Good day.
We have faced with problem that USB1 on RT1051 does nit work.
All power supplies are well (USB CAP, USB VDD and other digital supplies).
USB even does not work in full speed (thus the trouble is not in DP/DM layout).
The MCU is stalling after command execution
static void USB_DeviceEhciSetDefaultState(usb_device_ehci_state_struct_t *ehciState){
...
hciState->registerBase->DEVICEADDR = 0U;
}
Also USB bootloader does not work.
What bug can cause all these problems?
Hello,
Please try to verify 24 MHz (XTALI/XTALO) oscillator frequency, which
inaccuracy \ stability is USB sensitive.
Have a great day,
Yuri

Good day.
We have verified it already.
We even soldered quartz 24 MHz from EVK.
No changes
