Hi,

here an new interesting information, I checked the SCLK and SDI/SDO pins of the flash with the scope. While programming the flash and while booting from it I can see the clock and the data bits.

But when I call my_epcs = alt_flash_open_dev(EPCS_FLASH_CONTROLLER_NAME) there is NO activity one each pin. No clock no data.

Is there any new idea about this?
