Hi johnex,
Thanks for the answer.

I followed the steps at above mentioned link and encountered following issue.

faheem@faheem:~/gl_imagebuilder$ ./gl_image -p ar300m -e “openssh-sftp-server nano htop”
Already up to date.
Profile “GL-AR300M” does not exist!
Use “make info” to get a list of available profile names.
Makefile:185: recipe for target ‘_check_profile’ failed
make[1]: *** [_check_profile] Error 1
Makefile:192: recipe for target ‘image’ failed
make: *** [image] Error 2
Failed to build GL-AR300M…

where “GL-AR300M” profile supposed to be present? How to overcome this issue?

NOTE: I want to build firmware for NAND flash.

Regards,
Faheem
