Including files in MicroPython.bin #306

Open behackful opened 5 years ago

behackful commented 5 years ago

Hi, I'm trying to solve this thing for 2 days now. I want to create a firmware.bin that will include some files(main.py, some HTML and css etc) that will be in the flash memory but I just can't find a way to do it.

The only way I found, that is not really logical, is to add another function in the vfs_native.c file, same as the function that checks if "boot.py" exists and creates it for main.py file (or any other file).

I know that I can create an image with the files but the problem is that I need one file because I intend to work exclusively with OTA updates.

Is there something I'm missing? I tried to freeze the required files but it only works for python scripts.

I haven't experimented with OTA yet but very interested. With ordinary building and flashing you can create two images; a 'firmware' and a filesystem image that you install onto the device separately. Could you do the same kind of thing with OTA? Looks like the firmware image gets pulled down from a server with FTP and then installed locally. Could the same kind of thing happen with a filesystem image?

Sorry, no.

Enable FTP or telnet (in menu config) and you can add any file you like in run time.

Hey guys! did you have any progress on this? I am also having same doubt. I want to implement OTA. I checked from docs that '.bin' can be written on another partition (other than from current). However, this .bin file is the firmware, its not main.py or boot.py (which I want to update). Please correct, if I am wrong here. I looked for other methods like using github project etc, but it doesn't look like secure method. Can we put main/boot.py directly in the ota_partition using ota module included in lobo micropython? will that work? Can we include main.py/boot.py in the 'micropython.bin'. [I know that separate file image can be created and flashed as @behackful mentioned ]. @nissimzur could you please elaborate which you mentioned? Thank you.
