Hi! I'm trying to bring up a custom imx6q board using JTAG, because it has only NAND for booting and no SD connector attached. The design has imx6q and two DDR3 chips (MT41J256M16HA-125:E) populated. First of all I try to use the DDR stress test tool v2.40 to test and calibrate DDR3 memory. The test I took from here: i.MX6/7 DDR Stress Test Tool V2.40 It starts, I can choose options but then it hangs. I don't know why and where in the code. I don't the sources. ============================================         DDR Stress Test (2.4.0)         Build: Dec 11 2015, 11:09:30         Freescale Semiconductor, Inc. ============================================ ============================================         Chip ID CHIP ID = i.MX6 Dual/Quad (0x63) Internal Revision = TO1.5 ============================================ ============================================         Boot Configuration SRC_SBMR1(0x020d8004) = 0x00003050 SRC_SBMR2(0x020d801c) = 0x22000001 ============================================ 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]: 0x00, Single DDR channel. DDR type is DDR3 Data width: 32, bank num: 8 Row size: 14, col size: 10 No chip select is enabled Density per chip select: 512MB ============================================ Current Tempareture: 31 ============================================ Please select the DDR density per chip select (in bytes) on the board Type 0 for 2GB; 1 for 1GB; 2 for 512MB; 3 for 256MB; 4 for 128MB; 5 for 64MB; 6 for 32MB For maximum supported density (4GB), we can only access up to 3.75GB.  Type 7 to select this   DDR density selected (MB): 512 Would do you want run DDR Calibration? Type 'y' to run and 'n' to skip Calibration will run at DDR frequency 528MHz. Type 'y' to continue. If you want to run at other DDR frequency. Type 'n' Enter the DDR frequency for calibration [350MHz to 528MHz]: 350   The freq you entered was: 350   Please enter the MR1 value on the initilization script   This will be re-programmed into MR1 after write leveling calibration   Enter as a 4-digit HEX value, example 0004, then hit enter 0004DDR Freq: 352 MHz ddr_mr1=0x00000004 Start write leveling calibration... running Write level HW calibration Write leveling calibration completed, update the following registers in your initialization script     MMDC_MPWLDECTRL0 ch0 (0x021b080c) = 0x00010001     MMDC_MPWLDECTRL1 ch0 (0x021b0810) = 0x00010001 Write DQS delay result:    Write DQS0 delay: 1/256 CK    Write DQS1 delay: 1/256 CK    Write DQS2 delay: 1/256 CK    Write DQS3 delay: 1/256 CK Please suggest what to do next ...
