Hi Andrew,

Thanks for responding. I added it to my template:

target cartesio {
         alias { "Cartesio (ARM) board" cartesio }
         packages { CYGPKG_HAL_ARM
                    CYGPKG_HAL_ARM_ARM9
                    CYGPKG_HAL_ARM_ARM9_CARTESIO
                    CYGPKG_IO_SERIAL_ARM_CARTESIO
         }
         description "
         The Cartesio HAL package provides the support needed to run
         RedBoot on the ARM processor of the Cartesio.

}

package CYGPKG_IO_SERIAL_ARM_CARTESIO {
     alias             { "Cartesio evaluation board"
                         devs_serial_arm_cartesio cartesio_serial_driver }
     hardware
     directory         devs/serial/arm/cartesio
     script            ser_arm_cartesio.cdl
     description       "Cartesio evaluation board serial drivers."
}

I added the code to packages/devs/serial/arm/cartesio/ - basically 
copied the AT91 code and modified it for my board.

When I rebuild, the serial driver doesn't get compiled. The 
build/io/serial/ does get compiled. I'm sure I'm missing something 
basic, but I can't figure out what it is.

Thanks,
Paul
