I have been hacking around with the 2.6.15 kernel and now have got the USB host to successfully register. It detects a USB device that I plug into it, but then fails to get the interrupt (the kernel prints out a time out error message). Looking at the proc enteries from the 2.4 kernel (from the website) the interrupt number is the same so I guess that there is some init code missing. Please could someone boot their E3, plug & unplug a USB device and do 'cat /proc/interrupts' and confirm that the usb-ohci interrupt has seen some interrupts.
Many thanks,
Mark

# cat /proc/interrupts 14: 0 OMAP1510 GPIO IRQ demux 25: 0 console/lcddma 30: 47416923 timer 31: 0 console/lcd 38: 47 usb-ohci 46: 2820 serial 57: 0 omap-rtc 58: 0 omap-rtc alarm Err: 0
That's just from inserting a USB device - my E3 is far away from where I am at present so I can't try disconnecting it too.

This is fantastic news Mark, and well done guys to getting as far as you have so soon. Is there any hope of the modified code being uploaded this weekend still? I would love to get my hands on it and start hacking away at a level I can understand :) To my mind the most useful part will be getting the networking stack fully functional to be able to mount NFS shares and try out different combinations of programs code and drivers. Really fantastic progress guys. Let hope it is just the tip of the iceberg as it were :)
Cheers,
Don.

Hi Don,
Hopefully it will be uploaded by the end of today. I have created a v1 release which has got a kernel that boots and working USB, although not NFS mounts as the shell is somewhat broken :-(. The next step for me is to get the LCD up and running and then sound (I would like my E3 to play my MP3's while I work on it :-). After that I guess I will either try to fix the shell problem or try to build microwindows/nano-X.

Hey Mark,
It's a small world isn't it! So, what have you actually got the E3 to do yet?

Hi Adam,
Good to hear from you. Have you got an E3?
I have got a (slightly broken) shell and working USB so you can work on a driver, put it onto the USB stick, mount the USB stick, and insmod it (thus saving you the 3 1/2 minute wait when uplading the kernel + u-boot + rootfs). You should also be able to compile simple programs for the E3 and run them, but with any sound or display your a bit limited, but I'm working on that ;-).

Excellent! I can confirm that it works a treat for me. Thanks for the hard work Mark. Now to go compile a driver for my USB ethernet adapter. :-)

Not as yet... I'm sneakly sat here watching how the development goes ;)
I'm playing around with a PC104 board at the mo with an Xscale 255 processor on it. It runs linux very well but I've got a long way to go :(
