How to integrate a new QSPI Flash with RZ/A1 LU

Hi,

We are trying to integrate the QSPI flash SST26 from microchip (http://ww1.microchip.com/downloads/en/devicedoc/20005218e.pdf) on our custom board based on the stream it architecture with RZ/A1 LU.

I am using the SDK of stream it with CMSIS-RTOS. My program run in RAM but I am trying to use QSPI loader sample  

We are stuck in this adress (See image below). When I check the memory map I see FFFFFFF on 0x18000000.

Any idea to solve my issue ?

Thanks for you reply.
