Some basic questions

Postby zliudr » Fri Oct 11, 2019 5:35 pm

I'm just learning the toolchain. In all examples I encountered online the sample projects are built with make command. There also seems to be files for Cmake. So these Cmake related files can be left alone when all I'm using is make, correct?

Continuing on make, if I run "make flash" or "make app-flash", what is the difference? The documentation didn't explain what ELSE is there besides app and what app includes. For example, the various libraries and subsystems that are compiled for the first time, are they all belonging to the ELSE? Is the app only within say the example code folder?

To change partitions, I have to erase flash first and then set partition table in menuconfig, then make flash, correct?

Make alone doesn't erase existing partitions such as spiffs, right?

Yes, ignored.

Run 'make help'

Very short response, like last time. Well, the help wasn't very helpful. If make flash uploads the partition table, does it also erase the partitions? My suspicion is it doesn't erase the spiffs. This forum seems to have some visitors but not many are helping. You got great hardware and the firmware is extensive. But without the people to support, it's not going to achieve its full potential.

Selective erase based on what needs to be written.

flash = partition table, bootloader and the app
app-flash = flashes only the application, nothing else.

Thanks! That was clear.
