Saves about 1000 bytes of heap RAM for a bare boot with filesystem. esp8266/scripts/_boot: builtins is no longer used. 2016-04-29T17:04:17+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-04-29T17:04:17+00:00 urn:sha1:74f413bc600f422695392fda3cf09008a6f33ded esp8266/scripts: Move all of initial setup to inisetup module. 2016-04-29T17:02:59+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-04-29T17:02:59+00:00 urn:sha1:d86d65f6251b07e0d4a1751e2ba7f27a73604b89 esp8266/scripts/_boot: Print notice when initial setup is executed. 2016-04-20T15:01:09+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-04-20T10:47:56+00:00 urn:sha1:584406880c8354d87a714f934e1984393ec76c3b esp8266/scripts: Don't try to create filesystem on 512KB devices or less. 2016-04-18T14:14:00+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-04-18T14:14:00+00:00 urn:sha1:8dcce9260614aca9f89a346a31ca47e2b1288398 There's no space for it. esp8266/scripts/_boot: Mount block device on "" instead of "/". 2016-04-14T21:56:21+00:00 Damien George damien.p.george@gmail.com 2016-04-14T21:56:21+00:00 urn:sha1:7d2c685544bba08ea5f027d674f35bc0f4bc9a54 "" is the correct name of the root directory when mounting a device there (as opposed to "/").

Otherwise, it checks if flash is empty, and if so, performs initial module setup: makes FAT FS, configures default AP name, etc. As a last option, if flash is not empty, and could not be mounted, it means filesystem corruption, and warning message with instructions is printed in an infinite loop.
