Re: USB Host on OMAP3 EVM, 2.6.29
Hi Eikka. Am not familiar with OMAP35xx. Also don't know, what's the config of EVM (if it uses twl4030 tranceiver or external). Can it play as a HOST which is the case to supply VBUS ? Otherwise external self-powered hub might be needed. -niilo- On Wed, 2009-05-27 at 02:59 +0200, ext Eino-Ville Talvala wrote: > Hi, > > We're trying to get basic USB host mode up and running on a OMAP3530 > EVM, with no success.

USB Host on OMAP3 EVM, 2.6.29
Hi, We're trying to get basic USB host mode up and running on a OMAP3530 EVM, with no success. We're (now, after many permutations of kernels and .config settings) using the vanilla 2.6.29-omap1 kernel plus the AUTOIDLE fix from Niilo Minkkinen), with slight additions to board-omap3evm to allow the MMC slot to work since it hosts the rootfs (missing regulator setup, as per dfoley's mail on 3/25). All we've done with configuration past omap3_evm_defconfig, is to compile in the MMC driver (to allow boot from it), enabling the EHCI host driver (doesn't work with it off, either), and setting the integrated USB driver to Host mode. Listed below is the resulting .config file. We've tried many other configurations, but nothing has worked any better. I'd very much appreciate it if anyone knows what magic sauce might be missing here - the USB bus debug messages indicate that the bus is being discovered, and powered up, but no voltage appears on the USB VBus line, and no devices are detected when they're plugged in. Sometimes we've seen auto-suspend messages indicating that the bus is auto-suspending, and other times we've seen nothing - but no matter what, it doesn't seem to work. Below is the output of "dmesg | grep 'usb\|hub' " for the above configuration with a USB keyboard plugged in, followed by the .config file: Thanks, Eino-Ville Talvala Graduate Research Assistant Computer Graphics Laboratory Stanford University -- twl4030_usb twl4030_usb: HW_CONDITIONS 0x50/80; link 1 twl4030_usb twl4030_usb: Initialized TWL4030 USB module usbcore: registered new interface driver usbfs usbcore: registered new interface driver hub usbcore: registered new device driver usb musb_hdrc: version 6.0, musb-dma, host, debug=0 musb_hdrc: ConfigData=0xde (UTMI-8, dyn FIFOs, bulk combine (X), bulk split (X), HB-ISO Rx (X), HB-ISO Tx (X), SoftConn) musb_hdrc: MHDRC RTL version 1.400 musb_hdrc: setup fifo_mode 4 musb_hdrc: 29/31 max ep, 15424/16384 memory musb_hdrc: hw_ep 0shared, max 64 musb_hdrc: hw_ep 1tx, max 512 musb_hdrc: hw_ep 1rx, max 512 musb_hdrc: hw_ep 2tx, max 512 musb_hdrc: hw_ep 2rx, max 512 musb_hdrc: hw_ep 3tx, max 512 musb_hdrc: hw_ep 3rx, max 512 musb_hdrc: hw_ep 4tx, max 512 musb_hdrc: hw_ep 4rx, max 512 musb_hdrc: hw_ep 5tx, max 512 musb_hdrc: hw_ep 5rx, max 512 musb_hdrc: hw_ep 6tx, max 512 musb_hdrc: hw_ep 6rx, max 512 musb_hdrc: hw_ep 7tx, max 512 musb_hdrc: hw_ep 7rx, max 512 musb_hdrc: hw_ep 8tx, max 512 musb_hdrc: hw_ep 8rx, max 512 musb_hdrc: hw_ep 9tx, max 512 musb_hdrc: hw_ep 9rx, max 512 musb_hdrc: hw_ep 10tx, max 512 musb_hdrc: hw_ep 10rx, max 512 musb_hdrc: hw_ep 11tx, max 512 musb_hdrc: hw_ep 11rx, max 512 musb_hdrc: hw_ep 12tx, max 512 musb_hdrc: hw_ep 12rx, max 512 musb_hdrc: hw_ep 13tx, max 512 musb_hdrc: hw_ep 13rx, max 512 musb_hdrc: hw_ep 14shared, max 1024 musb_hdrc: hw_ep 15shared, max 1024 musb_hdrc: USB Host mode controller at d80ab000 using DMA, IRQ 92 musb_hdrc musb_hdrc: MUSB HDRC host driver drivers/usb/core/inode.c: creating file 'devices' drivers/usb/core/inode.c: creating file '001' musb_hdrc musb_hdrc: new USB bus registered, assigned bus number 1 usb usb1: default language 0x0409 usb usb1: New USB device found, idVendor=1d6b, idProduct=0002 usb usb1: New USB device strings: Mfr=3, Product=2, SerialNumber=1 usb usb1: Product: MUSB HDRC host driver usb usb1: Manufacturer: Linux 2.6.29-omap1-05531-g0dfe43a-dirty musb-hcd usb usb1: SerialNumber: musb_hdrc usb usb1: uevent usb usb1: usb_probe_device usb usb1: configuration #1 chosen from 1 choice usb usb1: adding 1-0:1.0 (config #1, interface 0) usb 1-0:1.0: uevent hub 1-0:1.0: usb_probe_interface hub 1-0:1.0: usb_probe_interface - got id hub 1-0:1.0: USB hub found hub 1-0:1.0: 1 port detected hub 1-0:1.0: standalone hub hub 1-0:1.0: individual port power switching hub 1-0:1.0: no over-current protection hub 1-0:1.0: power on to power good time: 10ms hub 1-0:1.0: 100mA bus power budget for each child hub 1-0:1.0: local power source is good hub 1-0:1.0: enabling power on all ports drivers/usb/core/inode.c: creating file '001' hub 1-0:1.0: state 7 ports 1 chg evt usbmon: debugfs is not available drivers/usb/core/inode.c: creating file '002' usb usb2: default language 0x0409 usb usb2: New USB device found, idVendor=1d6b, idProduct=0002 usb usb2: New USB device strings: Mfr=3, Product=2, SerialNumber=1 usb usb2: Product: OMAP-EHCI Host Controller usb usb2: Manufacturer: Linux 2.6.29-omap1-05531-g0dfe43a-dirty ehci_hcd usb usb2: SerialNumber: ehci-omap.0 usb usb2: uevent usb usb2: usb_probe_device usb usb2: configuration #1 chosen from 1 choice usb usb2: adding 2-0:1.0 (config #1, interface 0) usb 2-0:1.0: uevent hub 2-0:1.0: usb_probe_interface hub 2-0:1.0: usb_probe_interface - got id hub 2-0:1.0: USB hub found hub 2-0:1.0: 3 ports detected hub 2-
