Hi @mj07

Would you post the kernel log?

Hi @mj07 ,
I notice that you are using a new firmware, judging from the line:

[ 0.000000] Linux version 4.4.154 (daijh@tchip14) (gcc version 6.3.1 20170404 (Linaro GCC 6.3-2017.05) ) #136 SMP Sun Jan 27 09:49:23 CST 2019

Copy the code

Are you using the firmware in the "AI 64G USB Disk"?

What firmware (contains u-boot, kernel, and root filesystem etc) did you use?I mean the Rockchip firmware, not the GTISDK.

The Rockchip firmware in the usb disk is specialized for the GTI chip, containing
all the kernel patches necessary, which may not be within other general firmware
you find in the download page of our website.

prefix your command with "sudo" and try, like:

sudo ./liteSample

The device node of /dev/mmcblk1 requires root permission to do the ioctl.
