ZYNQ XA7Z030 QSPI Boot With 100 MHz Clock

Hello,

 

I work on XA7Z030 custom board. It has N25Q256A flash. I need to write/read this flash with 100 MHz clock. I decided to boot with 100 MHz clock. Firstly, I changed fsbl source code. (In qspi.c, XQspiPs_SetClkPrescaler(QspiInstancePtr, XQSPIPS_CLK_PRESCALE_4);) The FPGA boot successfully with 50 MHz clock. When I changed prescalar value to 2 (In qspi.c, XQspiPs_SetClkPrescaler(QspiInstancePtr, XQSPIPS_CLK_PRESCALE_2);) It did not boot. I also defined FSBL_DEBUG but there is no debug output on the console.

Vivado version:2016.2

How can I solve this problem?

 

Thanks,

Muhammet
