Hi everyone.
I'm trying to build an application which involve usb webcam interfacing. Here're what I've done:
- Install petalinux and Avnet-Digilent-ZedBoard-2015.4 BSP from Xilinx
- Configure the kernel's device drivers to enable UVC by doing:
petalinux-config -c kernel
Device Drivers > Multimedia Support > Media USB Adapter > USB Video Class (UVC) (also UVC Input Event Support)
- Exclude USB 2.0 OTG FSM Implementation in Device Drivers > USB Support
- the other configurations are left by default
- Build the kernel by running
petalinux-build
- Pack the boot image by runnung
petalinux-package --boot --fsbl <path_to_fsbl_elf> --fpga <path_to_download.bit> --uboot
- Copy BOOT.bin in the root folder of Avner BSP and image.ub in ./images/linux to SD card
- set the jumper, boot up the board from SD card and connect webcam in the USB OTG port
"dmesg | tail" shows nothing related to webcam, so does "ls /dev" (no videox device listed),
What did I miss? Please response.... I can't find support anywhere.
