I am pleased to announce very fast boot for dm365.
It takes 0.5 (half of a second) from kernel initialization (not including u-boot and kernel unzip) till command line prompt.
Download ready uImage with root FS and test it: http://www.makelinux.net/ti/fastboot/
Boot time measured by printing /proc/uptime from boot script.
Solution:
- Linux kernel 2.6.18 from MontaVista Linux 5
- minimal kernel configuration with some source code tuning. Kernel configuration located in /proc/config.gz
- Root FS implemented with Busybox and connected as Init RAM FS and included in uImage. Busybox configuration located in /etc/busybox.config
Enjoy.
