Dear sir/mam,
 
 
We are currently working on generating interrupts for USB functionality. As per the Reference Manual RM0457: STM32MP2325xx Advanced ARM-Based 32/64-bit MPUs, it is specified that the GIC interrupt number for USB_EHCI is 171.
However, we are encountering an issue where the interrupt remains continuously active without being cleared after writing 171 to the relevant registers. Interestingly, when writing any interrupt number other than 171, the interrupt is cleared as expected.
 
 
Best Regards,
