Only 16K of 8M PSRAM accessible on B-U585I-IOT02A

[Marty]

I'm using a B-U585I-IOT02A board and the IOT_HTTP_WebServer example code. 

My read is the PSRAM is 8M on that board, but I can only access 16K (to 0x2803ffff) and then ???? is not IDE memory display or a trap in the code.  Is this a CPU configuration issue?

Hello @Marty ;

 

Could you please check the device size?

hospi1.Init.DeviceSize = 23;

 

Also, I recommend you to look at OSPI_PSRAM_MemoryMapped example and check the OCTOSPI configuration.

 

Thank you.
