more on dwc_otg.ko module

I built the module as per instructions from the earlier post, and edited the 'vermagic' number in the binary file with a hex editor. Hopefully it will still work. The link to the building instructions is here:

The critical part I was missing was to execute

make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- menuconfig

which gives you a group of config options that is different from those to be found just by typing 'make menuconfig'. With these options, select "System Type ---> Parrot drivers ---> PARROT6 USB driver (Synopsys)" . Then you can type

make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- modules

This will compile the modules, including the dwc_otg.ko module. Then you have to edit the 'vermagic' string as described in the link below:

Then you ftp the module over and try the insmod command to see if it inserts.

$ ftp -n 192.168.1.1 (with no port num specified)
ftp> put dwc_otg.ko
ftp> exit

$ telnet 192.168.1.1
# ls /data/video
# mv /data/video/dwc_otg.ko /home/default/dwc_otg.ko

check to make sure that the file is large enough because 'ftp 192.168.1.1 5551' puts files in the /update directory, BUT the files have no contents.

# cd /home/default
# insmod dwc_otg.ko
# lsmod
(listing of inserted module)
# rmmod dwc_otg

So, so far it seems to work. Now we need to test the usb cable itself.
