How can I access the full SDRAM memory space on my Intel® Stratix® 10 SX device?


Due to a problem in uboot-socfpga, it is not possible to access a physical 2GB portion of the SDRAM (2GB-4GB address range).  This can cause errors in u-boot / Linux for system with above 2GB of SDRAM installed, if this physical memory area checked or accessed. 



This problem is scheduled to be fixed in a future release of u-boot-socfpga.

A patch is also available to address this problem,  please submit a Support Case  or contact your FAE for access to the patch.
