imx6 ddr stress test

[chuanyanyin]

Hi:

When I run   DDR Stress Tester

D:\DDR_Stress_Tester_V1.0.2\DDR_Stress_Tester_V1.0.2\Binary>DDR_Stress_Tester.ex

e -t mx6x -df scripts\MX6_series_boards\SabreSD\RevC_and_RevB\MX6DQ\MX6Q_SabreSD

_DDR3_register_programming_aid_v1.5.inc

MX6DQ opened.

HAB_TYPE: DEVELOP

rom_write: reading HAB ack failed 0x00000000

ROM Write failed, addr: 0x020e0758

Write dcd failed.

why this happened? I run this script before, I never see this. my board is ott tvbox, and I can run the board with android

Please check boot mode setting . It should be internal boot mode or serial download mode.

  From the log we can see, that register IOMUXC_SW_PAD_CTL_GRP_DDRPK (at 0x020E_0758)
cannot be written via DCD table. Is it possible to check if it is possible to access this register

using a JTAG debugger or U-boot ?

Have a great day,
Yuri
