STM32F7, Hard fault in USBH_MSC_GetLUNInfo()

Hosung · ‎2025-04-28

Hi,

I have a STM32F7 and I use USB MSC without RTOS.

When debugging with JTAG after connecting the USB memory, a hard fault occurs as follows.

*Check Appli_state = APPLICATION_START in USBH_UserProcess() before f_mount()

HAL version(MCU package): 1.17.2

FATFS version: R0.12C

What am I missing or could I do more of?

Hi @Hosung

Could you provide a minimal project setup to reproduce the issue on a reference board, such as the F767 Nucleo, for example?
