Our development environment also uses NFS root filesystem & we use u- boot to load the kernel Image.
The average boot time on OMAP 3430 with Android 1.6 SDK is 1 min 18 sec. The average boot time on OMAP 3430 with Android 2.1 SDK is 1 min 30 sec. We are also trying to explore areas of booting phase other than 1. Pre loading & 2. Scanning for boot time reduction purpose. Any pointers/hints will be highly appreciated.
