I am using custom imx6qp board with DDR chip MT41K1G16. I am using JTAG to run DDR stress test v2.60 tool on imx6qp. I am using file ddr-test-uboot-jtag-mx6dq.elf. Stress test tool is able to start, it hangs after some time while doing calibration. It shows BOOT_CFG[5:4] = 0x03. Invalid DDR map. Below is the log from DDR stress test tool

 

============================================
        DDR Stress Test (2.6.0)
        Build: Oct 24 2016, 15:21:46
        NXP Semiconductors.
============================================

 

============================================
        Chip ID
CHIP ID = i.MX6 Dual/Quad (0x63)
Internal Revision = TO2.0
============================================

 

============================================
        Boot Configuration
SRC_SBMR1(0x020d8004) = 0xf7ff575e
SRC_SBMR2(0x020d801c) = 0x11000001
============================================

 

What ARM core speed would you like to run?
Type 1 for 800MHz, 2 for 1GHz, 3 for 1.2GHz 
ARM Clock set to 1GHz

 

============================================
        DDR configuration
BOOT_CFG3[5-4]: 0x03, Invalid DDR map.
DDR type is DDR3
Data width: 64, bank num: 8
Row size: 16, col size: 10
Chip select CSD0 is used
Density per chip select: 4096MB

 

What is the reason for showing Invalid DDR map??
