The latter is renamed to DS18X20 to reflect the fact that it will support both the "S" and "B" variants of the device. These files are moved to the modules/ subdirectory to take advantage of frozen bytecode. esp8266/modules/flashbdev: Start filesystem at 0x90000. 2016-08-09T11:59:27+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-08-09T11:59:27+00:00 urn:sha1:3c9510d7670b79d7a964ab5b76f734bc87c63087 To accommodate growing firmware. esp8266/flashbdev: Reserve extra sysparam sector for SDK 2.0.0 compatibility. 2016-08-06T12:21:49+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-08-06T12:21:49+00:00 urn:sha1:ca59f5f208f17620a0ac2fc77e3026bed0d9fe2c 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: Switch webrepl to use frozen bytecode. 2016-07-02T19:45:31+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-07-02T19:45:31+00:00 urn:sha1:b8f45166c631d67f9426fc1a561ab9f27c16cb1d esp8266: Switch webrepl_setup to use frozen bytecode. 2016-07-02T19:40:16+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-07-02T19:40:16+00:00 urn:sha1:dec51e3519ac6f8ab2ffd0cf00407a505742248f 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.
