How to compile and link a program to a specific .text address

I think the best bet is likely to override the linker script. You can either dump the built in one by doing:

qcc -Vgcc_ntoppcbe -o<bin> bin.c -Wl,--verbose=5

Then save the output of the linker script with the modified address you wish (I've attached an example).

Alternatively, it appears you might be able to create a smaller linker script that enhances the built in one using the INSERT rule to augment the overall linker script with the different base address.
