Saves about 1000 bytes of heap RAM for a bare boot with filesystem. esp8266/scripts/flashbdev: Use all available Flash for filesystem. 2016-04-25T22:36:32+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-04-25T22:36:32+00:00 urn:sha1:237c519ac43060d766a611f30d9aa39dc277cd16 All Flash sans firmware at the beginning and 16K SDK param block at the end is used for filesystem (and that's calculated depending on the Flash size). esp8266/scripts/flashbdev: Correct bootloader flash size to match real size. 2016-04-20T15:07:34+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-04-20T10:48:33+00:00 urn:sha1:cc1ef76f887f8f56363e3e431ba17320cf99a533 Flash size as seen by vendor SDK doesn't depend on real size, but rather on a particular value in firmware header, as put there by flash tool. That means it's user responsibility to know what flash size a particular device has, and specify correct parameters during flashing. That's not end user friendly however, so we try to make it "flash and play" by detecting real size vs from-header size mismatch, and correct the header accordingly. esp8266/scripts/flashbdev: Disable debug output/checks. 2016-04-19T21:35:46+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-04-19T21:35:46+00:00 urn:sha1:2494399a42bff3b8286a4ccc7ae29e03645f230d 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/flashbdev: Use all available space in 1MB FlashROM for FS. 2016-04-17T22:23:04+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-04-17T22:23:04+00:00 urn:sha1:3a5a35aaeccfc03a45771b0a6f613d8ff25cd25f esp8266: Add Python modules for initial configuration. 2016-04-11T21:37:04+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-04-11T21:37:04+00:00 urn:sha1:40f5ecd3a82e810203b39131cb61474f101de58e Main entry point is _boot.py which checks whether FAT FS in flash mountable, and if so, mounts it. 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.
