You could use a line like .set WANT_ISR_TX = 1 somewhere above the include "drivers/usartxxx" in your application file. >> Is it a warning that could prevent successful running on the >> target device? If you read the file core/drivers/usart_common.asm the line 28 looks as follows: .set XT_USART_INIT_TX = XT_NOOP The warning tells you, that the symbol XT_NOOP is not known to the assembler (yet). This will change in a later step during assembly thus the warning is basically a cosmetic thing. The definition of the WANT-Option as described above changes what the assembler will process in the core/drivers/usart_common.asm. The conditional assembly works just like the c preprocessor works, only the synatx is different. The details, including what the other words may change, I leave to you ;) Matthias -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEARECAAYFAlJW6c8ACgkQ9bEHdGEMFjOh0wCg9E3t4rYsvuAWgVPSsHgbp4s0 4L0AoIsFdAHmenP3Qt823rEpkedYviMO =L8bS -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
