inAccess Networks JTAG tools is a collection of code and a set of tools
for using the JTAG interface (present in most modern microprocessors)
to perform hardware tests, and for programming Flash Memory Devices
connected to the processor's bus. It is especially useful for performing
initial hardware tests and for bootstrapping prototype systems. It runs
on a "host system" (e.g., a desktop computer with Linux) and accesses
the "target system" (e.g., the embedded system's CPU board) through a
simple five-line hardware interface. The host system's parallel port
is used as the hardware interface, though other arrangements can be
supported very easily. It is quite modular and though it currently
supports the Intel StrongARM SA-1110, the Intel PXA255, and the Intel
StrataFlash ICs, it can be easily extended to support other target
hardware configurations by writing simple modules.
