Executing samle RTEMS application on QEMU

[S Akhtar]

Thank you very much for the help.

I tried it for pc386 and it worked on qemu absolutely perfect!!
But my ultimate target is to run RTEMS on i386ex custom board.

To download it on board i have converted hello.exe in intel hex format
(hello.hex) via i386-rtems4.10-objcopy command, because hex format is i386ex
processor compatible.
But when i download it in flash ROM via programmer, It gives error like
"Checksum error!"

How to recitify this error

Thank you for your time

Regards,
