I think you need to step off your soap box! Big endian isn't going away, and it likely has nothing to do with code bases. Just look at networking and telco protocols. Everything in that world tends to be big endian. BE is what is understood in that world, and there's little we can do to change it. Demanding that they switch to LE is tantamount to you demanding that their entire world change - it ain't going to happen. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line in suburbia: sync at 12.1Mbps down 622kbps up According to speedtest.net: 11.9Mbps down 500kbps up
