Hi,
Because the stock Glo kernel has no iptables support, I have compiled a custom kernel with this option from the original kernel :
https://github.com/kobolabs/Kobo-Rea....6.35.3.tar.gz
I managed to write it to the Glo's internal SD card using dd if=uImage of=/dev/mmcblk0 bs=512 seek=2048 and to get the device to boot. However, of course, the modules used by the device need to be upgraded. I managed to compile functional versions of the USB network interface modules in /drivers/ntx508/usb/gadget and even managed to compile a new /drivers/ntx508/wifi/dhd.ko using
https://github.com/kobolabs/Kobo-Rea...2-03112011.tgz
However, after all this, though the device is usable and I can connect to the device from USB (indicating that the relevant modules are operational), the WiFi is not working. I can perform:
Code:
busybox insmod /drivers/ntx508/wifi/dhd.ko
busybox insmod /drivers/ntx508/wifi/sdio_wifi_pwr.ko
and an eth0 interface shows up in /sbin/ifconfig -a. However, trying to run "/sbin/ifconfig eth0 up" fails with "ifconfig: SIOCSIFFLAGS: Operation not permitted" (though I'm root) and "wlarm_le -i eth0 up" fails with "wlarm_le: wl driver adapter not found". Interestingly, trying to "rmmod sdio_wifi_pwr" triggers an oops (that gets written to dmesg):
Code:

Has anyone gotten the WiFi to work with a custom kernel for the Kobo Glo? My prime suspect is this sdio_wifi_pwr that should probably be recompiled somehow, but I do not know where this file comes from and how to recompile it (Google isn't very helpful). Any ideas?
Thanks!
