Hi Nayana,

It looks like file system is not readable in the memory.

How are you building the image?

How are you flashing the image into SD/MMC?

Hello Carlos_Musich

Thank you for the reply. I am building image using bitbake core-image-minimal command in build directory and i am flashing image into MMC .

Hi Nayana,

in your log I noticed that MMC 0 is default.

U-Boot 2016.07+fslc+ge6b4241 (Dec 20 2016 - 18:44:32 +0530)

CPU: Freescale i.MX7S rev1.2 at 792MHz

CPU: Extended Commercial temperature grade (-20C to 105C) at 57C
Reset cause: POR

Board: WARP7

DRAM: 512 MiB

MMC: FSL_SDHC: 0

but you are trying to boot from MMC2

Kernel command e=ttymxc0,115200 root=/dev/mmcblk2p2 rootwait rw

So you need to stop in U-boot and edit mmcroot variable to match MMC0.

Best regards,
Carlos

Hello Carlos

I am working on warp7 camera module, as i seen in the menuconfig file the OV5640 camera module is enabled but when i load the image i am not getting OV5640 module in that image. can you tell me is there any other way to enable the camera in warp7 and to check same using commands after flashing image.

Thanks and regards
