| + | If you want to extract the config file from existing linux image, zImage or bzImage, do the following (only applies if was built with the IKCONFIG option): | ||
| + | Download the files with the linux sources: | ||
| + | |||
| + | <code> | ||
| + | cd | ||
| + | |||
| + | mkdir krn | ||
| + | |||
| + | cd krn/ | ||
| + | |||
| + | wget ftp://ftp.embeddedarm.com/ts-arm-sbc/ts-7260-linux/sources/tskernel-2.6.21-ts-src.tar.gz | ||
| + | </code> | ||
| + | |||
| + | Unpack the linux kernel sources: | ||
| + | |||
| + | <code> | ||
| + | tar xvfz tskernel-2.6.21-ts-src.tar.gz | ||
| + | </code> | ||
| + | |||
| + | Go into the directory of the kernel sources: | ||
| + | |||
| + | <code> | ||
| + | cd linux-2.6.21-ts/ | ||
| + | </code> | ||
| + | |||
| + | Type: | ||
| + | |||
| + | <code> | ||
| + | chmod 755 ./scripts/extract-ikconfig | ||
| + | </code> | ||
| + | |||
| + | Run: | ||
| + | |||
| + | <code> | ||
| + | ./scripts/extract-ikconfig /tmp/zImage > /tmp/config | ||
| + | </code> | ||
| + | |||
| + | Where /tmp/zImage is a kernel file you want to extract the config file from, and /tmp/config where the extracted configuration file will be placed. | ||
