4.14.2. Enabling Simple Memory Test

After the SDRAM is successfully calibrated, a simple memory test may be performed using the debugger.
  1. When you create the .bsp file in the BSP Editor, select HARDWARE_DIAGNOSTIC in the spl.debug window.

  2. The simple memory test assumes SDRAM with a memory size of 1 GB. If your board contains a different SDRAM memory size, open the file <design folder>\spl_bsp\uboot-socfpga\include\configs\socfpga_cyclone5.h in a text editor, and change the PHYS_SDRAM_1_SIZE parameter at line 292 to specify your actual memory size in bytes.
