For details refer to https://cesanta.com/blog/esp8266-flash-erasing-issue.shtml\r\nIt happens with current themadinvetor/esptool as well as the embedded esptool here. Since dev branch exceeds this limit for the float version, we're already in trouble now (integer version is briefly below the threshold).\r\n\r\nThis issue can't be resolved without a fix or workaround in esptool and other flashers."},"comment":{"url":"https://api.github.com/repos/nodemcu/nodemcu-firmware/issues/comments/136083807","html_url":"https://github.com/nodemcu/nodemcu-firmware/issues/594#issuecomment-136083807","issue_url":"https://api.github.com/repos/nodemcu/nodemcu-firmware/issues/594","id":136083807,"user":{"login":"projectgus","id":205573,"avatar_url":"https://avatars.githubusercontent.com/u/205573?v=3","gravatar_id":"","url":"https://api.github.com/users/projectgus","html_url":"https://github.com/projectgus","followers_url":"https://api.github.com/users/projectgus/followers","following_url":"https://api.github.com/users/projectgus/following{/other_user}","gists_url":"https://api.github.com/users/projectgus/gists{/gist_id}","starred_url":"https://api.github.com/users/projectgus/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/projectgus/subscriptions","organizations_url":"https://api.github.com/users/projectgus/orgs","repos_url":"https://api.github.com/users/projectgus/repos","events_url":"https://api.github.com/users/projectgus/events{/privacy}","received_events_url":"https://api.github.com/users/projectgus/received_events","type":"User","site_admin":false},"created_at":"2015-08-30T04:15:35Z","updated_at":"2015-08-30T04:15:35Z","body":"Just a heads-up, esptool.py has an additional maintainer now (me!) and we've just (finally) merged the fix for this issue to https://github.com/themadinventor/esptool\r\n\r\nIt's hard for one person to keep up with a popular project, but hopefully by sharing the work around esptool.py can continue to keep current."}}
