O2 Joggler Forum

It won't boot Linux, strangely. I don't know if grub needs to see the internal partitions t correctly identify the USB stick partitions. I should probably look in the grub config file to see if that's the case. It just sits on the logo screen again. It does boot XP, however. This is where I identif...

using the new efi now. thanks for the heads up and your useful blog. know a way of getting usb keyboard support in grub from a usb booted disk ?I read before on http://jogglerhacks.blogspot.co.uk/2010/04/dual-boot-on-joggler.html "This way, Refit is added to the internal (nvram) bootloader lis...

I'd be interested to find out more about extending the 'extensible firmware interface' boot manager to utilize it's pxe boot capabillity so I can attempt to boot the Joggler off an LTSP server..not got too far yet due to the vagiaries of EFI, so if you can point me to any useful (read: usable!) inf...

Is there some description somewhere in more detail? I assume the devices still boot from USB: can you tell whether they are booting via startup.nsh or boot.nsh? Normally the joggler will not read a startup.nsh from a USB stick (as it searches the eMMC first), so knowing which script it's executing w...

I am here already, I just haven't posted much. There's not a lot of end-user useful stuff to report yet; the blog is for people who like reading about stuff being developed. :) I'm using rEFIt temporarily because it gives me easy access to the EFI shell and choosing what bootloader to start, but it'...

Found it: recent kernels are by default built to run from a 16MB aligned address, whereas all the joggler kernels that work are aligned to 1MB. This appears to be grub's fault for loading it in the wrong place and then the kernel relocating itself to somewhere that overwrites EFI services. To work a...

Already tried with the other video drivers disabled, doesn't help. Grub prints the usual output then everything just stops. I'm currently building a series of kernels based on the working ubuntu config, but successively changing options to match the debian defaults. So far it's still working, so not...

It's the standard Debian i386 3.1.8 kernel from unstable; here's a copy: http://whitefang.wolfpuppy.org.uk/temp/debian-config Thousands of options are different, but there's nothing that's obviously suspect. I don't care about the patches currently since they aren't required to boot; I'll work on ge...

I'm attempting to get the standard Debian kernel to support the joggler, in order that you can run debian-installer on-device and generally use it without a custom kernel package. If I use the debian sources with the config from http://joggler.exotica.org.uk/ubuntu/ the kernel works, but the standar...

Yes, but from where? With what changes?

Where does this build of the refit binary come from? Are there patches/special config needed to get it to work on the Joggler? The standard refit binary download doesn't load, the EFI shell says it's not a valid binary.

Yeah, after more experimenting it appears to work okay once you leave it in the O2 OS for a while and the device is a bit warmer. I can live with that

Thanks for the info, folks.

Hi, I just got a joggler, and whenever it's powered on the screen is corrupted. The corruption persists (varying in form, but mostly ugly scanlines obscuring various parts of the display) until I boot something that actually initialises the display for graphics; the EFI bootloader, grub, and any tex...
