: The device in my HP nw8240 notebook is a Texas Instruments 7621. This
: device is a multi-function PCI device with a CardBus, firewire, Flash
: Media and SD controller. The only way that I could get this driver to
: work for me is to disable SD card detection on the Flash Media
: controller, which is function 3 :
:
: pcitweak -w 02:06:03 -b 0x4c 0x02
I have patches to mav's sdhci driver to do this. However, I can't get
the driver to work. It detects the cards are inserted, but then all
commands that require a response from the card fail.
How many slots does your controller report? Which one is sd?
