Crash on write to USBC_UOG2_PORTSC1

I'm porting MQX4.2 to the i.MX6SX. I'm trying to make the USB v2 stack working.

When executing the usb_ehci_init() function in ehci_host.c, the cortex-M4 crashes when it tries to

write 0x10001000 in the USBC_UOG2_PORTSC1 register(@0x42184384).


Any idea why the M4 crashes?
