On website you list other boards than Pi as usable with Emteria. Is it possible on platforms that have eMMC to install Emteria on the eMMC instead of keeping it on an SD card ? Looking for the more reliable solution
Is there a documentation on how to do that and boards supported for that feature ??
It depends on the board. For example, RPi compute module uses an additional tool: https://www.raspberrypi.org/documentation/hardware/computemodule/cm-emmc-flashing.md
