Andrew -
Thanks so much for your reply and candor - that's kind of what I needed to hear either way.
I'll check out the others you mentioned first, before trying to dive into changing PMON (we already have had to mod PMON, but only changing existing code/regs/etc.)

Hello -
We're using PMC's MSP8510 MIPS processor. Included in
the
BSP was Linux 2.6.18 and PMON2000. We have all running, except the boot from CF. I'm a bit familiar with
GRUB/LILO,
and I'm looking for a direct replacement, and we
thought
we'd be able to use either until we saw GRUB was not
ported
to MIPS.
However it looks lile U-Boot accomplishes both (PMON+GRUB-like functionality) since I see some
indication
U-Boot handles VFAT? (how about ATA CF?) (If U-Boot can read a VFAT CF, and load the linux image from there,
then
that negates the need for any subsequent boot loader
like
GRUB/LILO - right?)
Any recommendations out there? (such as "trash PMON
and
go with U-BOOT - it does all you want" or "look here
xxx to
find what you want")
I would guess it would be easier to add code to boot from ATA to pmon-2000 (never used the -2000 version, just the old pmon a ong time ago) than to do a new port to something not supported (u-boot for mips is not in the best of shape). That being said, we boot a Raza Au1550 MIPS using u-boot off of CF. I believe the s/w guys are using ext2 on the CF instead of vfat, but it does work.
You could also look at MIPS's yamon, Broadcom's CFE, or MicroMonitor (umon) as other bootloader choices.
