Dear Team ,

As asked , i had created an fresh oe-core setup again ( just to give team confidence that the steps are proper).
But the problem still remains .

For the suggestion to try with IMAGE_INSTALL_remove = “firefox”,

ERROR: ParseError at /home/ashish/oe-core/build/conf/local.conf:277: unparsed line: ‘IMAGE_INSTALL_remove = “firefox”’

Could team members look at this , we can proceed when without the firefox require

Attached is the log for the same . link text

Hi

It looks like some well meaning web editor did change the " to some more presentable UTF-8 character.
Can you type the " on your keyboard instead of copy/pasting them?

E.g. when searching for " in your log the layer git hashes show up, but the “firefox” does not.

Dear Max ,

  1. Thanks for the pointer , the log.conf ParseError is cleared.

  2. The bitbake -k angstrom-lxde-image returns error log similar to

ERROR: When reparsing /home/ashish/oe-core/build/…/layers/meta-toradex-demos/recipes-images/images/angstrom-lxde-image.bb.do_imagedeploy, the basehash value changed from 0078ec97ca45cec1c69ef31cb8d52407 to 2075a650bc98ae7d95be44ab91f39d31. The metadata is not deterministic and this needs to be fixed.

Can you please share any pointer as to the probable reason of it.
Attached along is the log link text

I am planning to add an hello_world project and verify the sanity.

Can you remove sstate-cache in build directory and give build command again?

27

Is there any suggested way of doing it or i can delete the corresponding folder
( #SSTATE_DIR ?= “${TOPDIR}/sstate-cache” ) manually .

28

Just

rm -rf sstate-cache

Please do not touch the conf file for this. sstate-cache is in the build directory.

[mas@linuxdev build]$ ls
bitbake.lock  buildhistory  cache  conf  downloads  sstate-cache  tmp-glibc

  1. I tried after removing the sstate-cache folder as suggested.

With this, the "basehash value changed " is not thrown on the console at the first iteration. Without doing anything if i ran the bitbake -k angstrom-lxde-image again , i start getting the error log as mentioned above.

  1. W.r.t the flashing the image created on the SOM as per steps mentioned Flashing Embedded Linux to iMX6 Modules

i am not getting the update_it command .
Below is the log from uboot command prompt

Apalis iMX6 # run update_it

Error: “update_it” not defined

Apalis iMX6 # run update<<PRESSED TAB TO SEE THE OPTIONS >>

update update_1 update_2 update_3 update_configblock update_fdt update_kernel update_latest update_new update_spl update_to_spl update_uboot update_uboot_bin update_v2.4b1 update_v2.5b3

Adding the log for reference [link text][1]

  1. If i try ahead with run update instead of run update_it , i get
    EXT4-fs (mmcblk0p2): resized filesystem to on console

Hi All ,
Adding an brief summary for helping other in case some one face similar issue :-

[ 27.442270] mxc_sdc_fb fb.20: 640x480 h_sync,r,l: 96,16,48 v_sync,l,u: 2,10,33 pixclock=25200000 Hz was the initial problem we faced & with below mentioned pointers from Toradex team we can at-least proceed ahead

  1. Try repo init -u Index of /toradex-bsp-platform.git -b LinuxImageV2.7
    insted of repo init -u Index of /toradex-bsp-platform.git -b LinuxImageV2.6.1

  2. The above will fail with messages pointing towards FIREFOX package .
    Hence try IMAGE_INSTALL_remove = “firefox”

  3. For the bitbake command you would get an below mentioned error
    …/oe-core/build/…/layers/meta-toradex-demos/recipes-images/images/angstrom-lxde-image.bb.do_imagedeploy, the basehash value changed from 0078ec97ca45cec1c69ef31cb8d52407 to 2075a650bc98ae7d95be44ab91f39d31. The metadata is not deterministic and this needs to be fixed.

You can remove the SSTATE_DIR folder & clean build it again.

  1. For flashing from SD card there is not "update_it " command supported.
    Hence proceed ahead with "run update "

  2. If flashing is proper we get error similar to
    [ 39.619012] EXT4-fs (mmcblk0p2): resized filesystem to 1604608
    This is observed only on the first time , i wasn’t aware of this .

  3. Also try not to use the HDMI to VGA converter.

Thanks to Max , Sanchayan , Manoj from toradex to helping & providing valuable inputs .
