Revision as of 00:11, 30 March 2010

I am majoring in computer engineering and pursuing a certificate in optical communications. I am currently enrolled in ECE597, hoping to explore the applications of Linux in an embedded environment as well as the necessary considerations that must be made in developing for such an environment. I have a keen interest and a great deal of experience with Linux and am a member of the Rose-Hulman Linux Users' Group.

I am currently working on a script to automate the bitbake process with multiple cores. This is a copy of the script in its current form. Please note that it is a work in progress. 

#!/bin/sh
# bitbake automation
# J. Cody Collins

START=$(date +%s)

MAXTRIES=15
COUNT=1

export OETREE="${HOME}/oe"

echo "set environment variables"
. ${OETREE}/sourceme.txt 

echo "Go to the OE tree"
cd ${OETREE}/openembedded 

echo "Make sure it's up to date"
git pull --rebase

echo "Start building"
bitbake $1

while [ $? -ne 0 ]; do
	if [ $COUNT -lt $MAXTRIES ]; then
		((COUNT++))
		echo "re-running bitbake -- trial $COUNT"
		# Give the user a chance to kill the task
		sleep 5
		bitbake $1
	else
		echo "Maximum tries exceeded. Exiting..."
		break
	fi
done

END=$(date +%s)
DIFF=$(( $END - $START ))
echo "Build took $DIFF seconds."
echo "Completed after $COUNT attempts."

          Say Y, if you want to have a procfs entry for reading component
          versions (supplied by the bootloader) in user-space.

config OMAP_GPIO_SWITCH
        bool "GPIO switch support"
        default n
        help
          Say Y, if you want to have support for reporting of GPIO
          switches (e.g. cover switches) via sysfs. Your bootloader has
          to provide information about the switches to the kernel via the
          ATAG_BOARD mechanism if they're not defined by the board config.

config OMAP_MUX
        bool "OMAP multiplexing support"
        depends on ARCH_OMAP
        default y
        help
          Pin multiplexing support for OMAP boards. If your bootloader
          sets the multiplexing correctly, say N. Otherwise, or if unsure,
          say Y.

config OMAP_MUX_DEBUG
        bool "Multiplexing debug output"
        depends on OMAP_MUX
        help
          Makes the multiplexing functions print out a lot of debug info.
          This is useful if you want to find out the correct values of the
