About USB interrupt in i.MX6SDL.

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?

Best Regards,

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
