Oh and ... make sure you power the gumstix back up once your terminal is ready ^_^ -----Original Message----- From: gum...@li...

You have to have a serial console connection to a tweener to hit Uboot, power down the gumstix and have the terminal ready, and make sure you hit a key before the boot timer runs out... -----Original Message----- From: gum...@li... [mailto:gum...@li...] On Behalf Of Sean Wheeler Sent: Monday, July 24, 2006 5:17 PM To: gum...@li... Subject: [Gumstix-users] uboot? I had a question about uboot and when it's supposed to actually be going. When I access the gumstix via hyperterminal I am immediately prompted with the login and password. Isn't uboot supposed to run just before this phase? I've come to the point where I'd like to replace the file-system image, but I'm not sure how. The wiki says just "use uboot" and then goes on to describe things that are not similar to what I experience. Maybe I should elaborate on what I've got going on... there could be some other problem here. My setup is kinda convoluted so bear with me. It's just the way it is here. I'm doing all my coding on a linux machine (Ubuntu 6.06). The bluetooth dongle I have doesn't seem to be supported by this platform (it's a linksys usb adapter type) so I've been emailing myself any code I want to test and then sending the files via hyperterminal on a Windows machine. I'd use the serial port on the tweener, but, as a few of you may recall, it's mysteriously hosed. I discoverd, after receiving segmentation fault errors from ./<cbinary> on the gumstix, that I, in fact, have r 773. Instead of rebuilding the file system (as it mentions on the wiki) I opted for the more beginner approach (checkout and make the older version). I enabled c++ via the top level makefile in buildroot on my linux machine before making. I am able to use arm-linux-gcc and arm-linux-g++ to compile the .c and .cpp files respectively. When I transfer them over to the gumstix and ./ them, the .c versions work fine... .cpp not so much. It says I need libstdcpp.so.6. I take this to mean that I need to re-image the file system on the gumstix so that it knows what to do with the cpp binaries since that's not enabled by default. I realize that my programs in C work just fine, but I want the option of coding in C++ if I should so desire. I think what I've done so far is correct, but, like I said, I dont' really follow the comments on the wiki about using uboot. If someone could help me out I'd appreciate it greatly. Thanks yet again. -Sean ------------------------------------------------------------------------- Take Surveys. Earn Cash.
