The Revolution Pi Flat module has no USB eMMC Interface. Is it still possible to upload an image?
For the Revolution Pi Flat, there is ultimately only the possibility to set up over-the-air updates and thus exchange images. The prerequisite is that an executable image is on it beforehand. http://mender.io is such a tool or Ansible could also be used for this. Since our image is based on Debian or Raspberry Pi OS, you have all the other possibilities of the Linux world at your disposal.
Alternatively, you can use this guide:

The _config.rsc file is empty in Revolution Pi Flat. What can I do?

If there hasn't been any configuration by the end-user in PiCtory: Yes, this is normal. The configuration is usually done via PiCtory. You can find a tutorial in our documentation:
