. However, before invoking
nmake
(or
nmaker
), the user needs to be aware of the
following items:
Though PDREM supports a virtual UART interface that the application can use to
communicate with the Remote Console window of the Paradigm Debug/RT, the
target.h
file in the
pdrem
directory does not have the serial I/O interrupt vector set. To be able to
send the string from a printf() statement of a C program to the Remote Console window,
the user needs to change two lines of code in the
target.h
file as shown in Figure 4. The
information that needs to be changed is shown in boldface.

chip selects). However, there is a memory limitation on how many

initcode parameters can be used at address 0xf7ff0 (will run into
//
flash downloader). Since the flash downloader will jump to address
//
0xf7ff0, the initcode is used here to serve as a jump to pdremote's
//
code. The class, LOCATE, will contain the jump automatically.
