The MMC core should be able to come up with the correct device. It
sounds strange that the driver would be activated for an SD card.

Could you provide some information on the board you are using. Type of
processor, kernel version, and anything else you can/want to share. In
/sys/bus/sdio/devices/ you may find the location of the bcm4329.

Current MMC stack in Linux would not confuse a MMC/SD card and a SDIO 
device. Basically the intialization and command sets they used are 
different.

Just for curiosity, do you know the version of your proprietary driver? 
You should be able to find it in epivers.h.

A crash log would be helpful to locate the issue.

So the crash is unrelated, is what you're saying?   I've attached the
log if that'll
give you some more clues.

Attached is a crash.log-file from the serial console.

Yes, it should have nothing to do with the crash.

This is weird.
#define  SDHCI_INT_ADMA_ERROR   0x02000000
Could you check why the the SDIO host controller is generating this kind 
of interrupt?

Also, comment out the line "brcmf_msg_level = BRCMF_ERROR_VAL;" in 
brcmf_c_init of dhd_common.c. Then insert fullmac module by
insmod brcmfmac.ko brcmf_msg_level=0x7. This will give you a more detail 
log of brcmfmac. But I am suspecting even the first SDIO read command 
failed.

"This bit is set if the Host Controller detects errors during
ADMA based data transfer. The state of the ADMA at an
error occurrence is saved in the ADMA Error Status
Register, In addition, the Host Controller generates this
Interrupt if it detects invalid descriptor data (Valid=0) at
the ST_FDS state. ADMA Error State in the ADMA Error
Status indicates that an error occurs in ST_FDS state.
The Host Driver may find that Valid bit is not set at the

Hmm, doing that, and loading this as a module instead of compiling it into the
kernel seemed to work.

Is there a reason for this not working when being compiled into the kernel? Is
it possible that I need to change the order of  some of the units
being initialized
in my machine-description / init?

I'm attaching the log from modprobe.

Regards,
Thomas

Ok, so I get the device listed as a wlan0-device, and I see the driver
being able to communicate
with the chip, sort of (it can read registers at least), but then I
start seeing errors like this (from
the previously attached log):

Usually we compile it as module instead of built-in. But I just tried it 
with built-in and it can intialize and scan. Some issue did happen 
during joining  an AP. So I would suggest use module for your 
development for now.

It's possible that the firmware carshed. Are you using the 
firmware/nvram from Linux repository? You should use the nvram that fits 
your platform.

I'm using the one from repository now, yes.

Using the firmware I had from before, the only difference I see is the
time of when
the IRQ handler is called, but that is probably just randomness, I guess?

Attached is the log when modprobing with old firmware.

I think both firmware is fine. I was referring to the 
brcm/bcm4329-fullmac-4.txt It's a nvram file contains critical 
information used by firmware. And it's hardware dependent. We have 
submitted a patch to remove the one in Linux firmware repository to 
avoid confusion as it's for a Broadcom internal development board. It 
may not work with your set up. I think there should be a similar file 
comes with the proprietary driver package if you are using a module 
instead of a 4329 chip. Please use that one.

The issue you facing is more likely SDIO bus connection issue.
brcmf_sdioh_request_word: Failed to write word, Err: 0xffffffac
mmc1: Got data interrupt 0x00200000 even though no data operation was in 
progress.
These may be both caused by data CRC error/time out.
I don't have Exynos 4210 spec. But I guess for a such new chip the SDIO 
host should be able to run the bus at 50MHz. You could try to hack the 
MMC/SDIO host driver and reduce the max frequency to 25MHz or even 
further to 12MHz to see if any improvement.

I did two tests one with only changing the nvram-file, and one with
changing both
the firmware and the nvram-file (this is the latest logfile you got).  Both had
the same result.

Max clock is 63MHz, and the setting we have now works with 2.6.36 and the
proprietary driver (bcm4329).

Looking at the platform-code we have for 2.6.x, I see that we set
.cd_type                = S3C_SDHCI_CD_GPIO,
Instead of
.cd_type                = S3C_SDHCI_CD_INTERNAL,

I don't know if this matters (looking at the schematics, the clk-pin is the same
for mmc2 as it is for the gpio).  Is this something related to the old
proprietary
driver?

Hello Thomas,

The max clock speed supported by 4329 is 50MHz.

According to the driver (mmc-driver, that is) it's running at 50MHz.

I'll try to see if I can lower it to 25MHz, if you think that could
solve any problems.

Yes please give it a try.

About the functional combination of .36 kernel + proprietary driver, is 
it a mainline kernel or an Android one?
