The serial.c example code should work, but the serial tests in CYGPKG_IO_SERIAL will provide better verification of serial I/O. Make sure that you set CYGPRI_SER_TEST_SER_DEV appropriately and that you're running the ser_filter host tool at the other end of the serial link. If a particular test does not fit into RAM, you will see a linker error. You will then need to configure with CYG_HAL_STARTUP == "ROM" and write the test to Flash for execution on board reset. > Also, should I use EABI or will ELF do as well? It would be preferable to use the arm-eabi toolchain if only because it is likely to produce better optimised code than the older arm-elf toolchain. I hope this helps...
