imx6 solo kernel boot failed（CSI camera issue）

[昌清黄]

Hi all：

          The hardware board is our own development。（imx6 solo）

          BSP ：L3.0.101_4.1.1。 kernel defconfig：imx6s_defconfig

        the project source code have not modified。

          I compile the project after starting system：

how can i do?

[igorpadykov]

Hi 昌清

what is memory capacity on your board, had DDR tests

run OK  ?

Best regards

igor

[昌清黄]

Hi igorpadykov:

          my board memory capacity: 512M.

                         DDR chip: MT41K128M16JT

                         DDR chip total number: 2

                         data bus width: 32

     when excute Read DQS Gating, but system information showed the result failed，

what causes this issue？

[igorpadykov]

Hi 昌清

if you board runs other memory tests well, you can omit

DQS Gating. In particular this issue may be caused by board noise.

Best regards

igor

[昌清黄]

hi igor：

    Stress Test failed

[igorpadykov]

suggest to run SDK (it has simple DDR test)

i.MX 6Series Platform SDK

and check this error, it means

data 0x10000000 was written on address 0x10000000

but back read 0.

You can check that with jtag, probably data line is broken or shorted.

hi igor：

        i.MX6_DDR_Stress_Tester_User_Guide.pdf

      “DDR_ Stress_Tester -t mx6x -df mx6x_ddr_script_filename”

       The mx6x_ddr_script_filename must be manually configured ？

        Can use tool to generate script？ such as I.MX6DQSDL DDR3 Script Aid V0.10.xlsx？

       But I.MX6DQSDL DDR3 Script Aid V0.10.xlsx  is just a file
