Perhaps you could explain ... are you running > the RTEMs tools under Wine?? The RTEMS "quickstart" example uses an .exe extension, so it looks like Yuke's toolset is braindamaged. <http://www.rtems.com/wiki/index.php/Quick_Start> Example: bash-3.1$ sparc-rtems4.9-gdb `find . -name ticker.exe` (bleah!) The RTEMS example is running on a simulator via gdb, which is a far cry from running on real hardware, booting either on bare metal (very big ouch) or using u-boot to start it (much less ouch - I would start by running your RTEMS build as a u-boot "application" - that gets you things like fairly painless serial support). Note to Yuke: this will be a learning experience for you - please keep us informed so we can learn vicariously with you. I'm not aware of anybody using u-boot to boot RTEMS, so you may have some useful stuff when you get to the end of your journey. We will help as much as we can... > Anyway, a good suggestion is to install ELDK and rebuild > U-Boot and update it, even get Linux booted. It may not be > your main goal, but consider it educational :) Note to Yuke: you should also have a JTAG debugger to recover from failed u-boot reprogramming if you rebuild and reflash u-boot. You may want to use a JTAG debugger even if you *don't* reflash u-boot. Note that the Abatron BDI3000 supports "gdb remote target". <http://www.abatron.ch/products/bdi-family/bdi3000.html> <http://www.abatron.ch/products/debugger-support/gnu-support.html> I think most of the competitors do too now, but I don't know. Definitely ask about their linux (as the host) and gdb (remote target over ethernet) support before you buy. USB-attached JTAG debuggers tend to be Windows-only. Bleah! On a positive note, I have a whole collection of single-board computers (curiously labeled "USB TAP" ;-) with a MPC866, usb, and JTAG interface. If only I had the time to port u-boot to them and make them useful... :-D > Cheers, > Dave Best regards, gvb _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
