Try passing the -fm dio option to write_flash. Writing to flash with qio mode will succeed but the chip can’t read the flash back to run - so nothing happens on boot. Some devices only support the dio flash mode. If esptool can flash your module with write_flash but your program doesn’t run, check the following: Wrong Flash Mode 

Power stability problems may also cause this (see Insufficient Power.) Writing to Flash Succeeds but Program Doesn’t Run  If flashing fails with random errors part way through, retry with a lower baud rate. Writing to Flash Fails Part Way Through  Try using a slower baud rate ( -b 9600 is a very slow value that you can use to verify it’s not a baud rate problem). If you have connected other devices to GPIO pins, try removing them and see if esptool starts working. Check the voltages at each pin with a multimeter, “high” pins should be close to 3.3V and “low” pins should be close to 0V. A common pitfall is leaving a serial terminal accessing this port open in another window and forgetting about it.Ĭheck the chip is receiving 3.3V from a stable power source (see Insufficient Power for more details.)Ĭheck that all pins are connected as described in Boot Mode Selection.

If you see errors like “Failed to connect” then your chip is probably not entering the bootloader properly:Ĭheck you are passing the correct serial port on the command line.Ĭheck you have permissions to access the serial port, and other software (such as modem-manager on Linux) is not trying to interact with it. Try the suggestions here if you’re having problems: Bootloader Won’t Respond  Essentially, Wine is trying to re-implement enough of Windows from scratch so that it can run all those Windows applications without actually needing Windows.Flashing problems can be fiddly to troubleshoot. Wine is an open-source Windows compatibility layer that can run Windows programs directly on any Linux desktop. Wine is a way to run Windows software on Linux, but with no Windows required.

You can also try PlayOnLinux, a fancy interface over Wine that will help you install popular Windows programs and games. Once installed, you can then double-click the app to run them with Wine. Download Wine from your Linux distributions software repositories. From the OnWorks Windows OS you have just started, goto our file manager with the username that you want. Start any OS OnWorks online emulator from this website, but better Windows online emulator. Upload this application in such filemanager. Enter in our file manager with the username that you want.
