "unsigned" blinky example starts, so I don't think it's an issue with image itself oder NOR flash configuration.
According SRM it seems image loading fails:
But when I've a lock on the QSPI communication it stops reading after 300us just after IVT, so there is no access to encrypted image.
