In theory BASEPRI should have been set to 0x10 by both bootloaders by the time the application starts running. That the Windows-built bootloader has not done that is unexpected. It looks like the actual bug is in the Windows build. The Linux build is doing what I would expect. So it looks like you have been fortunate not to trip over this issue earlier. The comparison of the executables that I mentioned earlier should help. It looks like only the bootloaders may need comparing. -- Nick Garnett eCos Kernel Architect eCosCentric Limited http://www.eCosCentric.com The eCos experts Barnwell House, Barnwell Drive, Cambridge, UK.
