I have an SPI code, which works fine with AT32UC3B0256 on EVK1101. I've built my own board with the AT32UC3B164, and the problem that I see is that MOSI stays high. The CS and CLK are present. The MOSI is showing some ripples when it supposed to send the data. I measured the resistance between VCC and MOSI and GND and MOSI on both boards, and it's the same, 100K. Is there something that I'm missing.
Thanks for all help.
