Is anybody currently > working on that? http://www.sun.com/microelectronics/table.html Contains online programming manuals for sun4m, sun4u processors which I find a good supplement to the SPARC Arch. Manuals. They document the MMU interface and extended ASIs, traps etc. I am using gcc-2.7.2.1 and binutils-2.8.1 with a bunch of cygnus patches configured as `sparc64-elf' as my toolchain. I just submitted a port for elftoaout (PR# ports/7150) to convert static sparc64-elf images to a.out format which can be netbooted by the Ultra's openboot prom. Right now, I am digging in the OpenBoot client-interface. I took the liberty of asking http://www.firmworks.com to donate Open Firmware documentation, but got no response. -- Kapil Chowksey Viva GNU ! kchowksey@hss.hns.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-sparc" in the body of the message
