Hello everyone!
I am encountering an issue where USB_CoreReset hangs on both the STM32H7S3L8 and STM32H753ZI boards when configuring the USB_OTG_HS port.
I understand that this issue has been reported previously, and I have thoroughly reviewed most of the related posts over the past week. However, I have not found a solution that works for my case.
Configuration Details:
MacOS Sequoia 15.3.1 (Run IOC using: sudo /Applications/STM32CubeIDE.app/Contents/MacOS/STM32CubeIDE)
STM32CubeIDE Version: 1.17.0
STM32H7S3L8 Board
- USB_OTG_HS enabled in Device mode
- USB_HS_REGEN (USB Regulator) enabled
- USB OTG HS interrupt enabled
- Clock configuration:
- HSE = 24 MHz
- 60 MHz clock provided to USB_OTG_HS
- RCC settings:
- NVIC settings:
- Global interrupt for USB enabled
- USB_DEVICE enabled with Communication Device Class (CDC)
STM32H753ZI Board (NUCLEO-STM32H753ZI)
- Configuration is the same as above, except that USB Regulator not enabled (not an option in IOC)
Issue Description:
- When running in debug mode, the code gets stuck in CoreReset, which is called from USB_CoreInit.
- This behavior is consistent across both boards.
Things I Have Tried
Checking __HAL_RCC_SYSCFG_CLK_ENABLE(); in HAL_MspInit();
- STM32H753ZI: Already initialized.
- STM32H7S3L8: Not present; adding it results in "undefined" error.
Reinstalling STM32CubeIDE
Starting from a fresh workspace
Commenting out __HAL_RCC_USB2_OTG_FS_ULPI_CLK_ENABLE(); in USBD_conf.c
- STM32H7S3L8: This line does not exist in USBD_conf.c.
- STM32H753ZI: Commented it out, but it did not resolve the issue
Question:
What could be causing USB_CoreReset to hang, and what steps can I take to debug or resolve this issue?
I have attached my IOC files for both boards for reference (STM32H7S3L8 is USB_init and STM32H753ZI is USB_initialization) Any insights or suggestions would be greatly appreciated.
Thanks in advance for your help!
