This makes things worse on mpc8272ads -- the result of the division is 13.56, but I only get error-free serial output when rounding down. I don't think the remote end has timing problems, as I don't see this with any other board. Possibly the crystal is a little off, or maybe it's just better to be a little too fast than a little too slow for some reason? Maybe we should change CPM_CLK to be MAIN_CLK/4 rather than MAIN_CLK/16 when the BRG clock is below a certain frequency. -Scott _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
