The only ports I remember having (I don't have it in front of me right now) are Ethernet and CompactFlash. The Netstix is supposed to be using OpenEmbedded, and I think that's going to work better for what I'm trying to do. Will the section on reflashing u-boot at the bottom of http://www.gumstix.net/Software/view/Developer-how-to-s/Reflashing-using-a-Linux-login-session/111.html work for what I have now? If so, is this the process I should be going through: - Download the u-boot image from http://gumstix.net/feeds/u-boot/u-boot-connex-400-r1578.bin - Store the u-boot image at /tmp/uboot.bin - Follow the last section from http://www.gumstix.net/Software/view/Developer-how-to-s/Reflashing-using-a-Linux-login-session/111.html to reflash u-boot - Reboot - Follow the rest of the guide to update the kernel and root filesystem Is that going to work, or is there some other guide I should be following? -- Scott Lerman |
