a new device. That said, we also use it extensively as a terminal emulator during development and have added a number of extensions for that purpose.

The current release supports the PXA250, PXA255, PXA270, and SA1100 (lart untested). It checks the IDCODE register and uses the appropriate BSDL structure.

6.2.1Requirements

The jtag executable runs either under Linux or Cygwin.

Under Linux, there are no known dependencies except for libc and lib- stdc++.

Under Cygwin, the jtag executable requires the ioperm driver to be in- stalled. This driver makes the ioperm() and iopl() system calls available under Windows for access to the serial and parallel ports. Note that after the cygwin package is installed, you still need to enable the driver through the use of the ioperm executable

For the cmd.exe inclined:

c:\> c:\cygwin\bin\ioperm.exe -v -i

or for the bash-inclined:

user@machine ~/u-boot-1.1.2 $ /bin/ioperm.exe -iv

Either way, the output should be something like the following.

Installing ioperm.sys...

OpenSCManager ok

CreateService ok

OpenService ok

StartService ok ioperm.sys is already running.

6.2.2Startup Options

jtag -t Generate a square wave on the processor pins.

This option allows pins to be checked in a sequence defined by the hardware file. A ’+’ or ’-’ keypress will scroll forward or backward through the list. Also, pin name can be entered directly. Entering GP0 will generate a square wave on GP0. A ’ ?’ will list matching pin names. Entering GP? will list all gpio pins.
