How to program to external flash on custom board

Hi everybody!

I have problem with download hex file to memory.

My project uses STM32F769 and QSPI (MX25L51245G).

Here is pin map of QSPI:

QSPI_NCS <-----------------> PB6

QSPI_CLK <-----------------> PB2

QSPI_D0 <-----------------> PD11

QSPI_D1 <-----------------> PC10

QSPI_D2 <-----------------> PE2

QSPI_D2 <-----------------> PD13

This pin map of QSPI is different with pin map of QSPI on STM32F769 Discovery board.

When I use the ST Demo hex file to program to my custom board by ST link Utility, it shows message: ''time out during flash program''.

Here is image:

Could you please help me to solve this ?

Thank you very much.

It looks like no way to change ST-LINK pin configuration to QSPI Flash.

I suggest use external programmer to program your code.

Hi Minh Phan,

how did you solve your problem .........?

We too have made a custom board for stm32f7, and are facing the same issue.

The nor flash is not getting programmed using st-link.

If you have solved your problem, please let us know the solution.

Thanks and Best Regards,

You would need to craft a custom external loader to address the specifics of your board and part choices.
