[Ltib] USB automount and auto-run on LTIB?

[kevin.huang]

Hi,

 

I’m working on a NXP LPC3131x board running LTIB. I’m trying to get some sort of auto-mount/run going when I plug in a USB pendrive into the board. So far I believe the way to do this is by utilizing Udev and configuring it so that it automatically runs shell commands when the USB drive is mounted or detected.

 

I noticed that the udev package was not available for selection in the normal configuration menu (./ltib –config) but I was able to prep the package by using ./ltib –p udev and adjusting one of the configuration files to pass the changes through. However I think the boot process is still not utilizing udev despite my “installation”. I’m still learning about USB and the boot process with Linux, so I think currently my LTIB Linux kernel is simply loading usbfs or some other USB driver that has nothing to do with my udev configuration.

 

Am I going about this the right way? Any pointers/directions on where I should focus my efforts would be greatly appreciated. Below is the output when I get the board to boot. I don’t see any mention of udev anywhere.

 

Thank you,

Kevin Huang
