HI all,
We are trying to bring up a board based on Freescale's MPC8548 SoC and we are facing issues with USB controller present on PCI. (PCI_1 <=> USB2.0 PCI host controller <=> USB flah driver controller <=> NAND flash). The issue that we are facing is with ehci_reset() returning failure condition (TIMEOUT).
Below is the corresponding section:
USB: EHCI fail to reset Error, couldn't init Lowlevel part
We have defined CONFIG_PCI_EHCI_DEVICE, CONFIG_USB_EHCI_PCI in our case and populated the static struct pci_device_id ehci_pci_ids[] structure with the supported ids in drivers/usb/host/ehci-pci.c.
"usb info" command under u-boot shows only the USB HUB, ideally it should have detected even the storage device. => usb info 1: Hub, USB Revision 2.0 - u-boot EHCI Host Controller - Class: Hub - PacketSize: 64 Configurations: 1 - Vendor: 0x0000 Product 0x0000 Version 1.0 Configuration: 1 - Interfaces: 1 Self Powered 0mA Interface: 0 - Alternate Setting 0, Endpoints: 1 - Class Hub - Endpoint 1 In Interrupt MaxPacket 2048 Interval 255ms
=>
Can anyone provide any pointers on how resolve the issue ?
