Kernel Panic Issue on i.MX6 based Custom Board

[hrushinale]

Hello Everyone,

I am working on i.MX6 based custom board .I am using u-boot version 2014.04 and kernel version 3.14.28 from freescale.I have done the driver Integration for all I/O's which are available on our board.Now my problem is when I am booting the board 10 out of 6 times I am getting the kernel panic or stucking at some point.I am unable to understand why I am getting this issue.

Problem#1: Kernel Panic with below logs

Hi Hrushi

this behaviour may be caused by ddr faults, please run ddr test

i.MX6/7 DDR Stress Test Tool V2.52 | NXP Community

and rebuild uboot (change *.cfg file) with new calibration settings found from test

Please use nxp bsp releases from

i.MX 6 Series Software and Development Tool|NXP

Best regards

igor

Hi igorpadykov,

I followed the I.MX6DQSDL DDR3 Script Aid V0.10 document. In this document I entered the Values as per our DDR part number MT41K256M16TW-107 from Micron.

• But When we are going to start the DDr calibration its showing "DCD ADDRESS OUT OF RANGE"

Kindly help Regarding this issue.

Thanks & Regards,

Hrushi

[aravinthkumarja]

HI hrushinale​,

After filling the values, you open RealView.inc sheet in same excel sheet. There you will get the updated DDR value.

Then this value you need to update in you ddr application .inc file.

Then you try.

If again it shows error, Can you mention what steps you followed??

Regards,

Aravinth

[hrushinale]

Hello aravinth,

I followed the same steps:

1) First I enter the Values in Excel sheet as per our DDR Part number.

2)then updated the values I got to .inc file

3) Then start the DDr calibration

but still Its giving the same error
