Crosscompiling NetBSD for Fonera not working with HEAD?

I got a old FON2100 from a friend and thought it would be fun to try  
runing NetBSD on it.
I searched and found this old thread: http://mail-index.netbsd.org/port-evbmips/2008/01/23/msg000012.html
So I looked at the Changelog, and HEAD seems to have gotten at least  
ath(4) and HAL updated in HEAD.
However, then I crosscompile the MERAKI kernel, it fails due to a  
missing file (from HAL i believe):

/usr/src/sys/arch/mips/atheros/ar5315.c:72:75: error: contrib/dev/ath/ 
ah_soc.h : No such file or directory
nbmkdep: compile failed.

More verbose output below.

Cool!  I've run NetBSD on the Meraki, but never on a Fonera.

It seems that the file has moved to
src/sys/external/isc/atheros_hal/dist/ah_soc.h.

I think that you need to change the #include line to #include
"ah_soc.h", and to make sure that the kernel configuration
includes sys/external/isc/atheros_hal/conf/files.ath_hal and
sys/external/isc/atheros_hal/conf/std.ath_hal in one way or another.
You can use the i386 kernel configuration as an example:

% grep external sys/arch/i386/conf/*
sys/arch/i386/conf/std.i386:include "external/isc/atheros_hal/conf/std.ath_hal"

% grep files.ath_hal sys/conf/*
sys/conf/files:include "external/isc/atheros_hal/conf/files.ath_hal"

Re: Crosscompiling NetBSD for Fonera not working with HEAD?

Hi,

This is due to the -Wl,--fatal-warnings flags passed to ld(1). This
seems to be a known issue:

share/mk/bsd.sys.mk:
 Set linker warnings to be fatal
# XXX no proper way to avoid "FOO is a patented algorithm" warnings
# XXX on linking static libs
.if (!defined(MKPIC) || ${MKPIC} != "no") && \
    (!defined(LDSTATIC) || ${LDSTATIC} != "-static")
LDFLAGS+=       -Wl,--fatal-warnings
.endif

I wonder why the logic didn't do its job...

Btw, if FOO is not defined, it will expand to "", doesn't it ? So what
is the point of the !defined() check ?

Re: Crosscompiling NetBSD for Fonera (mips) not working with HEAD?

Hello,

I had problems building release with "LDSTATIC=-static" on an older  
NetBSD machine, so I updated everything to current (HEAD) just to  
verify if those problems where fixed. But now I got problems building  
release due to librump:

Re: Crosscompiling NetBSD for Fonera not working with HEAD?

Hi David,

Yes, this fix the kernel build. This change need also to be made in a
couple or others files/headers (cf patch attached). I don't think any
of these files include `ah_soc.h' for HAL related purpose, cf the XXX
comment found in one of them:

#include <contrib/dev/ath/ah_soc.h>    /* XXX really doesn't belong in hal */

The HAL itself builds fine and is already included.

Yes, that did the trick.

While at the topic of Fon, I not sure which way is the best to flash  
it, and what forthcoming problems I might run into.
The most reasonable guide/up-to-date I found was the one for the  
MERAKI mini.

http://www.cuwin.net/manual/howto/meraki

I guess that this one would work with Fon as well (as you (David)  
mentioned earlier, they are very similar).

There is a comment in the end of this wiki article
(http://www.cuwin.net/manual/howto/meraki#comment-91 
) which mention questions about the root filesystem. I also thought  
about while analyzing the currently installed Fon image via the home- 
built serial cable. Openwrt uses JFFS2, but that doesn't seem to be  
supported by NetBSD (AFAIK). How did you do (with installing the  
userland) on the MERAKI mini?

Picking up this thread now that things calm down during the summer.

Well, I got the 5.99.11 kernel booting on one box now. Although there  
is still trouble with the ath0 wifi driver.
(Referring to this old thread: http://mail-index.netbsd.org/port-evbmips/2008/01/23/msg000011.html)

However, the HAL status is now Unknown instead of Atheros 2315 WiSoC.

can you please build a MERAKI kernel with:

That by itself didn't give any more information.

However, I looked around in the conf files and noted that in sys/ 
external/isc/atheros_hal/conf/std.ath_hal, these lines were commented  
out:

#options ATHHAL_AR5312
#options ATHHAL_AR2316
#options ATHHAL_AR2317

So I removed the comments, and now the kernel recognize the WiSoc  
2315, but crashes afterwards:
