Another booting E3 here
by M P 02 Mar '06

02 Mar '06

My V4 E3 boots using Mark's tools. There were a few issues when building : + The buildroot "snapshots" fails to build, you need to explicitely tell it not to use snapshots of uLibc and busybox. After than you still will get a hanging boot until you fix the inittab + u-boot "examples" fails to build here, and break the build; I commented them from the Makefile and had to make clean && make to get a working u-boot.bin + The kernel config & patch as provided in the "v1" file works, however the delta-20060227.diff generates a kernel that hangs just after decompression here, no way to make it work... Looking forward to get that LCD + Console working :D Would it be easy to get the rootfs, u-boot and kernel in the flash ? we are fairly close to have a system that could be used to test stuff from a nfs partition or a usb flash drive; it would save a lot of time...

FB driver update + sound?!
by Mark Underwood 02 Mar '06

02 Mar '06

Just to let you all know that I am still working on the FB driver :). I have the LCD lit up in a nice all over turquoise colour but no Penguin and nothing I do seems to change that :(. The LCD registers have almost the same settings (one of the unused bits is set in my driver which wasn't set in the 2.4 kernel, but I can't see in the code where it could be set). I get 3 interrupts from the FB which looks about right as once it is up and running it's frame interrupt is disabled. The other news is that I have built all the sound stuff ok and I think it is working as the DMA interrupts go up, but all I have done so far is to 'cat /dev/urandom > /dev/dsp' which makes some difference to the noise, but as the unit is always generating noise I don't know if it is playing my noise or its normal noise! I will hopefully have time to test it with mpeg321 tonight. If it doesn't work then I guess there is a bit in the latch that I need to set to switch on the output amp.

That's normal - we just changed it in later versions to be "less noisy" Cliff -----Original Message----- From: M P [mailto:buserror@gmail.com] Sent: 02 March 2006 10:57 To: e3-hacking(a)earth.li Subject: [E3-hacking] New E3, no linux boot messages ?

LCD is a go.
by Jonathan McDowell 01 Mar '06

01 Mar '06

http://www.earth.li/~noodles/images/e3-lcd.jpg I now have a working LCD on the E3. I'll try to get an updated patch out shortly; ideally once I've got the input driver hooked up as well to allow it to be used as a console.
