Dear Sir or Madam,
Hello.
I have a question about USB interrupt in i.MX6SDL.
BSP:jb4.2.2_1.1.0
Board: Custom board
My customer set USB InterruptEnableRegister to usbintr=0x00000000 ( = All interrpts are disable).
However, the interrupt of SRI(bit7) and FRI(bit3) in USB StatusRegister sometimes occurs.
Is there a part which makes these interrupts enable in BSP?

In which archive is your customer making the modification of the USBINTR register?
Hi jamebone,
>In which archive is your customer making the modification of the USBINTR register?
kernel_imx/src/drivers/usb/gadget/arcotg_udc_uq/arcotg_udc.c
My customer set the fsl_writel(0, &dr_regs->usbintr) of function dr_controller_stop.
Best Regards,
Keita
