I've built a custom kernel based on Linux 2.6.37-rc8 for my Guruplug standard and all looks to be good apart from the wireless driver,
During the kernel boot process I get the following message:
libertas: failed to load firmware
libertas_sdio: probe of mmc0:0001:1 failed with error -5
I have copied the sd8688.bin, and sd8688_helper.bin to the /lib/firmware. A file named sd_helper.bin is also there.
What does error -5 mean?
