STM32F7 External Flash loader using QuadSPI

Hi,  I am developing a GUI based project using Waveshare Open7xxi board. The board consists of a stm32f746 controller. Since this is a GUI project I am saving all the graphic content in external Quadspi flash. Previously I have used STM32f746 discovery board, which has micron quadspi flash. To load the code into quadspi at the time of flashing the code, ST has provided driver(.stldr) file.   

Since I'm using W25Q128 qspi flash, I don't have external driver file for that. I have tried creating the (Flash load algorithm)FLM file using Keil, but when I saw it at logic analyzer, I wasn't able to see the clock.   

Since there is no source code available for STM32F7 external quadspi flash, I'm facing a hard time to write the flash load algorithm. Can anyone tell me what should I do to approach this problem? Does anyone have the source code for STM32F7 external flash which is using Quadspi?

Did you solved yours? How did you? I can not use that file you pointed out?

Thanks to all. The problem is resolved. The chip is defective.
