From: Viresh Kumar Date: Wed, 20 Jul 2016 23:39:00 +0000 (-0700) Subject: greybus: firmware: Improve test application X-Git-Tag: v4.14-rc1~2366^2~378^2~21^2~120 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=adac4b95941189ca301759a67da4a132fc2804d5;p=platform%2Fkernel%2Flinux-rpi.git greybus: firmware: Improve test application It can take arguments not and we can perform all the operations with a single binary, sorry for missing that initially. Usage: ./firmware And all of them have default values, etc. Tested with a semco 13 MP module.
