Content-Type: text/plain; charset=us-ascii Sender: owner-linuxppc-embedded@lists.linuxppc.org List-Id: Hello, Is there anybody with a serial console uart driver for ppc systems without using interrupts ? Is is possible to use any driver in "polling mode" ? (drivers/char/serial.c or arch/8xx_io/uart.c) I try to bring up Linux on my custom ppc board (PPC750, 64M, uart 16550) and my (selfmade) interrupt controller will not work at this moment. But it would be nice to have debug messages on the serial console. (log_buf is okay but not really the thing I would like to have) Can I work with a "polling driver" -> bash input/output ? I hope that I must not understand the whole driver :-) (only set the uart I/O range, and set the quartz divider) bye Andreas EMail: ASchreckenberg@dspace.de -- Life's not fair.
