i.mx28 SPI with ref_io.1 problem!!!

[grekot]

Welcome.
I have a problem with support for SPI in imx287. 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.
Has anyone met with this problem and how you solve it?

Hi,

May I ask how are you configuring the IO1FRAC[5:0] and DIV[8:0] bits in both cases? Do you see a change in the clock frequency when you switch from ref_xtal to ref_io1?

Best regards.

Jorge.
