Help with : External QSPI loader how to - QSPI driver - CubeMX

[TGate.1]

Hi all,

I have a custom board with STM32F767ZIT and an external QSPI flash MT25QL128ABA.

My QSPI mapping is :

• CLK : PB2
• CS : PB6
• IO0 : PF8
• IO1 : PF9
• IO2 : PF7
• IO3 : PF6

I made my own custom external loader for my QSPI with these ST tutorial :

• https://www.youtube.com/watch?v=alzv6qg4lH0&list=PLnMKNibPkDnHIrq5BICcFhLsmJFI_ytvE&index=3
• https://www.youtube.com/watch?v=XqCq0xtQmbI&list=PLnMKNibPkDnHIrq5BICcFhLsmJFI_ytvE&index=5

It seems worked perfectly, but I have an offset in my memory Flash.

I should have 0x00 at address 0x90000000 and not 0x01.

I have the same clock configuration.

I don't have the same QSPI memory so I made the modification below :

• I changed my QSPI configuration (FlashSize = 23)
• I changed the MEMORY_FLASH_SIZE from 0x4000000 to 0x1000000

I tried to modify the writing QSPI function in these example CSP_QSPI_WriteMemory but when I did it the last byte is not written in memory.

I just changed "sCommand.Address = current_addr" by "sCommand.Address = current_addr + 1"

Does anyone use this example to create external loader or has the same error ?

Thanks,

Tom,
