In preparation for moving my application from my development board to the world at large, I need to make sure that my application includes an FTP server with the required characteristics so that I can upload image.bin files to it when a firmware upgrade is required.
I'm unclear as to the precise settings I need to incorporate to make this work; there are a couple of different FTP server examples in ESP, but I can't find a clear statement of what is needed to enable deployment.
For example, if I create a project using the standard Wizard, which calls the initAppServices() routine from its root.c file, it seems I obviously need to have the macro FTP_SERVER_ENABLED defined as TRUE (in appservices.h), but do I also need to have FLASH_FILESYSTEM_ENABLED defined as well? The latter does not seem to be defined by default.
I don't need to have a directory structure as such within my device's flash memory, but I would like to be able to store one other file, an XML configuration file. Can this go into the same directory (or into the root directory) along with the image.bin file? Or do I need to create a dedicated driectory for it?
