Subject: hard wired wifi chip on sdio
Date: Sat, 30 Apr 2011 17:42:40 +0200 [thread overview]
Message-ID: <4DBC2DF0.30101@vili.pmmf.hu> (raw)
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 hard wired on sdio bus, not plugged in. 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.
When I try to load wifi module, it failed, cannot download helper binary
to chip.
I tried to see the sdio bus with an oscilloscope to test it and I need a
lot of modprobe/rmmod sequence and I wonder, after the n-th sequence it
could works well.
It confirms my opinion, there should be an initialization problem,
because this card is a wired, not a pluggable card.
What is the correct method to force insert card event?
