IMX6SL kernel hang, linux kernel(3.0.35)

[sailfish009]

hi

     imx6sl use L3.0.35_4.1.0_130816 to build u-boot,kernel and rootfs.  when system hang-up during booting. it happen always.

    here is the kernel log:

Hi Ji

had you updated DDR settings for custom board with results of DDR tool below

(uboot/board/freescale/mx6sl_evk/flash_header.S) ?

i.MX6 DDR Stress Test Tool V1.0.3

Also one can try various kernel boot parameters, given in attached

document, Table 7. Kernel Boot Parameters: such as ip=none

and others.

Best regards

igor

[sailfish009]

it turned out, built bsp image was wrong in some linux environment,

when i build linux kernel in ltib-build-package(with custom emmc patch) from freescale official site, it didn't worked.

uImage size is 3.4MB

i.MX 6SoloLite Evaluation Kit|Freescale

so, i received ltib-build-package(with custom emmc patch) for i.MX6SL  from freescale technical support company in my area.

built the package with no-distclean configuration, it boot without hang-up.

uImage size is 3.3MB

--

PS:

1. tested linux environment were ubuntu 9.04 32bit, 11.04 64bit, 12.04 64bit

2. tried linux kernel 3.0.101 patch set, also didn't worked.

[igorpadykov]

probably DDR settings were different in these two

cases: one accidentally works for you, another  - not.

[sailfish009]

not sure, because if i did "make ARCH=arm CROSS_COMPILE=... distclean" in working ltib-build-package.

and build it again "ltib -m scbuild -p kernel", uImage also didn't worked. 3.3MB(O) -> 3.4MB(X)

[igorpadykov]

DDR settings are not defined in kernel, they are defined

in uboot dcd header.

[sailfish009 · Accepted solution]

Thanks, this is very helpful, especially for Yocto version!

i.Mx6SL LPDDR2 Script Aid

PS: [2014-12-20]

i found that real reason that hangs,

my board is customized which is come with 8GB emmc.

and official LTIB build kernel configuration file is NOT worked for my board,

i found out that freescsale FAE company's linux kernel configuration file is different

from freescale legacy LTIB kernel configuration file!!

THE freescsale FAE company's linux kernel configuration file is worked for my board.

[sailfish009]

Hi, igor!

no i didn't, so i have tried your suggestion, but,

page 7/23 in i.MX6_DDR_Stress_Tester_User_Guide.pdf.

BOOT_CFG3[5:4] is reserved value, how to check the value?

and stress test result hang-up at first trial in my board.

in reference board, the stress test works fine.

DDR_Stress_Tester.exe -t mx6x -

df scripts\MX6_series_boards\MX6SL_Megrez_boards\MX6SL_MMDC_LPDDR2_register_prog

ramming_aid_v0.9.inc

Would you like to run the DDR Stress Test (y/n)?

Enter desired START freq (135 to 672 MHz), then hit enter.

Note: DDR3 minimum is ~333MHz, do not recommend to go too much below this.

135

  The freq you entered was: 135

Enter desired END freq (135 to 672 MHz), then hit enter.

Make sure this is equal to or greater than start freq

300

  The freq you entered was: 300

Beginning stress test

loop: 1

[igorpadykov]

Hi Ji

fuses can be read with below

https://community.freescale.com/docs/DOC-95458

BOOT_CFG3[5-4] configure the lpddr2 mapping mode

'00' Single channel

‘01’ for “Fixed 2x32 map”

'10’ for “4KB interleaving” mode

also please create new thread and provide

more details about you board configuration:

proccesor full name and what DDR memory was used.

Best regards
