[ECOS] Re: Reboot/Familiar - HOW??

[Craig Vanderborgh <craigv at voxware dot com>]

Gary, thanks a lot for your response.  I'm glad to oblige.  Here are some
relevant details.  First, my iPAQ is an H3760, running a downloaded Redboot
binary.  My flash image store looks as follows:

RedBoot> fis list
Name              FLASH addr  Mem addr    Length      Entry point
(reserved)        0x50000000  0x50000000  0x00040000  0x00000000
RedBoot           0x50040000  0x00100000  0x00040000  0x00000000
RedBoot config    0x51F80000  0x51F80000  0x00040000  0x00000000
FIS directory     0x51FC0000  0x51FC0000  0x00040000  0x00000000
jffs2             0x50100000  0x50100000  0x00DC0000  0x00000000
zimage            0x50080000  0x00100000  0x000C0000  0x00000000

where "jffs2" is the contents of task-bootstrap-2.4.18-rmk3-hh8.jffs2,
and "zimage" is the kernel image zImage-rmk3, extracted from the
tarball.  I attempt to boot the kernel with:

RedBoot> ex -b 0x100000 -l 0x280000 -c "noinitrd root=/dev/mtdblock/3 init=/linuxrc console=ttySA0,38400" -w 5

and I see the following results:
