Banging my head against the wall
Posted: Fri Sep 25, 2020 6:39 am
I am trying to set up a factory NVS partition that will hold data that will not be erased across reset to factory. This is covered in https://docs.espressif.com/projects/esp ... uring.html and several other sites. The process is to convert a .csv file with the persistent data to a .bin file, then to write the .bin file to a factory NVS partition separate from the modifiable configuration NVS partition. I've written a prototype .cvs file named PBmfgCfg for testing the process that looks like this:
The conversion of this .csv file to a .bin file is supposed to be done by invoking nvs_partion_gen.py, which I have done from where it lives in the esp-idf as well as from my project directory, (where I copied the utility to avoid typing any path), and I get the same error result regardless.
I invoke the following command line in cmd.exe as follows:
which according to "nvs_partion_gen.py -h", is the correct way call the program with args, (the 0x6000 is the size of the factory NVS partition table segment) and get the following error result:
What is the problem here? What am I doing wrong?
