From bb00a015d624f683c66c9e30341f93b678d03d2e Mon Sep 17 00:00:00 2001 From: =?utf8?q?Petr=20=C5=A0tetiar?= Date: Fri, 23 Nov 2018 14:37:52 +0100 Subject: [PATCH] usb: gadget: f_sdp: Provide filesize env variable for downloaded images MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Currently it's not possible to get filesize of downloaded images and it's impossible to automate some tasks in scripts. So this patch adds `filesize` environment variable with size (as hex number in bytes) of the last successfully downloaded file via `sdp` command.
