any news about issues with the bootloader after android 2.2 was installed ?

Asked by Thomas on 2011-03-11

Hi,

I tried to install ubuntu with the modified bootloader. I've done everthing, but the new bootloader doesn't want to boot from SD or USB. My Ac100 has already the Update to Android 2.2 installed, and I read about some issues with that here in this list. Are there already any known solutions or workarounds for this ?

Thanks,

Thomas.

currently there is no known method to boot the .29 kernel with the new bootloader. this situation may change when the .32 sources have arrived (next week or so).

Hi Marvin,

thanks for your answer. One general question:

Why do you guys change the kernel-image ? Isn't it possible to change the bootloader ? Even to achieve the possiblitiy of the recovery mechanism ?

Regards,

Thomas.

the bootloader is closed source (proprietary) so we cannot change it. kernel is open-source. a new bootloader is also in the works, so we'll get dual-boot (better multi-boot) back sooner or later.

btw, it would be more convenient for us if you would use our irc channel #ac100 on freenode.net to ask questions (if you have more).

 Hi to all.

 are you sure the new bootloader checks only the kernel subversion
instead something more specific like a hash code?

the bootloader doesn't check what kind of thing it boots (otherwise a modified kernel wouldn't boot at all). it's more a issue with either the (machine id <- that's my guess) or how the bootloader sets up the hw (.29 may expect something different). on the other hand, the .36 kernel boots fine (with modified machine id).

Can you help with this problem?
