NCC chip not recognised

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"?

I've used "AI 64G USB Disk"'s version GTISDK version- V3.4, but getting same issue with that so I've downloaded GTISDK version- V4 from GTI portal.

Problem with both versions are same like..MMC_WRITE_MULTIPLE_BLOCK ioctl failed err = -1

How to deal with this problem?

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.

We have used same firmware as given in pen-drive, we have only used different GTISDK -Linux_aarch64_v4.0.0 instead of GTISDK_Linux_aarch64_v3-1-2a.

Please help.

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

sudo ./liteSample

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