Leaving
blockEraseparameter atfalsewhen constructing aPartitionStreamwill result in corruption unless partition has already been erased. This is not always immediately apparent so can be difficult to diagnose.Breaking change Replacing
blockErasewith an enumeratedmodeparameter enforces read-only behaviour by default (new feature and a good thing), with write access more explicitly defined. It's a simple change to existing code and will ensure it gets manually checked to ensure correct behaviour.Update the
Basic_Otasample to check that an OTA update is not being attempted on the active running partition. This can happen with esp8266, for example, when running in temporary boot mode. (NB. Other checks may include active filing system partitions but that is application-specific.)Update notes on migrating from Sming 4.2 to include updating boot sector. (Learning points froim existing Sming 4.2 based app - OTA to 5.1 #2727.)
Remove redundant flashsize calculation from rboot and update version string to
Sming v1.5(from v1.4.2). Note this should have been done in Add rBoot partition support #2258.Fix rboot README regarding use of slot 2, should correspond with subtype
ota_2notota_1.
