Re: Bootstrapping gumstix?

[KIYOHARA Takashi <kiyohara%kk.iij4u.or.jp@localhost>]

Hi! John,


First of all, what do you have gumstix?  current source code supports
to basix and connex.  If you have verdex or verdex-pro then require this
patchs.

  ftp://ftp.netbsd.org/pub/NetBSD/misc/kiyohara/gumstix/

  more latest patch is '*-20090221.diff'.
  It tested current source tree at 20090221.

The U-boot loads u-boot-image at a2000000, and parses header of image, and
copy to load-address(0xa0008000).
In case NetBSD, U-boot loads the striped kernel(netbsd.bin) at 0xa0200000
directly.  If you create u-boot-image then can load to a2000000 or
approximately.

You can put sys/arch/evbarm/compile/u-boot-mkimg.sh.

  ftp://ftp.netbsd.org/pub/NetBSD/misc/kiyohara/tmp/u-boot-mkimg.sh-20080821

Also edit sys/arch/evbarm/conf/mk.gumstix.

You can use netbsd.old.bin, if version of u-boot 1.1.4 and older.  Or
netbsd.img.

If your board is basix then add 'busheader=basix'.  Or 'netCF', 'netDUO',
'netwifimicrosd' or others.
