Anybody running NTP on a Shark with GPS/PPS?


How well does it work?  Any surprises or gotchas?

I'm using a partially homemade radio clock receiver (tuned to MSF on 
60khz in the UK) with PPS output, and a custom refclock/tty line 
discipline, on a Shark:

remote       refid      st t when poll reach   delay   offset  jitter
========================================================================
*LFCLOCK(0)  .MSF.       0 l   16   64  376    0.000    0.208   0.016
 LOCAL(0)    LOCAL(0)   11 l   10   64  377    0.000    0.000   0.000
...

It works a treat.

Cheers, Steve

trying to boot on ADI coyote

Hi all,

I'm tryning to launch a current on the ADI coyote board : 
http://www.adiengineering.com/productsCoyote.html

This board is quite similar to the IXDP425 board, so I tryed to boot an 
IXDP425 kernel : sys/arch/evbarm/conf/IXDP425

Redboot 1.92 is installed onboard, and succed in booting Linux (2.4 
kernel for coyote) :
    RedBoot> load -r -b 0x1600000 zImage
    Using default protocol (TFTP)
    Raw file loaded 0x01600000-0x016a9d57, assumed entry at 0x01600000
    RedBoot> exec
    Using base address 0x01600000 and length 0x000a9d58
    Uncompressing Linux................................................ 
done, booting the kernel.
    ...

The problem is that netbsd IXDP425 kernel is configured to be loaded at 
0x10200000 (KERNEL_BASE_phys = 0x10200000), and this address is invalid 
on coyote. So I rebuild netbsd t be loaded at a lower address : 
KERNEL_BASE_phys = 0x1200000
    RedBoot>  load -r -b 0x1000000 netbsd.bin
    Using default protocol (TFTP)
    Raw file loaded 0x01000000-0x012abbdb, assumed entry at 0x01000000
    RedBoot> exec 0x1200000
    Using base address 0x01000000 and length 0x002abbdc
    $T050f:01200070;0d:0000b2c0;#3e$T050f:01200070;0d:0000b2c0;#3e

The last time I saw that kind of output on an xscale board it was caused 
by using the wrong endian toolchain to build the kernel.

The IXP425 cpu runs in big-endian mode on the Coyote, so make sure you 
use "build.sh -m evbarm -a armeb" when building the cross-toolchain.

Just noticed something else...

That address *is* valid on the Coyote. At least, my Coyote reports the 
following on powerup:

	RAM: 0x10000000-0x12000000, 0x10115668-0x11fdd000 available

And, in fact, I use 0x10200000 here for KERNEL_BASE_PHYS on the board.

Thanks for your advice : I was not compiling in big endian. But the 
problem still remains : I suppose that my coyote or my redboot 
(preinstalled redboot 1.92) is different than yours.

See my redboot log :

Mine came with RedBoot 2.0. Which is odd, since the firmware date is 
earlier than yours:

	RedBoot(tm) bootstrap and debug environment [ROM]
	Non-certified release, version 2.00 - built 16:08:18, Apr  1 2003

	Platform: COYOTE (XScale)

It would seem you have a later revision of board; the IDE interface is 
supposedly not working on mine, though I've never tried to use it.

This is true. However, there is *always* an alias of SDRAM starting at 
0x10000000 (the ixp425 can have a maximum of 256MB SDRAM). So I suggest 
changing KERNEL_BASE_PHYS to 0x00200000.

NetBSD/arm on Intel XScale PXA255 based board


Hey all,

I'm willing to get several PXA255 based boards from CompuLab. Hardware
description is available at http://www.compulab.co.il/armcore.htm

Vendor officially supports only Linyx, VxWorks and Windows CE. And i want to
run NetBSD 1.6.1 or -current. Maybe some netbsd-arm guru could consult me a
bit how hard it will be to flash NetBSD on this board ? Just i'v never tried
NetBSD/arm port before.

Thanks.

current not booting on shark?

I know this comes up every now and then, and usually is (suposedly) caused
by bugs in the firmware making it impossible to boot from some parts of
the disk - I've seen that before and always was able to recover by copying
the kernel(s) again.

This time it is pretty persistent:

and I made sure the kernels end up early on the disk:
