Yes. 10 seconds is required. 2 or 3 seconds is not enough to break in for automated QA testing. We are aiming for maximum reliability here. 2 or 3 seconds causes ~25% failure rate. 5 seconds causes ~10% failure rate. 10 seconds removes this element. (Estimates based on about a million LAVA test jobs across 50 different types of devices across multiple instances in multiple locations.) > -- > Tom -- Neil Williams ============= [email protected] http://www.linux.codehelp.co.uk/ _______________________________________________ U-Boot mailing list [email protected] https://lists.denx.de/listinfo/u-boot
