Hi Josue,

Thank you very much.

Below FAQ only mentions about "OSPI", customer wants to know if "QSPI" support XIP execution, too. Is the QSPI same to OSPI?

XIP

This use case (short for eXecute-In-Place) involves a core directly executing code from the flash instead of first loading into internal memory. There aren't many restrictions in this usecase since this will likely happen in a custom application.Depending on the software environment you may need to write/add in custom code to configure the flash for XIP and configure any core's MMU/MPU to have the OSPI memory region as executable (and recommend cacheable as well for applicable cores, this will increase performance and allow cache-line fetches).

Thanks
Regards

Hi Shine,

I don't think this will be the case based this entry from the TRM:
