ISEE manufactures very powerful System-on-Chip ARM OMAP3 based boards. They don't use the mainline kernel but instead have their own forked v2.3.37 kernel and their own first stage bootloader (igep-x-loader). ISEE code can be found here: http://git.isee.biz/ So a great project could be give complete support to this board on the mainline kernel. IGEPv2 is one of the boards that Linaro uses as a reference for OMAP3 to test their kernels and rootfs images. I own one of these boards an in my free time I hack both the kernel and the U-boot bootloader to properly support the IGEPv2, but there is a lot of work to do and I found everytime more hard to find free time to work on this. So if you want to join me on this project it would be great :-) Best regards, -- Javier Martínez Canillas (+34) 682 39 81 69 Barcelona, Spain _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
