STM32N647Z0 failed to create the download file for mx25um51245 external flash

[liuqw]

I want to create an MX25UM51245G. sldr, but it keeps failing with a prompt

 

Use the official MX25UM51245G_STM32N6570-NUCLEO.stldr to confirm that the board can be downloaded successfully

 

Please check the MX configuration that I generated for MX25UM51245G_STM32N6_ ExtMemLoader. stldr

Trying to adjust to the overall size, but still receiving an error message

Hello ​@liuqw ,
Can you try setting the optimization to “Optimize for size (-Os)” when building the external loader.
