Hi
    My working target is the arm926ejs based platform. we want to port the
gdb-stub to the u-boot. therefore two console port should be used, one is
for host teminal program , another is for the host gdb debugger. right now
the serial driver in our platform is polling based. Is there anybody kindly
telling me how to initialize the two consoles or any material I can refer to
and is it possible to achieve to port gdb-stub into the u-boot with such the
polling based serial driver.


Best Regards

Yin

Please check existing code before reinventing  the  wheel.  There  is
already  support  for kgdb in U-Boot, and there is BedBug, too. It is
probably more useful to adapt/extend one of those for your purposes.
