This would cause an exception when _boot.py was executed during startup. esp8266/modules: Mount filesystem at root when creating for first time. 2017-05-26T07:05:58+00:00 Damien George damien.p.george@gmail.com 2017-05-26T07:05:58+00:00 urn:sha1:eea584860dc65203dcae407819c2f139c1f71214 esp8266: Change default settings to mount flash at root dir. 2017-05-05T10:15:10+00:00 Damien George damien.p.george@gmail.com 2017-03-10T06:14:21+00:00 urn:sha1:e62235f8c755b270e478f403d8ac75c5192847ba esp8266: Change to use new generic VFS sub-system. 2017-01-27T06:21:45+00:00 Damien George damien.p.george@gmail.com 2017-01-27T04:16:08+00:00 urn:sha1:f9ecd484bbd698c0f85a3f40f391afeb01940052 The VFS sub-system supports mounting of an arbitrary number of devices (limited only by available RAM). The internal flash is now mounted at "/flash". esp8266/_boot.py: Decrease GC alloc threshold to quarter of heap size. 2016-07-23T10:56:24+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-07-23T10:56:24+00:00 urn:sha1:0d221775f5ab458358ee873b70ad16f284a9b1cb The idea behind decrease is: bytecode and other static data is also kept on heap, and can easily become half of heap, then setting threshold to half of heap will have null effect - GC will happen on complete heap exhaustion like before. But exactly in such config maintaining heap defragmented is very important, so lower threshold to accommodate that. esp8266/_boot.py: Set GC alloc threshold to half of heap size. 2016-07-22T21:20:49+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-07-22T21:20:49+00:00 urn:sha1:c141584e1e30b6dd2268d8831b706dcb9ab25c7c Should keep good chunk of heap unfragmented, if a user application allows that at all. esp8266: Explicitly collect garbage in bootstrap scripts. 2016-07-02T16:22:55+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-07-02T16:20:13+00:00 urn:sha1:686367dcfc6cb0a930fbfee03399b706eb76eae7 Leads to less fragmentation at teh time user code starts. esp8266: Enable frozen bytecode, with scripts in modules/ subdir. 2016-06-29T12:59:19+00:00 Damien George damien.p.george@gmail.com 2016-05-11T15:57:29+00:00 urn:sha1:db80c0ed4678f4bacc6c7c9b67cbf26846fc21be To start with, the critical scripts _boot.py and flashbdev.py are frozen to improve performance and reduce RAM consumption. Saves about 1000 bytes of heap RAM for a bare boot with filesystem.
