[SOLVED] J-Flash + custom ext. flash downloader

I have a board that uses STM32F746 uC + S25FL128S QSPI ext. flash. I need to put data in it with J-FLash. As I understand it should be pretty straightforward when memory addresses are properly configured. I actually managed to make J-Flash start and finish the programming process. The problem is that it uses ST_STM32F746G_Disco_QSPI.elf as a flash loader and i have different pins for D0 - D3 signals, so naturally there is no data in the memory. So the option is to use Open Flashloader. However I would need to implement all functions by myself, where probably just reconfiguring these 4 pins would do. Is there anywhere I could find source code for ST_STM32F746G_Disco_QSPI or am I left with writing everything by myself with Open Flash loader Cortex-M Template?
