Ahh, hang on, somebody misunderstood something. The PC87366 numbers it's gpio pins in octal: GPIO23 is bit 3 in the second group of GPIO pins. So what you call GPIO16 is what the chip calls GPIO20. Yours is decimal, the chip uses octal. >- If you start at pin 3, there are at least 6 or 7 useable > GPIO pins, followed by a ground pin right afterwards. 8 actually, GPIO20-27. >- I found more IO pins, plus the serial pins, further down the > connector, in the expected places but again with the GPIO number > assignment not exactly matching the 4801 manual. They are GPIO04/05 and GPIO12/13 in PC87366 numbering. (Søren has confused the issue a bit by coming up with his own NET4801 GPIO numbers that run from zero to eleven, disregard those). -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [EMAIL PROTECTED] | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
