Hi, I'm trying to boot UltraZed-EG SOM from QSPI Flash on our PCB board. I refered to "UltraZed-EG Starter Kit Tutorial Version1.0". It seems that "Program Flash" command works well. I set UltraZed-EG SOM SW2 Boot Mode switch to 0x1(QSPI Mode). Then power-on our PCB board but it is not working. We have checked that UltraZed-EG SOM is power on, and we are assuming that FPGA loaded propery. We tryed out 2 designs. The one is our product design and the other is UltraZed-EG Starter Kit Tutorial that is provided at here: http://zedboard.org/support/design/14201/126 . Both designs are well-worked with the IO Carrier Card and with JTAG debugging on our PCB board. What may be causing this problem?
