Where can I download the Flash Loader sources from the STM32F7xx_QSPI.FLM (Keil uVision) to change the GPIO Pins? We want to integrate the Micron MT25QL512 Flash from the STM32F7x6_Eval Board into our circuit.

Should be patchable, state pin usage ​and clock specifics.

Hello and thanks for your fast anwering. But sorry I do not understand what do you mean with patchable. Is there a program to change the flash.flm file?

Modify the AXF/ELF file to use a different combination of pins. Wrote a program to do it for some of the ST loaders, being a guy who writes software.

Step One, is to understand the pins you're using and the clock sources the chip is run from.​

Hello, thanks again. I will try to go throug the .axf file and try to find the relevant entries.

Or you could just enumerate the pins you are using so I don't have to guess what they are.

Hello and a happy new year!

The pin enumeration:

NCS/PB6

CLK/PB2

IO0/PC9

IO1/PD12

IO2/PE2

IO3/PA1
