esptool merge_bin: error when file system exists in build folder.

[i-windows]

firstly - I love it.

if I have a file system already in my build folder, when I build I get this error, which I'm not sure if it is to be expected. if I delete the file system, then all compiles file.

Converted to a discussion since this is not a bug related to the project but a usability issue.

Hello,
Thanks!
You are doing quite custom thing and I cannot help because I do not know what you are building your firmware size and partition table (although I could guess with the CLI but not entirely). If you look at the doc, I advise to use the factory.py script, that you can also update according to your needs.
You have a project on github to show me ?

not really anything special. Just took a small project that creates displays data from index.html, stored in \data. using your partition layout etc. the data is in littleFS, which shouldnt be an issue but doesnt get uploaded.

and now a minute or two after typing this, it works! I hate computers
Started.
Listing all partitions...

yes that works. I am more used to this file and this representation:
partitions.csv

thanks, I'm a bit of a beginner and didn't know that tool existed. very nice.

I have a couple of devices which have no serial only wifi, they had an OTA option so I managed to flash them with my own firmware, which runs elegantOTA. I was going to try and use this OTA option to flash your safeboot, but this doesnt work, which is kind of expected. I would ned to find a way to flash with esptool at 0x0 OTA, which I dont think is possible, but I need to do some research. this is not an issue, just an interesting use case - maybe a rather odd one. but fun.
