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:


error message


Could you please help me to solve this ?

Thank you very much.
