Help with QSPI write function

Question asked by Jaime Rodriguez on Jul 22, 2009

I am following the QSPI example about the EEPROM and the M52259EVB, I have an oscilloscope plugged to QSPI_DIN, QSPI_SCK and QSPI_PCS0. I am debugging the example but when I execute the function       result = write(fd, send_buffer, len);    clock pin and DOUT pin never moves.


What could be the problem if I am executing from example provided from freescale?

Does anyone have had the same problem?

Does anyone have an simple and concrete example of writing and reading from QSPI?
