hi everybody,happy new year.
I try to run TouchGFX project on STM32H750 Disco board
1.
in first level I run my project through QSPI,so i had frame lost and cant reach 60 frame per sec
2.
in second level i run my code from external sdram,i gain more performance but still i got lost frame
3.
in third level i run part of my code from internal flash and remained code from external flash,so there i got no frame lost.
but because there need for boot loader and other things to be placed in internal flash at later,so I have not space for my code(just i want test there execution code performance in third level )
4.
in level four I wanna to place touchGFX core in ITCMRAM as much as possible
(there is no enough space for all of touchgfx_core) but i got hard fault error
i attached excel file of compared items.
my project files is attached.
IAR 8.40.1 is my project IDE
my questions is :
1.why execute in place from QSPI is not like internal flash as ST company say?
2.can i move some part of TouchGFX core to ITCMRAM? how?what items should be concerned and what i should to do ?
3.do you have any or best idea for code execution place to got best performance ?
(need to concern i run it for 480*272 lcd but i need to run it for 480*800 pixel lcd at 30frame per sec at least.)
