debugport [options] [<port>]
Display help.
Forcibly set the debugport in the kernel superpage. This allows to change the debugport to (eg) zero on variants that incorrectly disallow it because they were copied and pasted from the sample variant code. It also bypasses any variant initialisation that might normally happen when changing the debugport, so isn't entirely safe. Requires memoryaccess to be available.
The debug port to set. The meaning of the number is platform-specific, but as a general rule: -2 means debug prints disabled entirely; Zero through n means uarts zero through n (where n is platform dependant); 42 means JTAG debug output (if supported by baseport). [int]
Sets the debug port. If the port is not specified, displays the current setting.
