Imx28 automount on any media

[shashikanthirem]

Hi all 

I did following

On ltib package list, choose:

device nodes (udev)

   [*] Include automount rules

   [*] Modify udev rules for non-raid systems

   [*] Include i.MX rules,

next build manually udev:

$./ltib -p udev -m prep

$./ltib -p udev -m scbuild

$./ltib -p udev -m scdeploy

copy the file  /rootfs/etc/udev/rules.d/65-automount.rules in your rootfs and reboot your board.

Also, in the automount files general rules are provided, that may be used as an example; please check

the rules if they are correct for Your configuration

I followed steps still,  the media connected to it is not auto mount, 

Still manual mount is required to see the content of  media devices

Any suggestions or input will be helpful

Found some more input

if i do SUBSYSTEM=block, then am not getting single udev event to process rules

here all the partitions device file there , but not processing the event

but if i give 

SUBSYSTEM=="mmc" then works, but i get host name mmc0:0001, here i need to manual unmount device file which is not good solution

what could be the reason...............?

More update

 if i do two times USB plug and unplug 

1st /dev/sda1 is getting mounted to /mnt/sda1

on unplug/ disconnect of USB, remains /mnt/sda1 folder remains same, ideally this has to be unmount and delete which is not happening

but on second time,  usb is 

/dev/sdb1 to  /mnt/sdb1

i beilieve remove is mot working

this is my auto generated udev rules from ltib

ACTION=="remove", KERNEL=="sd[a-z]*", RUN+="/bin/umount -l /mnt/%k"
ACTION=="remove", KERNEL=="sd[a-z]*", RUN+="/bin/rmdir /mnt/%k", OPTIONS="last_rule"

Hello Shashikant H,

Thank you for sharing your findings. The procedure looks okay in general terms, although LTIB is no longer supported and it’s not easy to troubleshoot in modern Ubuntu releases.

Hopefully other community users may be able to provide some help.

My apologies for the inconvenience.

Regards,

[shashikanthirem]

then could you please tell, why its a part of package list populated in ltib , i believe  remove usb should work,

do i need to work on udev rules ?

does anyone face this problem..

these are my udev events on remove sdcard mmcblk0
