Difference between esptool-ck and esptool.py? #34

Closed rayshobby closed 8 years ago

rayshobby commented 8 years ago

This is really a question instead of an issue. I am curious how esptool-ck is different from esptool.py (other than the obvious differences in the command line parameter names)? The reason I am asking is that when I flashed a firmware (compiled in Arduino) that uses SPIFFS, with esptool.py the device always fails to mount SPIFFS, while with esptool-ck it works fine. I am curious to find out why. Thanks.

The issue you are seeing might be related to the way esptool.py modifies binary image header. Esptool-ck sets the flash chip size field of the binary image header when the .bin file is generated. Esptool.py, on the other hand, modifies this field when .bin file is loaded into flash. I think you can work around this by passing correct flash size parameter to esptool.py when you upload.

OK, that makes a lot of sense. I will try it later. Thanks for the explanation.
