Could you provide the section number and the version of TRM you are referring to. > > Without the fix the driver causes extra clocks to be clocked to the > bus after DMA RX operations. This can cause interesting behaviour with > some devices. Could you provide more details on the errors seen i.e is the transfer aborted Thanks Hemanth ------------------------------------------------------------------------------ Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects _______________________________________________ spi-devel-general mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/spi-devel-general
