Cannot open remote file for write

[curioussavage]

Hi thanks a million for this tool. I use it exclusively for uploading files to my wemos d1 minis.

I just flashed new firmware on my device with esptool and then use nodemcu-tool mkfs

I suspect this might be a symptom of an issue with that, either way it might be nice to add more detail/ suggestions to the error message if relevant.

and of course if you have any idea how I can fix this much a appreciated

here is the output.

As you should be able to see in the screen shot it creates the files on the device but writes nothing to them.

I tested in the terminal and was able to open and write to the empty file created by nodemcu-tool upload so it looks like it might be an issue with the lib and maybe the newest firmware?

Strange... i didn't test v1.5.4 yet
did you tried an earlier firmware version ? e.g. 1.5.1 ?

generally, there are no more details available... the fs.write function will only return false..

[AndiDittrich]

i can confirm the issue with NodeMCU Firmware v1.5.4 - i will investigate the issue asap

[AndiDittrich]

should be fixed within the current master branch of NodeMCU-Tool
The team of NodeMCU LUA has changed the footprint of file.open within the last minor release...

Thank you very much for your report @curioussavage
