Card Services in a FADS850SAR board

Card Services in a FADS850SAR board

[Leonardo Pereira Santos]

	I know, I know, the FADS board is a piece of c**p but it is the only card I
will have for some time now I i stuck with it :( . Ok, I trying to make the
boad's PCMCIA connector work. I'm using a recent kernel (2.4.20-pre11) in a
MPC850 processor, and the PCMCIA card is a WiFi card.
	First I compiled the kernel with built-in PCMCIA support and modules for the
card's drivers. The first strange thing is that the PCMCIA interrupt
generates a sig 11 error (kernel accessed bad area). But if I boot
(initialize Card Services) with the board already connected, the 8xx module
works fine. So I load up the three driver modules I need (hermes, orinoco,
orinoco_cs), but when I do a lsmod, the orinoco_cs is listed as unused.
Shouldn't the cs driver be used by Card Services? In Paul J. Lucas' page
about a PCMCIA in a PowerBook there is a fine "dummies guide" to make it
work. I followed it but CS' cardmanager doesn't load up the drivers, although
it identifies my card. In Paul's page, he says CS versions prior to 3.1.27
don't work out-of-the-box with a powerpc, and the kernel's version is 3.1.22.
	So I went to CS' HP, downloaded and complied  it to my kernel. After starting
CS with a insmod, when I tried to load the socked driver to the 8xx powerpc
(m8xx_pcmcia) , it generates a sig 11 error in the middle of its
initialization. As a desperate measure, I trying to integrate CS' new code
(3.2.3) in the kernel, but that gives me a very strange compilation error in
re resource management code.
	After all this, my questions are:
	Should I tell my boss to give me a new board RIGHT NOW?
	If there is hope of making it work on my card, why the orinoco_cs module is
unused?
	I got the powerpc kernel in bitkeeper, there is another kernel with a more
recent version of CS?
	Am I making something really stupid compiling CS? I justo follow its
Configure script.
	Now the question that I fear: There is need of a ISA bus? If yes, where do I
configure it, as there isn't any option in the general setup menu in the
kernel config.
	I'm configuring my kernel to support:
	- hot plugable devies,
	- CardBus,
	- 8xx support
	The rest is the module support to my WiFi card.
	Sorry for the long mail. I'd be very grateful if anyoune could give me any
information. Thanks a lot!

Yes. And ask for a BDI2000, too.

The kernel we have in the CVS (2.4.4) plus ELDK 2.0 works find  on  a
couple of boards with PCMCIA cards, including WLAN (tested with DLink
and Elsa Airlancer [= orinoco]).

No.

Do _not_ include cardbus support.

Have you tried a non-kernel version of pcmcia-cs?
For the 850, you need to take care that PCMCIA_SLOT_B is defined,
instead of PCMCIA_SLOT_A.

ramdisk crash

[qi zhaoling]

hi ,
     I use the SELF from the denx corp to bring up my embedded linux.
 the PPCBoot and Kernel bootup sucessfully , but when i used initrd
 to mount ramdisk , the system crashed . but if i use NFS to mount =
 ramdisk
 , it's fine .

 i am sure:

 1. I build linux kernel according to SELF
 2. I build ramdisk according to SELF=20


 does anybody meet this problem also ? pls give me a hand .


 thanks
