       Hello,there is some question puzzled me.can rtems debug like Vxworks----just use network,in target run a daemon,i can download my app(such as ,helloworld) anytime i like  ? 
       as we know,under tornado(for example,for pc386), i just need build a boot disk(floppy) and a vxworks kernel,using the disk  boot my 386pc and the use network download the vxworks kernel.then i can download and debug my helloworld!
       can i develop my program for rtems just like that?
      if yes,how can i get my rtems kernel which have debugger server daemon and allow me download and debug my app(such as ,helloworld) anytime i like? i can use grub to boot my 386pc and download the kernel!
