Troubleshooting
Troubleshooting
- FAQ
- I am getting “espcomm_sync failed”, “esptool.FatalError”, etc. How to resolve this issue?
- Why esptool is not listed in “Programmer” menu? How do I upload ESP without it?
- My ESP crashes running some code. How to troubleshoot it?
- How can I get some extra KBs in flash ?
- About WPS
- This Arduino library doesn’t work on ESP. How do I make it work?
- In the IDE, for ESP-12E that has 4M flash, I can choose 4M (1M FS) or 4M (3M FS). No matter what I select, the IDE tells me the maximum code space is about 1M. Where does my flash go?
- I have observed a case when ESP.restart() doesn’t work. What is the reason for that?
- How to resolve “Board generic (platform esp8266, package esp8266) is unknown” error?
- How to clear TCP PCBs in time-wait state ?
- Why is there a board generator and what about it ?
- My WiFi won’t reconnect after deep sleep using WAKE_RF_DISABLED
- My WiFi was previously automatically connected right after booting, but isn’t anymore
- How to resolve “undefined reference to flashinit” error ?
- How to specify global build defines and options?
- Exception causes
