[MinnowBoard] using DLP-USB1232H, verification error. is it due to DP_IO3L in SPI header not connected ?

[Sathish Kumar Balasubramaniam -ERS, HCL Tech]

John,

Though I am giving 1.8v to SPI flash header, the CS, SCLK, MISO and MOSI comes from DLP-USB1232H which may be using 3.3v ??? not sure
May be this is the problem ?
If so, how can I turn these 3.3v to 1.8v in DLP-USB1232H ?


Regards,
B.Sathish Kumar

Are your logic pins running at 1.8V, or just feeding 1.8v into pin 1?
