Yes, switching this on is a brute force attempt to bypass any bufferization and allow printk to call the console driver directly regardless of the current domain - this may, or may not work, depending on the level of brokenness of the current situation (this said, if I don't get why printascii() as used by my_printk() does not send the characters to the uart as expected). > Steven -- Philippe. _______________________________________________ Xenomai-core mailing list Xenomai-core@gna.org https://mail.gna.org/listinfo/xenomai-core
