These are detailed programming aids for the registers associated with DRAM initialization (LPDDR3, DDR3, and LPDDR2). The last work sheet tab in the tool formats the register settings for use with the ARM DS5 debugger. It can also be used with the windows executable for the DDR Stress Test (note the removal of debugger specific commands in this tab). These programming aids were developed for internal NXP validation boards.
This tool serves as an aid to assist with programming the DDR interface of the MX7D and is based on the DDR initialization scripts developed for NXP boards and no guarantees are made by this tool.
The following are some general notes regarding this tool:
