If the clock source settings "ref_xtal", everything works perfectly. But when the clock signal as a source of law "ref_io.1", while reading the last bit is erroneous, in random bytes.</SPAN><BR /><SPAN style="font-size: 15px; font-family: Arial; color: #000000; background-color: transparent; font-weight: normal; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline;">Has anyone met with this problem and how you solve it?</SPAN></P></BODY></HTML> Mon, 04 Jun 2012 05:22:23 GMT https://community.nxp.com/t5/i-MX-Processors/i-mx28-SPI-with-ref-io-1-problem/m-p/165789#M4415 grekot 2012-06-04T05:22:23Z Re: i.mx28 SPI with ref_io.1 problem!!! https://community.nxp.com/t5/i-MX-Processors/i-mx28-SPI-with-ref-io-1-problem/m-p/165790#M4416 <HTML><HEAD></HEAD><BODY><P>Hi,</P><P>&nbsp;</P><P>May I ask how are you configuring the IO1FRAC[5:0] and DIV[8:0] bits in both cases?
