Andrew in Apps, I have downloaded the attachment, thank you. Unfortunately, I will be able to test it in two weeks. I have succedded in I2C-booting. Now I have flashed the same code to M25P64, switched proper BOOT Port (FPGA says: BOOT SPI). Turned free mode, but the leds are not blinking.. I wonder if there is something to do with SPI CS signal. GPIO20/GPIO24...
