I'm using Microchip SST26VF064B SPI Flash memory with an LPC1768 from LPC.
It works until I change the SPI clock frequency from 24MHz to 48MHz.
I'm using HIGH-SPEED READ command that should work up to 104MHz (the power supply is 3.3V).
For example I read 0x28 0x26 when they should be 0x51 0x4C.
0010 1000 0010 0110 -> 0x28 0x26 0101 0001 0100 1100 -> 0x51 0x4CThey appears shifted by one bit... except the MSBit of the second byte.
What do you think?
