Hello @alejandro_e ,
Thanks for the quick reply. The OMU App note and the corresponding demo helped me.
Overlay now works from RTU0 CRAM to RTU0 CRAM. However, I would like to overlay from the external flash (serial Hyperflash) to the RTU0 CRAM. The QSPI0 is connected to this onboard serial flash. Reading from the Flash via the AHB works fine.
As soon as a flash area is used for the logical or physical address in the OVERLAY_REGION, the overlay no longer works.
Question: Is an overlay even possible with the serial Hyperflash?
Setup:
S32Z270-DC
S32ZE Real Time Drivers AUTOSAR R21-11 Version 2.0.1
Thanks
Hello @jonas304,
I am glad the document I shared was useful. About using the serial hyper flash of the S32Z270-DC, my knowledge of the OMU module is very limited. However, I found an example internally that might help you. I will contact you privately and let you know how to access it.
Thanks
