Hi Hans, Eric: I would be interested in getting any driver code examples for Bestcomm/PSC6/CODEC for the mpc5200 as well. I am developing a couple of drivers: one a Data Acquisition driver for SPI based AD7683 SAR ADC on PSC6/codec and a LCD user interface on PSC3/SPI using the DENX Linux distribution. Is arch/ppc/5xxx_io/i2s.c a good example of a Bestcomm, Codec, non Ethernet example? Thanks to you guys and Wolfgang for you contributions to this thread discussion. */Frank Bennett President /*Mathegraphics,LLC 613 Bentley Pl Fort Collins,CO 80526 www.mathegraphics.com bennett78@digis.net
