Oe For Mot. E680/i Options

[rpconnect]

i'm interested in creating an OE build environment for the motorola e680/i linux smart phone and could use some advice.

both the qt-2.3.10 and opie-1.2.0 packages can be built (from scratch, see http://marcus.bluetroll.se/e680/) and run (somewhat) successfully on the phone using linux-ipaq-g++ as the platform specification, and i have tested binaries from h3600 opie_rootfs images (e.g ssh) and they work, so I am hoping that an ipaq machine/distro based build should be a good start.

The problem is the kernel version: the kernel on the phone (2.4.20) cannot be replaced w/o loosing the phones functionality, but the ipaq images (in bz2 format) that i can find seem to be for more recent kernels and a lot doesn't work.

The phone's kernel source is available from sf and ideally I'd like to create a build environment that is based on ipaq settings but builds with the specified kernel sources. Any advice would be most appreciated!

Feel free to join the OE team, read some of our getting started documents, and add some bits to OE to target the phone.

Hey, I though that the e680i was built using the MontaVista embedded environemnt, and pretty much locked out until Motorola decided to give developers permissions?

Otherwise, applications developed for the Zaurus would be a very close match with the e680i.

that is correct. however opie can be compiled against the same kernel as in the phone and, with the exception of some bugs (e.g. sound), it works fine, so i'd like to see this extended to as many packages as possible. i've also been able to get Xqt built to work on the phone based on the bitbake build process.

Some arm-compiled apps can be taken from some zaurus/ipaq feeds and will run on the phone, but not all. To make things completely compatable they have to be rebuilt w/ a soft-float enabled compiler. Additionally, the qt-libs cannot be replaced on the phone w/o loosing the phone functionality (the kernel sources are available at source forge, but the source for the phone apps is not available). To make opie (compiled against qt-2.3.10) and the native phone apps (based on qt-2.3.6, i think) the qt source has to be patched so that a proxy app can act as an intermediator (see http://www.rcsc.sisrs.com/mfc/index.php?na...iewtopic&t=1148 )

now that there is a tested cross-compiling toolchain and the kernel source is available i am trying to specify these as ASSUME_PROVIDED in the bitbake conf files, and apply the patches to the qt source, but i don't have either a lot of experience w/ this or time to work on it.....
