The only difference is adding:

CONFIG_USB_ACM=y

Best regards,

I've changed script to avoid checking if device is removable.
Another problem was with naming convention: in my system  first partition on SD card is /dev/mmcblk0p1, but scripts expects something like /dev/sdd1. When invoked "cb_part_install_flash_card mmcblk0 pack" it tries to create partition name by adding a partition number, so instead of mmcblk0p1 it makes mmcblk01.
After changing this behavior scripts ended successfully.

I found following problem with building ubuntu image:

cat /sys/block/mmcblk0/removable

0

This prevents creating image of system, because it is checked by cb_part_install_flash_card

OK. I was able to compile kernel for debian server on my laptop with Ubuntu 14.04, but havent managed to generate image (scripts says, that my SD card is not removable). I was able to replace manualy kernel in Debian Server image so  was able to use this driver, but doing the same on Ubuntu image made system unbootable.

I've just installed linaro-server-trusty-cb4-emmc-hdmi-v1.0.img.7z image on my CB4.
There is no cdc-acm module available by default. How to add this module?

Best regards,

ZG
