On the 68LC040 software FPU emulation errata...
Posted by: yuhong on 2010-03-27 17:04:06 For those who wonder when Motorola started producing 68LC040 processors without the errata that caused problems with software FPU emulation, here is the actual PCN right from Freescale: http://cache.freescale.com/files/shared/doc/pcn/PCNR00274.html
Posted by: johnklos on 2010-03-29 15:44:20 Cool - thank you. It's good to have a link like that which people can find easily. I'd also like to remind people here that NetBSD for m68040s with no FPU (no matter which mask) compiled with -msoft-float is available here: ftp://ftp.mac68k.org/pub/NetBSD/5.0.2/mac68k-softfloat/ and binary pkgsrc packages, also compiled with -msoft-float, are available here: ftp://ftp.mac68k.org/pub/pkgsrc/packages/NetBSD/m68k-softfloat/ The binary packages are being built on a 40 MHz Quadra 605 and are updated daily, so the list will continuously grow. Currently we're up to 238.
