What's the best place to get that stuff? I picked up a copy of the sd8686 helper and firmware from the Marvell site (http://www.marvell.com/drivers/search.do) I specified Linux 2.6 Fedora as the OS and used SD-8686-LINUX26-SYSKT-9.70.3.p24-26409.P45-GPL I copied the helper and sd8686.bin to /lib/firmware (and renamed the helper to sd8686_helper.bin in the process) Didn't have much more success though :-( The error is slightly different now: mmc1: new SDIO card at address 0001 firmware: requesting sd8686_helper.bin libertas: failed to load helper firmware libertas_sdio: probe of mmc1:0001:1 failed with error -84 Before beating my head against the wall too much on this, I've requested a copy of the proper helper and firmware from wi2wi, since it is not at all clear to me that the ones from the Marvell site are the correct ones. > Do we know that this driver behaves with SDIO yet? I'm not aware of anyone else who has used the hsmmc driver with SDIO, so I think we are pioneering. Certainly the libertas_sdio driver itself has been proven on other hw. TI claims that the 1.0.2 release of the 35XX EVM software will support the libertas_sdio driver via the EVM's mmc slot. However, I don't see that version of the software yet on the TI site, and my guess is that it will be using the internal TI kernel and not linux-omap.
