Hi Wolfgang,

Have you tested USB host functionality on a mx53loco with a Freescale MC34708 PMIC ?

I can succesfully detect a USB pen drive on a mx53loco board with a Dialog PMIC, but not on the FSL PMIC version.

I am going to debug this, but just wondering if you have already seen this issue.

Thanks,

Fabio Estevam

I have a i.MX53 quick start board, which is named in U-Boot and Linux mx53[_]loco. And yes, USB is working.

I need to check, what PMIC my board uses.

No, I tested on a board with the Dialog PMIC, and it worked flawlessy. Maybe someone else tesetd with a newer board..

I have both boards here.

On a mx53loco with Dialog PMIC:

MX53LOCO U-Boot > usb start (Re)start USB... USB: Register 10011 NbrPorts 1 USB EHCI 1.00 scanning bus for devices... 2 USB Device(s) found scanning bus for storage devices... 1 Storage Device(s) found scanning bus for ethernet devices... 0 Ethernet Device(s) found

On a mx53loco with FSL PMIC:

MX53LOCO U-Boot > usb start (Re)start USB... USB: Register 10011 NbrPorts 1 USB EHCI 1.00 scanning bus for devices... cannot reset port 1!? 1 USB Device(s) found scanning bus for storage devices... 0 Storage Device(s) found scanning bus for ethernet devices... 0 Ethernet Device(s) found

I still have not figured out why it cannot reset the USB port in this case.

I managed to get USB working in the mx53loco board with FSL PMIC.

I needed to turn on VUSB regulator output of mc34708.

Will submit the patches after my initial Dialog PMIC series get applied.

Ok, this explains why it did not work !

Clear.
