A Geode based tablet with serial touchscreen and other niche items that will require me to build a custom kernel for proper support. Also worthy of mention is that syslinux is no longer supporting the hardware. Its not too far from an olpc but its more proprietary. Made by DT Research. WebDT366 GX1 is the model. > Okay, as far as I remember geode is x86 architecture. So at-least architecture is supported.

The docs seem to assume a level of knowledge that I do not have on open embedded or a work flow within. Laying down that many bsp commands with no knowledge of how to use is daunting. > Start with a known board and learn how to build the image and flash it and boot.

My hope is to make a .img that can be dd'd to the target with full hardware support. > Here as-well the RPI is a good source of information http://git.yoctoproject.org/cgit/cgit.cgi/meta-raspberrypi/tree/classes/sdcard_image-rpi.bbclass?h=fido > Thank you in advance > Daryl Regards, Christian > > -- > _______________________________________________ > yocto mailing list > yocto@yoctoproject.org > https://lists.yoctoproject.org/listinfo/yocto >
