Unable to flash app

[OPatrick]

Hello, Mongoose first install went ok. Can see files in devices. But flashing an example (Arduino basic usage) is not possible and led to this error:

Calling: Sys.GetInfo [Sep 4 19:16:10.270] E0904 19:16:10.270144 5556 ui.go:513] Call complete, error: context deadline exceeded [Sep 4 19:16:10.270] E0904 19:16:10.270144 5556 reconnect_wrapper.go:72] [reconnectWrapperCodec to COM5; connecting...] Connection closed

Same for any ap example. I did request "Rebuild App" before "Flash App firmware to device". Flasher can not be stopped. Have to kill mos.exe (windows 10). Thanks

I'm having the same issue, here's the output from the mos tool under windows 10 with verbose 4: https://gist.github.com/benjamind/5d7d574be8df9be870fcfdf12a532dec

Could you confirm that there is no other mos.exe processes hanging around ?

[OPatrick]

Thanks for your interest :-) No other mos.exe listed by windows task manager. Upgrading the tool recently did not make things better (mos-esp32-1.15 nor iot-kit-esp32-1.15) Attached error log error.txt

But... I've seen this related subject: https://forum.mongoose-os.com/discussion/1579/unable-to-finish-flashing-device-setup-with-webui-esp32 I did it "mos flash mos-esp32-1.14" and it kind of worked! (the flashing LED in the init.js example was not flashing, but I could see the device Logs in the IDE Tried to re-flash with ide via "Device Setup" window but failed again with the above error message. Trying "mos flash mos-esp32-1.15" is just making the command line no more responding.

what board you're flashing to? from the logs i see that the USB connection is quite flaky, and several attempts are required for success.

Hello, Well, I'm using this board: TOGO which is a clone of this one: HelTec But also on this board with same results: Weemos What is strange is that I never encountered any connection problem under Arduino IDE nor Platform IO... Flashing is always a breeze... Because I cannot use Mongoose-OS yet, I continue my work on Platform IO. And is goes well so far. But I am desperate to use MOS ;-) I also tried different ports on the PC (laptop ASUS ROG with windows 10 + 16 go RAM) Thanks for your help.

I am having the same problem with an ESP32 kit. I think it might be that RPC is not configured in the chip.

[jafetmorales]

It was not the RPC, in my case. I just needed to press the Boot and the EN buttons in my board and leave them pressed both until the flashing program that I am using attempted to connect to the ESP32 ROM for the 4th time. The flashing program said that everything was downloaded successfully, and the device happily replied "hello".

I have just updated mos tool to 1.26 but now I am unable to build programs
