STM32F750 QSPI Boot Issue

[arun singh]

I am trying to boot from the QSPI on F7508-DK board.

I followed the guide by ST mentioned at STM32Cube\Repository\STM32Cube_FW_F7_V1.16.1\Projects\STM32F7508-DISCO\Templates\ExtMem_Boot

Basically this needs to be flashed once, so the code can jump from 0x08000000 to 0x90000000.

It is working alright for the examples provided by ST, but when I write my own code, the system clock fails to initialize.

If I comment out the system clock config, even memcopy function is working well.

But again, without the system clock, Other things aren't working.

Hello @arun singh​,

Please provide more details to help you solve your issue.

You can share your source code with clock configuration to check more this behavior.

We would mind having a look at the configuration

@Imen DAHMEN​ Thanks for the reply, but I got it working. I forgot to relocate the vector table.

If anyone face this issue, you need to relocate the Vector table in the SystemInit function

SCB->VTOR = QSPI_BASE;
