Hello, code in u-boot/cpu/mpc8xx/fec.c for MII speed seems to be wrong in the case that busfreq != intfreq (I have 133MHz internally and 66MHz bus) current code: fecp->fec_mii_speed = ((bd->bi_busfreq + 4999999) / 5000000) << 1; correct: fecp->fec_mii_speed = ((bd->bi_intfreq + 4999999) / 5000000) << 1; Frank
