I have been failing to enable USB support for storage media such as USB flash disk on ccardwmx28js using DiGi EL.
Version information is as follows.
/ # uname -a
Linux ccardwmx28js 2.6.35.14 #5 Mon May 5 14:13:38 SGT 2014 armv5tejl GNU/Linux
I have enabled following options as mentioned in “Digi ESP™ for Embedded Linux - Documentation” while building kernel.
USB_SUPPORT
USB_EHCI_HCD
USB_EHCI_ARC
USB_EHCI_ARC_H1
USB_EHCI_ARC_OTG
USB_DEBUG
USB_ANNOUNCE_NEW_DEVICES
I also have done the jumper settings (J5 and J6) as mentioned in “ConnectCard™ for i.MX28™ Hardware Reference” manual.
I also have enabled BLK_DEV_SD in SCSI device support.
When I connect the USB flash disk nothing gets detect on the board. No kernel messages in dmesg. No messages in /var/log/messages. Nothing gets mounted on tmp/media/ . No new devices gets detected in /dev directory.
Have I missed any other configuration?
Could anyone please help me with this? Really have been having very tough time to enable anything on DiGi boards.
