    Jaya Kumar
    Hi, I would appreciate any feedback TI or others may have to offer on this issue. I've started comparing the working case (2.6.39) versus the failing case (2.6.37). The wl12xx driver in 2.6.37 is of course older than the 2.6.39 code and there appear to be some key differences. I stuck...

    Thanks for all the help folks. ;-) I finally figured it out. TI's Devkit 2.1 Gingerbread uses the 2.6.37 kernel but it doesn't actually use the wl12xx drivers that came with 2.6.37. Instead, it relies on some external detritus which isn't actually in their kernel tree. If you pull down their...

    Hi folks, I have a board with a WL1271 on MMC3 where I'm seeing a timeout in response to send_io_op_cond on 2.6.37. Exact same board setup works fine with 2.6.39. Pin-mux settings are the same (in fact, I'm using same mlo, u-boot binary when comparing the .37 with .39). My guess there is some...
