freescale mx25 + libertas + 8688

Fri Apr 29 15:17:11 EDT 2011

Hi All,

I have a Freescale iMX25 based (tx25) board with a Marvell 8688 wireless 
module on sdio bus.
My kernel is a rel_imx_2.6.35_11.03.00 from freescale git repository.

The wireless chip is wired on sdio bus, not plugged. On end of 
sdhci_probe_slot() function I call the tasklet_schedule(&host->card_tasklet)
to force detecting card.

It seems to be good, mmc0 detected well.

After it, I would like to load libertas module:

modprobe libertas libertas_debug=0xffffffff
modprobe libertas_sdio

It seems to be, it couldn't loads helper firmware.
It can detect the card well:

[   61.639113] libertas sdio: class = 0x0, vendor = 0x2DF, device = 
0x9104, model = 0x10, ioport = 0x10000
but the firmware download returns -2.

the wanted firmware name is sd8688_helper.bin, which is in 
/lib/firmware/libertas directory.

What should be the mistake?

here is the complete log:
