I'm somewhat really dissapointed. You are selling a device with sdcard slot, but in general the sdcard slot ist unusable.
I have code which is running in host and standalone mode on the main branch (not needing sdcard). But when I want to run the same code with the branch sdcard_support, the code only works in host mode. The only thing the code is doing: Serving the file system. So about nothing what could break. A nice side effect: The device is soft bricked after flashing the application.
I have one idea for a reason. Running the code in standalone in the main branch, the webserver serves the directory /media/mmcsd-0-0/ with the application file in it. In host mode this is not existing. But this is also the folder where the sdcard is mounted. So i think there is a conflict with that path and possibly the application cannot be loaded, since its not on the sdcard, which is now mounted at that path.
