We are working on a customized board based on iMX6Q sabre lite board. We are trying to initialize the DDR3 and unable to access it via JTAG.
We used the DDR Script Aid tool, generated script file for the MT41K256M16HA-125:E DDR3. When we ran the DDR_Stress_Tester_V1.0.3 tool, the stress tool was able to load the code in iRAM (Internal RAM) but after that, it couldn't continue the test.
The DDR_Stress_Tester reports the error message "Failed to reopen the device". We couldnt find much documentation about this error.
Please let me know if there is any documentation or any other way to initialize or Test the DDR3 RAM.
